The Bureau of Indian Standards (BIS)gave approval for printing of a new IndianStandard titled “Low-nickel austeniticstainless sheet & strip for utensilsand kitchen appliances” onDecember 27, 2010. This approval wasgiven at a meeting of the ‘Alloy Steel& Forging Sectional Committee,MTD 16 in Joint session with Lownickel Stainless steel for UtensilsMTD 16:1’ of the BIS. The meeting waschaired by Dr. Anil K Gupta, Director,Advanced Materials & ProcessResearch Institute, Bhopal. This newstandard will be given a number onlyafter the translation into Hindi and atthe time of printing sometime in 2011.
In order to achieve this, extensivechemical and mechanical tests wereconducted at TCR Engineering,Mumbai, on the various grades ofstainless steels under consideration.
Samples for these tests were suppliedby JSL and SSP.
The all important tests in food media(leaching of metallic ions and corrosion)were conducted at Central FoodTechnologies Research Institute (CFTRI),Mysore. For this, hundreds of sampleswere supplied by Salem Steel Plant and
Jindal Steel Ltd and the samples wereprepared under the supervision ofMr K R Ananathanarayanan, ISSDA’sconsultant based in Bangalore.
ISSDA wishes to place on record itssincere thanks to M/s TCR Engineering& CFTRI, Mysore, for conducting thesetests and to Mr. Ananthanarayan forvolunteering his services formeticulously analyzing each of thehundreds of tests and collating theresults.

Delhi Metro is a rapid transit system servingDelhi, Gurgaon, Faridabad and Noida inthe National Capital Region of India. TheDelhi Metro Rail Corporation (DMRC) hasalready commissioned a 65 Kms route inPhase-I and is going ahead with another128 Kms in Phase – II. Delhi Metro isplanning to cover the whole of Delhi andNCR region by 2020. By then, Delhi metrowill have covered a total of about 405.5 Kmsin Delhi and the National Capital Region(NCR).
Delhi Metro, which has become worldfamous for its state-of-the art transit systemand efficiency, started on a very positivenote by correctly specifying its metrocoaches in stainless steel type 301L. 301Lstainless steel was selected because ofits high strength which results inlightweight coaches, aesthetics, durability(more than 30 year life), minimummaintenance, and most important of all,passenger safety in case of crash or fire.
The first section of the Delhi Metro openedon December 24, 2002 and became verypopular and now has a ridership of 1.5million commuters per day. Delhi Metro hasbecome a boon for commuters who canescape steadily slowing traffic andcongested buses and can quickly get totheir destination in comfort and safety.
To cope with the huge rush the Delhi Metroare planning to start with six coach trainsinstead of 4 coach trains at present withone coach reserved for women. Usually,metro stations are spaced about 1 Kmapart within the city. DMRC operates trainsat a frequency of 2.5 minutes during peakhours.
Delhi Metro’s Expansion – A Big Market for Stainless Steel
CHENNAI TO HAVE ITS OWN METRO RAIL WITH STAINLESS STEEL COACHESChennai’s metro rail project was initiatedin 2007. Phase 1 consists of twointerconnected lines, linking NorthChennai to the Airport in the South andChennai Central to St. Thomas Mount. Itwill include 32 stations -19 equipped withfull size platform screen doors - over 45km (24 km underground and 21 kmelevated). These lines have been plannedwith a capacity to carry more than 500,000people daily and a frequency between twotrains as short as 3 minutes.
The Chennai Metro Rail Ltd (CMRL) hasplaced orders for the supply of 42 sets of4-car configuration (168 coaches),including supply of spares andmaintenance kits with the M/s AlstomTransport SA (ATSA) and Alstom ProjectsIndia (APIL) Consortium.
Stainless Steel Coaches of State-of-the-art design.
The cars will be of state-of-the-art designwith light weight shell made of Austeniticstainless steel with 3 phase AC drive andregenerative braking system. The car bodystructure will be manufactured in AusteniticStainless Steel AISI Types such as 201L,301L, 304 etc., with the exception of endunder-frames, which will be built in lowalloy high tensile carbon steel. In order toobtain lighter structures, the material ofeach structure will have the mostappropriate cold drawn grade of austeniticstainless steel for the load it carries.
The cars will have automatic trainprotection (ATP) and automatic trainoperation (ATO) systems. All cars are
provided with electrically operated bi-parting automatic sliding doors to ensuresafety of passengers. Besides, thesecoaches will be air conditioned and haveelectronic route map, public addresssystem, passenger emergency intercoms,video surveillance and CCTV. The initial lotof 36 coaches will be manufactured atLapa, Brazil. The remaining coaches areplanned for manufacture in India.
The first delivery of cars is planned for theend of 2012. Chennai Metro plans tocommence services partly by the end of2013. The entire project is scheduled tobe completed by 2015.
(Authored by Mr. R. Sriraman, formerly ofthe Indian Railways, now based inChennai)
By 2020, when the Delhi-NCR metro wouldcover about 405.5 Kms, Delhi Metro RailCorporation would need a fleet of more than2000-3000 coaches. Each coach would beusing over 10 tonnes of 301L for the skin,structural members, under-frame andfurnishing inside the coach. Type 301Lstainless steel is by far the standard gradeused the world over for metro coaches.
For covering 405.5 route-kilometers, DMRC would alsohave hundreds of MetroStations, which againgenerously use products usingstainless steel like escalators,handrails, benches, advertisingpanels, turn-styles, ticketingcounters etc. (See box item –‘Sustainable Stainless SteelTransit Station Design’ byCatherine Houska, NickelInstitute).
Other Indian cities like Mumbai, Kolkata,Chennai, Bangalore and Hyderabad arealso providing metro stations for itspopulation. Hence, the opportunities forproviding stainless steel products or sub -assemblies for metro coaches and metrostations are immense.

The aspirations and dreams of adedicated team, cherished and pursuedwith perseverance through three decadescame to fruition when the first cast of liquidstainless steel was taken through the newsteel melting facilities at Salem Steel Plantin September 2010. With major facilities inthe steel melting shop complex havingbeen put in position and after progressivesteps of trials and testing, stainless steelslabs have now started rolling out – therebydocking Salem Steel Plant in the next higherorbit - amongst world class integratedstainless steel producers of the world.
The Rs. 1900 crore expansion programmeat Salem inter-alia envisages setting up ofSteel Melting Shop with the following majorfacilities:
Along side, the CRM is also beingstrengthened with additional facilities likea third Annealing and Pickling Line, thirdSendzimir Mill, second Slitting Line,Tension Leveling line, Second Skin PassMill, roll grinders and other auxiliaryfacilities.
With this major step in its backwardintegration journey, Salem Steel Plant willnow be fully equipped to launch itself inthe mission of developing high-end gradesof stainless steel in-house for automobile,railway and other critical industrialapplications. With this major expansion,the capacity of saleable stainless steelproduction will go up from the present levelof 175,000 MT to 340,000 MT. This willcomprise of 146,000 MT of cold rolledstainless steel products and 194,000 MTof HR products.
Conceived in the early seventies as aspecial steels complex to produce 220,000MT of stainless, electrical and specialsteels, the Salem Steel Plant has had along and continuous tryst with its destiny.In March 1977, the formal go ahead wasgiven by Late Smt Indira Gandhi forimplementing this project through aprocess of “Reverse Integration” by settingup a 32000 tpa capacity Cold Rolling MillComplex with all associated facilities. Thefirst stainless steel coil rolled out exactlyafter 54 months in September 1981, settingnew standards in timely projectimplementation. Salem has never lookedback since then.
SALEM STEEL joins the elite group of integrated stainless steel millsStage after stage, brick by brick, this teamhas demonstrated resilience andcommitment - completing every stage ofexpansion dot on time with no cost / timeover runs and by 1991, a second SendzimirMill was added to increase the CRMcapacity to 70,000 MT. Reacting quickly tothe emerging market potential forstainless steel coin blanks in the country,
Salem added a 3000 tpa capacity CoinBlanking Line in 1993.
The next step in the backward integrationwas the addition of Hot Rolling Millcomplex with the state-of-the-art SteckelMill in 1995. And, latest and the final step inthis odyssey has been the completion ofthe steel melting facilities.
With a penchant for quality assurance andnew application developments, SalemSteel Plant had pioneered usage ofstainless steel in India - for coinage, railwaycoach components, architecturalapplications, appliances, roofing, bulksolid handling and wagon buildingapplications, to name a few.
The seeds of product developmentinitiated by Salem Steel decades ago inthe form of developing 409M grade forcorrosion and wet abrasion proneapplications has today germinated andblossomed into huge market segment in
the form of usage of stainless steel inrailway wagon building and materialhandling applications – revolutionizing therolling stock of Indian Railways. Thisindeed has been a classic illustration ofLife Cycle Cost (LCC) based valueengineering adopted by Indian Railwaysthat has substantially improved rolling
stock availability with considerably lessmaintenance outlay.
Salem Steel Plant produces and suppliesstainless steel sheets, coils and strips in200, 300 and 400 series and products aremarketed through branch network spreadacross the country at Delhi, Kolkata,Mumbai, Chennai, Ahmedabad, Pune,Hyderabad, Bangalore and Coimbatore. Inaddition to core products, Salem has alsoforayed into value added stainless steelproducts ranging from kitchenware, roofingsheets, pipes, tubes to other fabricatedproducts. Salem has recently engaged aService Center at Mumbai to providecustomized products to discerningcustomers.

Of all the water on this planet, 97% is salineand two per cent is in the form of glaciers.Only one per cent of water on earth isdrinkable. Out of this 1%, only one third isaccessible to human populations.
Global Situation: According toenvironmental scientists, the globalpopulation of over six billion people whichis increasing at a rate of around 80 millionpeople per year can only be supplied withclean water if we find a sustainable methodof converting saline water into clean water.
India: Figures from the ministry of ruralwater supply show that the country hadenough drinking water for its people in1951 at 5,177 cubic meters per person peryear. But by 2000 India had become awater-deficient country. In 2003, the countryhad a 25% deficit, at a rate of 1,500 cubicmeters per person per year. The deficit isprojected to rise to 33 per cent by 2025,unless measures are taken to resolve it.
India has a long coast line and this hugeresource offers the only solution to oururban centers which are already denselypopulated beyond their limits. Additional200 million people from the countrysideare expected to join urban areas in the nexttwo decades. This is the immensity of oururban infrastructure, providing water for thepopulation is just one of them.
Positive Action by the Indian Governmentto address Water problem: Surgingdemand for assured water supplies isforcing municipal corporations andindustrial entities to look beyond theconventional methods in trying to increasesupply. Various options such as rainwaterharvesting, waste water recycling anddesalination are being explored. Chennai,the metropolitan capital of Tamil Nadu haspioneered the use of large scale seawaterdesalination for producing potable water.
The Minjur Desalination plant, built on a60-acre site in Kattupalli, about 35km northof the state capital city, Chennai, will be thelargest desalination plant in India. Thesecond largest plant is in Jamnagar,Gujarat, with a capacity of 96,000m³/day.
The Minjur Reverse Osmosis Seawaterdesalination plant has a capacity of 100MLD (million litres per day). It commencedtrial operations in June 2010. It is alsoIndia’s first large scale seawaterdesalination plant dedicated to supply ofdrinking water for public consumption.Water from Minjur is pumped through 23.5
Seawater Desalination – A big opportunity for stainless steel
kms of pipelines to reach Madhavarampumping station in the city of Chennai. Thecost of potable water production fromseawater at Minjur is less than 5 paise perlitre.
Tamil Nadu has become a haven fordesalination projects as it has a coastlineof over 900 km and has over 70+ ongoingand commissioned desalination projectsof varying scales, using differenttechnologies. There are already severaldesalination plants in Tamil Nadu treatingbrackish ground water.
At Mundra in Gujarat, an even larger 25.2MLD Seawater Reverse Osmosis plant isnear completion for an upcoming 4000 MWUltra Mega Power plant.
The Gujarat government has envisagedself-sufficient townships on the coastalareas, complete with desalination andsolar power plants, solid wastemanagement, waste water treatment andrain water harvesting systems. Gujaratalready has several 30-40 MLDdesalination plants in operation.
By the year 2026, Mumbai will be the largestconsumer of water among coastal cities.The city alone would account for 55% ofthe total water demand of Maharashtra.Given the unbridled construction activityand growing population the monsoonsmay not be enough to meet its water needs.Mumbai’s demand is 4,250 MLD but thesupply from its six water sources is only3,400 MLD.
In anticipation of such a scenario, theMumbai Metropolitan Region Development
Authority (MMRDA) has decided to set uptwo desalination plants of 100 MLD each.One of the desalination plants will be forSouth Mumbai and the other for thesuburbs and areas outside Mumbai suchas Mira-Bhayander. It comes nearly a yearafter the Brihanmumbai MunicipalCorporation (BMC) decided on a similarmove. In the long term, MMRDA is lookingat 1,500 MLD desalination capacity tosupply water for Mumbai.
The above picture is an indicator of thepotential of stainless steel in desalinationprojects. This segment offers tremendousopportunities for the stainless steel industryas India has a coastline of 7,517 km andseas are perennial water bodies.
Rajasthan: Two desalination plants atSheelgaon village in Barmer District andSatlana village in Jodhpur, Rajasthan havea capacity of 30,000 liters/day capacity withthe support of BARC in cooperation withDefence Laboratory for providing waterfrom bore well / brackish water sources.
For a Reverse Osmosis (RO) Plant the costof desalination of sea water would bearound 5 paise per litre and for brackishwater desalination the cost works out toaround 2 to 5 paise per litre. India has sofar installed 175 plants, starting with oneat Andaman in 1946. Desalination plantshave proved to be an elixir for places likeLakshadweep, Andaman and some placesin Gujarat, Tamil Nadu and Andhra Pradeshand Rajasthan.

Skid-free Stainless Steel Flooring Now Available in India Highly Durable, Safe and Cost Effective Option
Non-skid steps of stainless steel at amodern abattoir at Ghazipur, New Delhi
Rigidized (embossed) stainless sheetsare produced by rolling a pattern into thesheet with mating rolls which carry the maleand female impressions. This produces asheet which has raised patterns on oneside of the sheet and the back side carriescorresponding dimples. (See images ofmating rolls given on this page).
Rigidized stainless steel sheets with anti-slid patterns are slip-free, enable largenumber of people to move in a limited areawithout losing their balance, assure safetyof workmen and people, and are longlasting. These patterns are attractive andoffer designers a unique material to workwith for providing safety to people wherethere are heavy footfalls and in differentindustrial environments.
Stainless steel has a naturally highresistance to wear, scratching, denting,tearing and corrosion, and is aestheticallypleasing and easy to maintain. Specifically,austenitic stainless steels like 304 arestrongly recommended because of theirability to work-harden on cold forming thepatterns. The raised patterns have a muchhigher hardness than the base material,and therefore, higher wear resistance.This, combined with the high corrosionresistance of the austenitic stainlesssteels, make these grades eminentlysuited for this application.
The life cycle cost of stainless steel anti-skid sheets is minimal compared to othermaterials like carbon steel (wherecorrosion gradually eats away the
protrusions) and aluminium which is softand patterns tend to get erased over aperiod of time. With both these materials,they lose their functionality for which skid-free patterns were provided in the first place,and will have to be replaced every few yearsto be functional.
Applications of skid-free stainless steelsheets are innumerable: The major
application area is slip-free floorings in thetransportation sector for railway coaches,metro coaches, buses etc., and industrialworkplace, ladders and elevator flooringsetc., to ensure safety of people. It can alsobe used for architectural applications inpublic places like foot over bridges andstaircases. These skid-free sheets arealso used in the landing areas ofescalators to help people retain their
balance when abruptly getting off from amoving escalator.
In addition, the nature of stainless steelmakes the material ideal for use in hygienic

Finally, in the automotive sector wherecorrosive chemicals are used in thepainting process, this corrosion resistantslip-free stainless steel flooring showsits mettle by its durability and ensuringworkers’ safety. Other flooring materialscorrode very quickly in automotive paintshop environments.
These patterned sheets are up to 75%stronger than ordinary carbon steel sheetmetal. This results in a down-gaugingwhich allows for less raw material use —saving money and preciousenvironmental resources.

Successful desalination requires amaterial that can resist the aggressivecorrosion caused by seawater andbrine. Utilizing stainless steel to createfresh water further increases thesustainability profile of the desalinationindustry. The durability and minimalmaintenance requirements of stainlesssteel make it a good choiceeconomically. The high-level of recycledcontent and 100% recyclability at the endof its life are the cornerstones ofstainless steel’s environmental profile.High performance stainless steels,including duplex grades, are the perfectchoice for desalination.
Global production of desalinated waterhas increased exponentially since then.Yet worldwide, only 1% of drinking wateris produced by desalination plants,despite the fact that there are more than12,500 plants in over 120 countries. Justunder half (47%) of the commissionedglobal desalination capacity is located inthe Middle East. Considering that almostone quarter of the world’s population livesless than 25 km from the coast, seawaterhas the potential to become one of ourmain sources of fresh water.

confirm that there is a risk of corrosion ifthe wrong stainless grade is used in thehigh-pressure piping.
Neither grade 316L/1.4404 nor 317L/1.4438 possess sufficient corrosionresistance properties. Not even highlyalloyed grades (such as 2205/1.4462and 904L/1.4539) show reliable serviceperformance in this application. However,no corrosion has been reported for newsuper-austenitic stainless grades (suchas S31254/1.4547) which have beenused in more than 30 full-strength SWROplants and several plants using brackishwater with high salinity.
The liberty to choose any unique pattern ofone’s desire is the ultimate freedom andthis is now possible in stainless steel forarchitectural applications.
Architects, interior designers andfabricators would be delighted to know thatetched stainless steel sheets are nowindigenously available at reasonableprices. An infinite variety of exciting anddynamic graphic designs can be createdon stainless steel surfaces by manymethods. One of them is chemical etchingwhere an architect can choose a design ofhis choice and this can be translated on tothe surface of the stainless steel sheet.Etched patterns of your choice can be nowsourced from M/s Fabrinox, ArchitecturalDivision of Dharam Industries, based inDelhi. You also have the choice of selectingthe background in No. 4 (hairline), No. 8(mirror) or Vibratory finishes.
In this process, a protective coating isapplied selectively to the surface.Unprotected areas are chemically etchedto create the design. Etched areas are dullsilver colour and contrast well with thefinish on the unetched surface. The depthof etching is only of the order of a fewmicrons, but it gives a stunning new lookto the stainless steel product’s surface.

Hydrostatic testing of stainless steels
as they are the preferred sites forattachment and growth of microbialcolonies. They also provide traps forchemicals which could concentrate andcause pits.
The likelihood of MIC will also be reducedby:> using full penetration welds; and> purge welding to prevent the formation
of heat tint; or> removing heat tint by grinding or
pickling.
Arc strikes and weld splatter should alsobe ground off and pickled.
2. Use clean waterThe cleanest water available should beused in a hydrostatic test, such asdemineralized, steam condensate ortreated potable water. Untreated or rawwater from dams or bores should beavoided when conducting a hydrostatic testbut, where this is not possible, the watershould be sterilized (eg. by chlorination)before use. If sterilization is not practical,the requirements for short residence timeand subsequent drying of the system areextremely important. The cleaner the water,the less ‘food’ there is for MIC bacteria tolive off and multiply.
It is important to ensure that there is no traceof sediment in the stainless steel systemduring testing to avoid silting, as the wateris normally not circulated during a
hydrostatic test. This may require the testwater to be filtered to ensure it is free ofall undissolved solids. Sediments canprovide the conditions for crevice attack.
3. Draining and dryingThoroughly draining and drying thestainless steel system immediatelyfollowing a hydrostatic test (preferablywithin 24 hours, certainly within 5 days)will almost certainly prevent theoccurrence of MIC.
Horizontal pipelines should be installedin a sloping direction to make them self-draining.
Drying can be achieved by pigging(cleaning with foam or rubber scrapers),followed by blowing dry air through thesystem. Beware of blowing highertemperature moist air through coldpipework unless the air is dried beforebeing introduced to the system. If warmair is used, it should not be from a gasburner as condensation may occur.
Draining and drying of systems followinga hydrostatic test should only bedisregarded when the system is placedinto service immediately following thetest. Partial draining is potentially veryserious as subsequent slow evaporationof even clean residual water can producevery concentrated and aggressivesolutions.
Design engineers frequently specifystainless steel in industrial pipingsystems and tanks for its excellentcorrosion resistance. While stainlesssteel’s unique characteristics make it astandout leader in the durability stakes ofalloys, it is not completely immune tocorrosion.
Premature failures of the stainless steelcan occur due to MicrobiologicallyInfluenced Corrosion (MIC). This corrosionphenomenon usually occurs when rawwater used for hydrostatic pressure testsis not fully removed from the pipework andthere is an extended period beforecommissioning of the equipment. Theresult is localised pitting corrosion attackfrom microbacterial deposits that, in severecases, can cause failure within a fewweeks. MIC is easily prevented usingproper hydrostatic testing techniques.
MIC failures occur by pitting corrosion, oftenat welds, where colonies of bacteria mayform. A number of different bacterialspecies are known to cause the problem,but the detailed mechanism is not known.
Iron utilising bacteria appear to be thedominating microbial species involved withMIC occuring in stainless steel. Anaerobicsulphate-reducing bacteria pose a greaterrisk of instigating or accelerating corrosionoften under a layer of aerobic slime ormicrobial deposits. However others, suchas manganese utilising bacteria (generallyfrom underground waters), have also beendiscovered.
MIC is extremely aggressive and difficult toeliminate once established, so it issurprising and disappointing that there islimited knowledge of MIC within theengineering community. Fortunately, MIC iseasily avoided by using good practicesduring the initial hydrostatic testing.Education and promotion of provenhydrostatic testing practices which preventMIC are vital to minimising its potentialimpact on the stainless steel industry.
Hydrostatic testing practices to eliminateMIC
In order to eliminate MIC, it isrecommended that the following practicesare used.

4. Chloride content and temperatureDuring hydrostatic testing of stainless steelequipment, the chloride content of the testwater must be within the range to which thestainless steel grade is resistant. Figure 1shows the maximum temperatures andchloride contents to which stainless steelsare resistant in water with residual chlorineof about 1 ppm.
The limits shown in Figure 1 may beexceeded provided the contact time of thewater is brief, ie 24-48 hours. If the chloridecontent of the test water is uncertain, thewater should be analyzed.
5. StandardsNACE and API standards for a number ofproducts and installations provideguidelines for hydrostatic testing, includinglimits for water quality and contact times.These standards should be consulted forspecific details for the fabrication in hand.
ConclusionThe benefits of stainless steel’s corrosionresistance are well proven in manyindustrial applications involving pipingsystems, but failures can occur duringhydrostatic testing if care is not taken.Attention to a few simple details will prevent

Stainless Steel Demand Impact of the ‘Chinese miracle’
The real impact of the strong growth rateof stainless steel in China on worldfigures is given in the graph, courtesy,SMR of Austria.
While a 5% growth rate for worldstainless steel is a generally acceptedfigure for the last two decades, a closerscrutiny shows that the exclusion ofrobust growth of stainless steel in Chinafrom world figures would have broughtdown the world growth rate figure to apaltry 1%!!! China has single-handedlylifted the figure to a respectable 5%!!! Itsown growth rate in the last 20 years hasbeen a robust 15%.
The growth rate figures indicated outsidethe field of the graph on the right sideindicate that between 2009 and 2010,when the economies recovered aroundthe world, the growth rates in the rest ofthe world rebounded to 17%, China to20% and the whole world to 18%. Website : www.smr.at
