Production Process of ShapesISO 9001 Certified Quality
As the worlds leading manufacturer ofsteel beams, ArcelorMittal offers engineersand fabricators innovative, competitiveand sustainable solutions that are fully
compatible with the use of other materials.Our electrical steelworks comply withthe strictest environmental criteria, and
our products meet all of the constructionsectors technological requirements. ArcelorMittal structural shapes
are produced in modern minimills using
100 percent scrap as raw material. Thebelow schematic diagram shows theproduction process, which consists of
three main operations: melting, casting
and rolling. To begin production, thescrap material is melted in highly efficientand environmentally friendly electric arc
furnaces. The steel is then refined in a ladlefurnace, and its temperature and chemistryis regulated before the casting process. In a
continuous castor, the steel is solidified to a
semi-finished product called a beam blAfter casting, the beam blanks are direreheated to rolling temperature or stoc
for later rolling. The rolling mills typically

HISTAR/ ASTM A913 in the Codes
AISC 360-10 Specification for Structural Steel BuildingsASTM A913 has been an approved specification with AISC sincethe publication of LRFD Specification for Structural Steel Buildings
in 1999. The approval came in a letter ballot of the SpecificationsCommittee in July 1995 and was confirmed at its meeting in
November 1995. ASTM A913 (including all grades) is still included
as an approved specification under A3.1a of the Specification forStructural Steel Buildings dated June 22, 2010. This includes both
ASD and LRFD design methods.
AISC 341-10 Seismic Provisions for Structural SteelBuildingsSection A3.1, the Seismic Provisions for Structural Steel Buildings
allows ASTM A913 Grades 50 and 65 for use in seismic forceresisting systems and states that the specified minimum yield stress
of structural steel shall not exceed 65 ksi (450 MPa) for columnsin systems defined in Sections E3, E4, G3, H1, H2 and H3, and forcolumns in all systems in Chapter F. ASTM A913 Grade 70 can be
used at the engineers discretion.
AWS D1.1 Structural Welding CodeAWS D1.1 (2010) lists ASTM A913 Grades 50 and 65 asprequalified steels. In accordance with Table 3.2 of the structuralwelding code AWS D1.1, ASTM A913 Grades 50 and 65 are
weldable without preheating (minimum 32F) when welded with lowhydrogen electrodes (H8).
FEMA 350 and 353FEMA-350 (July 2000) Recommended Seismic Design Criteria forNew Steel Moment-Frame Buildings approves and recommends the
use of ASTM A913 Grades (Chapter 2.6.1). FEMA-353 (July 2000)
Recommended Specifications and Quality Assurance Guidelinesfor Steel Moment-Frame Construction for Seismic Applicationsapproves and recommends the use of ASTM A913 Grades (Chapter
2.1c)
IBC 2012By reference to AISC 360-10, the use of ASTM A913 steel is
approved by the 2012 IBC, Section 2205.1

Benefits of HISTAR/ ASTM A913 Steel
WeldabilityASTM A913 Grades 50, 65 and 70 havea guaranteed maximum carbon equivalent
(CE%) of 0.38, 0.43 and 0.45 percents. Inmost cases, these low maximum CE% values
allow A913 grades to be welded without
preheating. In accordance with AWS D1.1, all shapes
in A913 Grades 50 and 65 are weldablewithout preheating (minimum 32F) when
welded with low hydrogen electrodes (H8).For welding large material thicknesses in
highly restrained conditions, preheating maybe necessary. For base metal temperaturesbelow 32F, AWS D1.1 requires preheating
to 70F. AWS D1.1 also specifies that ifelectrodes have a higher level of hydrogen
than 8ml/100g, A913 Grades 50 and 65 areto be welded like ASTM A572 Grades 50 and
65, with preheating.
ToughnessThe guaranteed minimum toughness of all ASTM A913 steel gradesis 40 ft-lbs at 70F at the flange location. Upon agreement material
can be supplied with Charpy V-Notch tests down to -58F atadditional cost.

Applications of HISTAR/ ASTM A913 Steel
Strong Column - Weak BeamConcept for Seismic Resisting Moment Frame StructuresIn 1989, ArcelorMittal was awarded apatent for the Reduced Beam Section(RBS) or dog-bone connection. This
connection is easily performed in the
fabrication shop and results in the removalof a portion of the beams flange materialat its connection to supports. Design of
such a connection became more criticalafter the 1994 Northridge earthquake,which exposed several seismic design
deficiencies. A number of steel moment-frame buildings experienced brittle fractures
of beam-to-column connections as a resultof the earthquake. Upon study, the SAC
Joint Venture, under contract by FEMA,developed the strong column weak beamdesign concept. When used in conjunction
with ArcelorMittals RBS connection, which
was released from patent in 1995, thisdesign concept can facilitate a shift of theplastic deformation from the column to
the beam during an earthquake, therebypreventing the connection between thecolumn and the beam from experiencing
inelastic deformations. The method wassuccessfully tested by AISC and was included
in the FEMA 350 and 353 documents. As a result of the construction industrys
shift away from ASTM A36 to Grade 5steel, it is often necessary to use highestrength steel in the design of columns
Using ASTM A913 Grades 65 or 70 fo
column shapes and A913 Grade 50 (wa maximum yield point of 65 ksi) forbeams, coupled with the RBS, offers th
most economical solution to seismic deavailable today. In addition, replacing Awith higher yield A913 can lower mate
weight and cost, strengthen connectioreduce or eliminate stiffeners in the pan
zone and reduce or eliminate the need doubler plates.

Applications of HISTAR/ ASTM A913 Steel
When it is necessary to preheat the weld area
A major advantage of ASTM A913 versus A992 or A572 is that
A913 Grades 50 and 65 generally do not need to be preheatedbefore welding. Since ArcelorMittal does not charge a premium
for A913 steel versus A992 or A572, you can achieve significantsavings on welding costs. Even when a project is not suited for
A913 Grades 65 or 70 material, A913 Grade 50 still offers the nopreheat welding advantage.

When deflection is not a concern
If the design of an element is governed by a yield problem, increasing the yield of this element normally enables the designer to choose smaller size, thereby reducing the weight. However, if the design is governed by deflection or a vibration problem the design depends o
the stiffness or the inertia and not on the yield. The weight savings for column applications have historically been between 15 and 25 percent. For long-span trusses the savings a
often as high as 30 percent. In addition to steel weight savings, the fabrication, transportation, handling, erection and foundation costs structure are also reduced. Particularly for heavy shapes the welding time and costs are reduced as thinner members reduce the weld vo
and ASTM A913 grades generally do not need to be preheated before welding allowing considerable savings of time and energy.

Applications of HISTAR/ ASTM A913 Steel
Gravity Columns for High-Rise BuildingsWhen design is not governed by drift or vibration problems, the useof ASTM A913 Grades 65 and 70 in gravity columns with normal
buckling lengths (typically less than 15 ft) enables the engineerto reduce the weight and the cost of their structures. The steel
weight of the columns can typically be reduced by 10 to 25 percent.
Recent projects where A913 Grade 65 was used for gravity columnsinclude One World Trade Center in New York and the Shanghai World
Financial Center in China.
Long-Span TrussesThe best use of A913 Grades 65 or 70 is in tension members, suchas the typical bottom chord of a truss, or in compression memberswith short buckling lengths. The use of A913 Grades 65 or 70 in
trusses can generally result in a 25 percent reduction in weightcompared to Grade 50 steel. This reduction in weight is a function
of the total span-length and the importance of dead loads on thedesign. High-yield A913 grades have resulted in savings on several
high-profile stadium projects with retractable roofs, high-risebuildings featuring long-span transfer trusses and hangar facilitieswith roofs supported by trusses, such as the Boeing Assembly Hall,
which features a 354-foot-long spanning roof and saw a weightreduction of 28 percent when A913 Grade 65 was used in lieu of
Grade 50 steel.
Seismic Design / Moment Frames / Strong Column -Weak BeamThe use of ASTM A913 steel allows the engineer to design a
moment-frame structure with the economical strong column weak beam concept commonly used on the West Coast. A913Grade 65 is the only steel grade with a yield point above 50 ksi that
is included in the AISC Seismic Provisions for use in the columns ofmoment-frame structures in seismic zones.
Bridge GirdersWhen the design of a bridge is not governed by a deflection problem,usually the case for light loads and/or for short spans, the use of
A913 Grades 65 or 70 enables engineers to reduce the weight andthe cost of the structure. In addition, the use of A913 Grades 50
and 65 make it possible for the fabricator to weld the steel withoutpreheating (minimum 32F with low-hydrogen electrodes).

360-10 Specification for Structural SteelBuildings, AISC 341-10 Seismic Provisions
for Structural Steel Buildings, IBC and FEMA.
Why is toughness of A913 superiorto hot-rolled steel?The in-line thermal process QST results
in a very fine-grain material, showing asuperior toughness when compared withconventional hot-rolled steel.
Which Charpy V-Notch toughnessrequirements can A913 meet?Based on impact tests per ASTM A673, a
minimum average CVN value of 40 ft-lbfat 70F is a general requirement of A913.Upon request a minimum average CVN value
of 20 ft-lbf at 70F in the alternate corelocation (S30 per ASTM A6) is also available.
In addition, A913 can be supplied with CVNvalues down to -58F for low temperatureapplications. Other test temperatures and
impact values are available upon agreement.
What is the ductility of A913 Grade65 and 70?A913 Grades 65 and 70 are very ductile
steels, despite their distinctively higheryield strengths compared to typical 50 ksi
steel. Based on tension tests per ASTM370, the minimum elongation percentagefor A913 Grade 65 is 15 percent for an
8-inch specimen and 17 percent for a2-inch specimen. The minimum elongation
percentage for A913 Grade 70 is 14 percentfor an 8-inch specimen and 16 percent
for a 2-inch specimen. These elongationvalues are considered largely sufficient toensure the formation of a plastic hinge, if
appropriately designed and detailed.

ASTM A913 Steel Frequently Asked Questions (FAQs)
5/26/2018 Arcelor Mittal American Structural Shapes
13/1611 | Structural Shapes
What is the fire resistance of A913?Tests have demonstrated that the fireresistance of A913 is the same as that of
conventional hot-rolled structural grades.
What about residual stresses in
A913?A913 has lower residual stresses relative to
its yield strength than A36.
What is the corrosion resistance ofA913?The corrosion resistance of A913 shapes isthe same as that of conventional hot-rolled
structural grades.
Which specification should be usedwhen welding A913?
A913 offers good weldability for manualand automatic processes provided thegeneral rules for welding are followed.
Table 3.2 of AWS D1.1 indicates that A913grades 50 and 65 are weldable without
preheating when the product temperatureis above 32F and when using a low-hydrogen electrode (H8). This advantage
is due to its low Carbon Equivalent (CE%)values compared to conventional hot-
rolled structural steel. As with other steelgrades, highly restrained conditions and
large material thickness may require some
preheating. In most cases highly restrainedconditions can be avoided by choosing
adequate weld sequencing. Selection ofstrength level of consumables is shown
in AWS D1.1 Table 2.3. Prequalifiedcombinations of base metal and filler metal
for matching strength are listed in AWS D1.1Table 3.1.
Can A913 be used in combinationwith other grades?Yes. When welding A913 to A992 orA36, preheating is typically needed forthe A992 or A36 material but not for the
A913 material. Preheating the A913 has no
detrimental effect.
Can A913 be galvanized?Yes. A913 is typically delivered with aSilicon content ranging between 0.15 and
0.25 percent, and as such is suitable to begalvanized.
What about flame cutting shapes inA913?A913 can be cut with a torch using the sameprocedures applied to any structural steel.
Due to the low carbon equivalent of A913,preheating in order to prevent crackingis generally not necessary for product
temperatures above 32F.
What about flame straighteningshapes in A913?As with any structural steel it is possible to
eliminate deformations or to give a membera special shape by flame straightening.
For local reheating of the entire materialthickness the maximum flame straightening
temperature is 1200F. For local superficial
reheating of the surface only, the maximumflame straightening temperature is 1650F.
What about machining shapes inA913?A913 can be machined under the sameconditions as grades with the same lev
yield strength. Drilling and cutting tests
A913 showed no difference in tool wea
than for other structural grades of the strength level. In fact using higher stresteel allows the designer to reduce the
size (thickness) of the material and thureduce the machining time.
What about stress relieving ofshapes in A913?Stress relieving post weld heat treatme(PWHT) may be necessary when the laof the structure and/or the expected s
condition after welding requires a redu
of the residual stresses. If stress relievirequired, it should be performed in the manner as for any structural steel grad
temperature should range between 98and 1080F. The holding time should btwo minutes per mm (1/25") of mater
thickness, but not less than 30 minutesnot more than 90 minutes.
Which sections can bedelivered according to A6 S30(Supplement 2)?The following profiles are available with
