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

one break-down stand and two or threuniversal rolling stands to shape the proto its final dimensions. Finally, the profil

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.

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.




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).

ASTM A913 Steel Frequently Asked Questions (FAQs)



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.
