Abrasion and Impact Resistant, Air Hardened Wear Steel Plate

www.astralloy.com 5

cuTTinGAstralloy-V plate can be cut using traditional methods (oxy, plasma, laser). Plates less than 1" do not need preheating, except in cold or humid climates. Recommended preheating temperature is 250°F (120°C). All plates larger than 1" should be preheated between 400°F and 600°F (205°C and 315°C) in order to avoid premature hardening and cracking.

Preheated areas should be 2" to 3" on each side of the projected cut. We recommend that sufficient time is allowed for preheating so that the temperature can be evenly distributed throughout the plate thickness.

When fabricating gears or sprockets, we recommend the material be stress relieved between 500°F and 600°F (260°C – 315°C). Please contact our technical department for more information.

Shearing is not recommended, as damage to shears may result from Astralloy-V’s higher physical properties.

dRiLLinGAstralloy-V can be drilled with a high speed alloy or hardened bit.

The drill bit must be sharpened so that it has an angle of 140° to 150°, being careful to center the point of union between both sides. The speed for cobalt drill bits should be 8 – 10 SFM and 4 – 6 SFM for high speed drills with a feed of 0.004" per revolution.

To prevent Astralloy-V from work hardening, it is essential to use a positive power feed with abundant soluble lubricant to dissipate heat and lubricate the cutting edges.

FoRMIng And RoLLIngWhen preparing for forming or rolling Astralloy-V, we recommend grinding all edges to round off sharp corners in order to prevent cracking. The minimum ambient temperature should be at least

80°F (25°C) and when cold forming with a hydraulic press, the required minimum internal radius is 24 times the plate thickness. It is recommended that Astralloy-V be cross grained formed, however it is not essential.

One of the greatest advantages of Astralloy-V, compared to other wear steels, is that it can be hot formed and allowed to air cool without losing its original properties. We recommend a minimum temperature of 1600°F (870°C). Hot forming at a temperature below 1450°F (788°C) will result in lower hardness, greater stress levels and reduced abrasion resistance.

WELdIngIn order to weld Astralloy-V, a fresh and dry electrode that is low in Hydrogen is recommended. The E7018 is excellent for normal welding procedures, providing adequate strength with good ductility.

In colder climates, it is always recommended that the plate be preheated to over 300°F (149°C) to remove moisture. The preheating should be applied to areas that will be welded and must uniformly penetrate the full thickness of the plate. In cold temperatures or moving air, insulate the weld to prevent rapid cooling.

Astralloy 8000 is an anti-abrasive, high-quality oil tempered steel. It is characterized by its high performance, with resistance to wear 50% better than water tempered 500 BHN steels. Astralloy 8000 features an innovative concept, based on an original combination of chemical analysis and heat treatment (oil tempering). This combination gives the steel enhanced resistance to abrasion by adding the following features:

* Fine chrome and molybdenum carbides that reinforce the steel’s microstructure.

* Exceptional added 70 BHN work hardening capacity, produced by a metallurgical process called Transformation Induced Plasticity (TRIP).


www.astralloy.com 7

Astralloy 8000cuTTinG* All the classic thermal cutting processes (oxy-plasma-laser) can

be used without preheating for thicknesses up to 1 ½" (the plate temperature must be at least 50°F (10°C). Plates above 1 ½" thick must be preheated to 302°F (150°C) to avoid fractures at the edges. Plasma and laser processes are especially recommended because they increase the precision and appearance of cuts and limit alteration of the affected area.

* Water jet cutting can be used.

* Do not shear thin plates.

MAcHininG* HSSCO high-speed steel bits should be used for drilling

(ex. AR 2.9.1.8 in accordance with ANFOR, M42 in accordance with AISI), with conical shank, long helices, and short insert tips.

* Lubricate with soluble oils diluted to 20%.

* Carbide (K10 or K20) and evenly coated (TIN) bits significantly improve performance when boring multiple holes.

FoRMIng* Cold forming or bending can be performed without difficulty, as

long as the following conditions are observed:

• Edges prepared by grinding to minimize imperfections produced by oxycutting.

• Respect the minimum bend radius. The plate temperature must be at least 50°F (10°C).

* Astralloy 8000 can be hot formed at temperatures of 930° – 1020°F (500° – 550°C), without the need for subsequent heat treating.

WELdIngAstralloy 8000 plates can be welded using any conventional welding technology such as: manual welding with coated electrode, submerged arc welding and gas metal arc welding with flux cored wire. These plates can be welded without preheating, for combined thickness up to 50 mm (2").

Surfaces to be welded must be sufficiently clean, to avoid deterioration by oil, oxide, grease or other contaminant.

EB 450 is a liquid, quenched and tempered, through-hardened, high impact alloy steel with excellent abrasion-resistant properties. Its balanced boron, modified nickel-chrome moly chemistry is ideal for achieving an optimum hardness to toughness ratio. EB 450 boasts a longer wear life due to its through-hardness which is more uniform than what is found in conventional carbon/manganese steels. This quench-hardened material is competitively priced for optimum cost/wear rations. This steel’s resistance to atmospheric corrosion further reduces surface pitting. EB 450 is field proven in extremely abrasive bulk handling installations.


www.astralloy.com 9

BEnEFITS* Higher wear resistance, when compared to conventional steels,

due to its uniform hardness.

* Easy to weld with normal low hydrogen simple techniques.

* May be flame cut with oxyacetylene, plasma or similar methods.

* Cold formable with heavy presses or rolls.

* The high hardness and toughness in combination with its high friction coefficient, reduces maintenance costs.

* EB 450 may be easily cut, welded, machined and cold formed, as required.

The following parameters are provided as a guide:

cuTTinGThe most common cutting methods for EB 450 plate are flame and plasma. For a successful cut, use the procedures and fuel recommended by equipment vendors.

As a precaution, the EB 450 plates must be pre-heated before cutting. Thicknesses of up to 1" require a temperature of 250°F (120°C) and larger thicknesses require a temperature of 300°F (140°C).

Normally, for anti-abrasive applications, these cut methods provide a precision range of +/- 1/8" along the length and width. For applications where stricter tolerances are required, please consult our technical department.

dRiLLinGEB 450 requires slow speeds for better drilling. Feed speed must be maintained constant.

For optimum drilling results, we recommend using low rpm speeds for tools, short stem bits and generous cutting lubrication. Bits with carbide inserts provide longer life; however, a good quality high speed bit is enough.

To re-sharpen the tool, a point angle between 135° and 150° and negative rake is recommended. Speed must be between 10 – 20 SFPM (surface feet per minute). For example, when drilling 3/4", the feeding must be between 0.004" and 0.008" per revolution.

MAnUFACTURIngDespite the high toughness of EB 450, it is possible to bend it with a hydraulic press and cold form it. We recommend bending it transverse to the rolling direction marked on each plate.

The internal minimum radius for forming EB 450 is:

* When bending transverse to the rolling direction, the minimum radius is 6 times the thickness of the plate.

* When bending parallel to the rolling direction, the minimum radius is 12 times the thickness of the plate.

* To cold bend the EB 450 plate to 90°, form in gradual steps without exceeding the recommended minimum radius.

WELdIngThe EB 450 is readily weldable by following some basic welding guidelines.

To prevent cracking during the welding process, the following three areas should be controlled:

1. Eliminate hydrogen pick-up in the weld metal during welding.

2. Minimize stress in the weld joint.

3. Use proper preheat and interpass temperatures and avoid rapid cooling of the weld area following welding.

While welding the EB 450 product, we recommend the use of skip welding and backstep welding procedures, as well as minimizing the heat input.

AstraWear 500F

AstraWear 500F is a water tempered martensitic steel, with 500 BHN (51.5 HRC), typical hardness and resistant to wear from very severe abrasion. Its mechanical properties, high wear resistance, hardness, and strength make AstraWear 500F steel ideal for use in applications requiring resistance to sliding abrasion and where 400 BHN steels do not provide a long enough service life.

Compared with conventional steels, like A572-50 (S355), AstraWear 500F offers real improvement in equipment lifespans, of up to 5 times, and consequently allows for significant reductions in design thickness.

AstraWear 500F steel is especially suited for applications in quarries, construction, mines, cement plants, and the iron and steel industry, among others.Note: The data contained in this document is accurate at time of printing, and intended for use as a general guide. *Typical maximum values.

AstraWear 450F

AstraWear 450F is a water tempered martensitic steel, with typical hardness of 450 BHN, which offers a real response to wear from abrasion. Its resistance, high hardness, and yield strength make it highly resistant to plastic deformation and wear from scraping and impact.

AstraWear 450F shows resistance to wear typically equal to 4 times and any yield strength 3 times greater than those of a A572-50 (S355) steel. Using AstraWear 450F represents a major improvement in terms of service life and lightening of equipment by reducing thickness. AstraWear 450F is easy to process, has good welding capacity and good bendability, considering its outstanding mechanical properties.

This steel is especially suited for applications in quarries, construction, mines, cement plants, and the iron and steel industry, among others.

AstraWear 450F is a grade especially suited for manufacturing truck bodies.

Astralloy Trip-L-Tuff

Chemical Composition of overlay* – % Weight

c Mn si cr Fe

6.0 3.0 1.0 28.0 Balance

ASTRALLoY TRIP-L-TUFF PLATEAdvantages over other wear materialsMetal: Astralloy Trip-L-Tuff has significant advantages in some areas over AR products. Astralloy Trip-L-Tuff has the yield strength of mild steel, making it easy to bend. It has no memory, so it holds shape. It is not heat treated, so welding does not affect its properties. It can be formed to a radius as small as 3" (on thin plate.) With the relaxed condition of the Astralloy Trip-L-Tuff base material, the forming will not create cracks on the outer bend, and with the consistency of the Astralloy Trip-L-Tuff weld material,no spalling or breakage will occur on the inner surface.

Base material is ASTM A 36 structural steel. The overlay consists of predominantly hard chromium carbides in a tough iron-base matrix. Nominal hardness is 555 – 653; microhardness of chromium carbide is 1800 VPH (70 – 75 Rockwell C converted.)

Astralloy Trip-L-Tuff combines a super hard, tough surface on a ductile and weldable mild steel backing to provide the ultimate wear-resistant plate. Superior metallurgical properties achieved In a highly controlled process utilizing the proper blend of elements result in an overlay with an abundance of ultra-hard chromium carbide particles evenly distributed in an extremely hard, tough matrix. These carbides are 3 to 4 times as hard as steel as measured in microhardness tests.

The combination of the hard overlay with a structural steel backing facilitates ready adaptation to a variety of field wear situations. The composite plate can be moderately formed and readily welded or bolted in place.

Astralloy Trip-L-Tuff will typically exhibit stress relief cracks in the overlay surface. These cracks are an inherent feature of hard-facing and develop as the overlay cools following deposition, at 5/8" to 2" spacing transverse to the weld bead. They are confined to the overlay and do not penetrate into the base plate nor propagate in service.

ASTRALLoY TRIP-L-TUFF PIPE And ELBoWSThe overlay applied to Astralloy Trip-L-Tuff pipe has the same chemistry and properties as the plate overlay. It is applied to the inside or outside of the pipe, as required. All sizes are available down to 2" inside diameter.

Applications and UsesAstralloy Trip-L-Tuff pipe is used primarily for wear due to friction. With plate, this could be from coal, rock, or gravel moving through or across a chute, liner, cyclone, sizing screen, dozier blade, breaker plate, etc. With the pipe, applications may include slurry, coke, coal dust, etc.

Advantages over other wear materialsCeramic: Astralloy Trip-L-Tuff also has certain advantages over ceramics. Given the high price of ceramics, cost is a major factor. Installation costs are also a factor due to the thickness and attachment procedures necessary for the fragile ceramic.

Chipping is another factor inherent in ceramic. Ceramic cannot handle impact whatsoever, whereas the Astralloy Trip-L-Tuff will handle moderate to (in some cases) severe impact. Attachment failure is yet another drawback to glued on ceramic pieces. In piping, Astralloy Trip-L-Tuff is particularly better suited than ceramic. Due to the thickness of ceramics, special “odd-ball” mechanical tubing and elbow sizes, as well as flanges must be located and purchased, or fabricated. Astralloy Trip-L–Tuff can be applied to every pipe or elbow size, from a minimum of 2" inside diameter. Flanges, couplings, and connections are no longer a concern.


Chromium Carbide overlay Wear Plate, Pipe and Elbows


Astralloy Trip-L-TuffcuTTinG* Plasma arc cutting is recommended for making holes, cutting

shapes, or beveling. Carbon air-arc method may be used for gouging or non-precision holes. Cut from the mild steel side.

FoRMIng* Astralloy Trip-L-Tuff can be formed by conventional shop

procedures. The overlay side must be on the inside of any formed radii. Protect bending rolls with 3/16" plate over hard-faced sides.

MAcHininG* Electrical discharge machining (EDM) methods are used for

precision machining of Astralloy Trip-L-Tuff. Conventional cutting tools, cermeis, and carbide will not cut Astralloy Trip-L-Tuff.

* The hard chromium carbide overlay can be ground using a hard grit wheel having a soft bond.

WELdIng* A hard-facing pass of Hardalloy 58 (or equal) restores a wear

surface such as exposed areas from piercing or joining.

* Type 312 stainless is recommended for an intermediate pass between hard-facing and base plate steel.

coated, stainless steel electrodes can be used, but are more expensive than manganese steel filler metals.

* For flux-cored arc welding with an auxiliary gas, the best results are obtained when the shielding gas is 100% argon.

Storage of Electrodes* Purchase low hydrogen electrodes in hermetically sealed

containers. Large containers may have electrodes with too much moisture which can result in underbead cracking. Electrodes which are exposed to air for over one hour should be baked in a 500°F ventilated oven for two hours.

* Use smallest applicable rod diameter to allow for full penetration.

This grade is supplied in the quenched and

annealed condition.

Hardness in Service 500 to 650 BHn

Should only be used in wear situations

where high impact and/or gouging abrasion

will develop a very high surface hardness.

Rol-MandRiLLinG* Rol-Man can be successfully drilled with “M-Style Hardsteel

Drills”. Hardsteel drilling is friction drilling, not twist drilling. The process involves heating the steel under the drill point, not just cutting it cold.

* Maintain selected speed and constant feed pressure.

* Use rust-inhibited water coolant to minimize drill heating.

* Because Rol-Man is a work hardening steel, conventional drill bits tend to harden rather than cut the steel.

* Set the spindle speed according to the table below:

MAcHininG* On a lathe, use carbide tools, 90 – 100 SFM, feed at .012" per

revolution for roughing, and .008" revolution for finishing.

* For milling, use carbide tools, 50 SFM, with a .004- chip load per insert per revolution.

cuTTinG* Plasma or laser cutting works well. Oxyacetylene cutting gives a

poor edge.

* Shearing or punching on sturdy machines with property sharpened edges is possible. However, this will work harden the immediate area.

FoRMIng* Rol-Man forms much the same as mild steel of comparable

hardness.

* There is little work hardening in bending or rolling.

* Any previously work hardened areas, such as sheared edges or drilled holes, should be ground away before bending stresses are applied.

* A light beveling of edges is helpful. Preheating is unnecessary for cold forming operations.

Astralloy-V

Astralloy-V round bars have the same chemistry, uniform toughness and hardness as plate, from surface to core. Astralloy-V’s ultra-fine grain structure, free of massive carbide particles due to its lower carbon content, provides better machinability at its higher strength/hardness level than quenched and tempered alloys.

AdVAnTAgES* Maintains its toughness and hardness without brittleness at temperatures of up to -75°F.

* Uniform hardness throughout the mass (340 BHN) to resist abrasion.

* Hardenability in the range of 550 BHN by impact or sliding action, without deformation or brittleness.

* Astralloy-V’s small oxide surface quickly disappears, exposing a slick, durable surface.

* Can be hot worked and allowed to air cool without loss of hardness or toughness and without warpage problems.

MAcHininGFor the best continuous machining, we recommend using disposable negative rake, mechanically clamped tungsten carbide inserts and contoured grinders.

For an excellent finish, speeds should be 180 to 270 SFM. A generous and continuous lubricant/coolant bath will prolong tool life.

For better metal removal, the cutting depth should exceed the feed rate by a factor of 10.

MiLLinGFor optimum metal removal in interrupted machining, use negative rake, mechanically clamped tungsten carbide inserts. The generally recommended feed rate is 0.003" per tooth. The total cutting rate is equal to 0.003" times the number of inserts in the cutter x rpm. Uniform feed distribution requires the use of precision inserts.

At a hardness of 350 BHN, 150 surface feet per minute is reasonable. Slower rates for greater hardness and higher rates for lesser hardness.

WELdIngIn order to weld Astralloy-V, a fresh and dry electrode that is low in Hydrogen is recommended. The E7018 is excellent for normal welding procedures, providing adequate strength with good ductility.

In colder climates, it is always recommended that the plate be preheated to over 300°F to remove moisture. The preheating should be applied to areas that will be welded and must uniformly penetrate the full thickness of the plate. In cold temperatures or moving air, insulate the weld to prevent rapid cooling.

In today’s world of hit and run tactics by vandals, thieves and terrorists; solid, reliable materials must be used to defeat these threats and to protect both person and property. BP6:33 is expressly designed for this purpose. With its unique metallurgical characteristics, it can be cut cold, or hot formed, and welded using normal shop practices and still retain its high hardness, without loss of ballistic properties. BP6:33 will defeat a wide range of commercial and military threats such as handguns, rifles, automatic weapons, and fragmentation.

BP6:33 is Astralloy Steel Products’ proprietary grade of ballistic armor plate. BP6:33 is independently tested to meet the National Institute of Justice Standards 0101.03, 0108.03 and is listed with the Underwriters Laboratories (Standard 752). Astralloy Steel Products’ quality control standards meet the requirements specified in Mil-A-45208.

FoRMIngBP6:33 can be formed using either a brake press or by roll forming. Because of its high toughness, BP6:33 forms to shapes not possible with other high strength steel alloys, even those with hardnesses as low as 321 BHN. Although modern melting practices minimize directional differences in the mechanical properties of BP6:33 plate, cross grain forming is preferred, especially when cold forming to tight radii. During cold forming, allow 4½ times the brake press power required for forming the same thickness and size of mild steel. Also, when forming cold, an allowance should be made for “spring back”.

Forming should be done hot (1600°F minimum) if the bend radius is less than approximately 20 to 24 times the thickness of the plate, or if the forming equipment does not have adequate power to overcome 172,000 psi yield strength. Unlike quenched and tempered alloy steels, BP6:33 can be hot formed without loss of hardness and allowed to air cool. Provided the hot formed parts are cooled with free air circulation after forming, they will not only regain their original high hardness, but also retain high toughness and strength.

WELdABILITYAs with other high strength steels, welding of BP6:33 requires special considerations. When welded with proper techniques, BP6:33 provides significant advantages over other ballistic steels. Because of its’ air-hardened ability, the hardness of the heat affected zone is similar to that of the base metal, virtually eliminating concern for soft zones next to the weld.

APPLicATionsSome of the many applications where BP6:33 has been successfully used are:

* Add-On Armor Packages * Embassy Installations

* Armored Cars/Limos * Firing Ranges/Targets

* Armored Personnel Carriers * Guard Towers

* Armored Railroad Cars * HMMWV Countermine Kits

* Armored Trucks/Trailers * Safe Rooms

* Bank Counters/Cages/Boxes * Security Vans

* Body Armor Vest Inserts * Security/Guard Buildings

* Bullet Resistant Shields * Nuclear Installations

* Computer/Instrument Rooms * Up-Armored HMMWVs
