1 | Structural Shapes

ArcelorMittal is the world’s leading steel and mining company and the largest importer of wide-flange beams in the United States – a market which it has served for more than 80 years . Our total steel production

of 97 .2-million tons in 2012, represents six percent of world steel output and ranks us first in the world for steel production . ArcelorMittal employs 245,000 individuals across 60 countries, including more than 36,000 in North America . As the leading global provider of structural steel shapes, ArcelorMittal produces steel that is used in buildings around the world, from tall towers to petrol refineries, from airports to railway stations and from shopping malls to residential

houses . Our annual sales of structural shapes exceed five and a half million tons and make us the European leader in the production of structural and piling sections . Our mill in Differdange, Luxembourg rolled the first parallel wide flange shape in the world in 1902 and the first 40-inch deep beam in 1911 . In 1979, we introduced Tailor-Made beams (WTM), which were praised by both structural engineers and fabricators as a cost effective alternative to built-up sections and concrete . Today, ArcelorMittal offers the largest range of shapes in the world including W14 x 16 columns weighing up to 873 lbs/ft and several W44 x 16 sections .

In 1990, ArcelorMittal introduced high-strength, low-alloy HISTAR steel to the world market . Initially available in only Grades 50 and 65, the range of HISTAR was expanded in 2011 to include Grade 70 . Conforming to ASTM A913 in the United States, HISTAR steel Grades 50 and 65 are approved by all major United States structural design and fabrication codes: AISC (ASD, LRFD and Seismic); IBC; AWS; and FEMA/SAC . The sections produced by ArcelorMittal using A913 steel have superior characteristics, including high yield strengths, excellent toughness and outstanding weldability . In addition, they are available without paying a price premium over our A992 or A572/50 steels . A913 steel is perfect for gravity columns, long span trusses, “strong column / weak beam” seismic designs and short or medium spans where deflection is not a concern . Later in this program, you will find an extensive list of prominent projects on which A913 steel has been specified .

Production Process of ShapesISO 9001 Certified Quality

As the world’s leading manufacturer of steel beams, ArcelorMittal offers engineers and fabricators innovative, competitive and sustainable solutions that are fully compatible with the use of other materials . Our electrical steelworks comply with the strictest environmental criteria, and our products meet all of the construction sector’s technological requirements . ArcelorMittal structural shapes are produced in modern minimills using

100 percent scrap as raw material . The below schematic diagram shows the production process, which consists of three main operations: melting, casting and rolling . To begin production, the scrap material is melted in highly efficient and environmentally friendly electric arc furnaces . The steel is then refined in a ladle furnace, and its temperature and chemistry is regulated before the casting process . In a continuous castor, the steel is solidified to a

semi-finished product called a beam blank . After casting, the beam blanks are directly reheated to rolling temperature or stocked for later rolling . The rolling mills typically have one break-down stand and two or three universal rolling stands to shape the product to its final dimensions . Finally, the profiles are cooled, cut to length, inspected, marked and bundled before shipment to our customers .

HISTAR® / ASTM A913 in the Codes

AISC 360-10 Specification for Structural Steel BuildingsASTM A913 has been an approved specification with AISC since the publication of LRFD Specification for Structural Steel Buildings in 1999 . The approval came in a letter ballot of the Specifications Committee 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 for Structural Steel Buildings dated June 22, 2010 . This includes both ASD and LRFD design methods .

AISC 341-10 Seismic Provisions for Structural Steel BuildingsSection A3 .1, the Seismic Provisions for Structural Steel Buildings allows ASTM A913 Grades 50 and 65 for use in seismic force resisting systems and states that the “specified minimum yield stress of structural steel shall not exceed 65 ksi (450 MPa) for columns in systems defined in Sections E3, E4, G3, H1, H2 and H3, and for columns in all systems in Chapter F .” ASTM A913 Grade 70 can be used at the engineer’s discretion .

AWS D1.1 – Structural Welding CodeAWS D1 .1 (2010) lists ASTM A913 Grades 50 and 65 as prequalified steels . In accordance with Table 3 .2 of the structural welding code AWS D1 .1, ASTM A913 Grades 50 and 65 are weldable without preheating (minimum 32ºF) when welded with low hydrogen electrodes (H8) .

FEMA 350 and 353FEMA-350 (July 2000) “Recommended Seismic Design Criteria for New 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 Guidelines for Steel Moment-Frame Construction for Seismic Applications” approves 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 have a guaranteed maximum carbon equivalent (CE%) of 0 .38, 0 .43 and 0 .45 percents . In most 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 weldable without preheating (minimum 32°F) when welded with low hydrogen electrodes (H8) . For welding large material thicknesses in highly restrained conditions, preheating may be necessary . For base metal temperatures below 32°F, AWS D1 .1 requires preheating to 70°F . AWS D1 .1 also specifies that if electrodes have a higher level of hydrogen than 8ml/100g, A913 Grades 50 and 65 are to be welded like ASTM A572 Grades 50 and 65, with preheating .

ToughnessThe guaranteed minimum toughness of all ASTM A913 steel grades is 40 ft-lbs at 70°F at the flange location . Upon agreement material can be supplied with Charpy V-Notch tests down to -58°F at additional cost .

Applications of HISTAR® / ASTM A913 Steel

‘Strong Column - Weak Beam’Concept for Seismic Resisting Moment Frame StructuresIn 1989, ArcelorMittal was awarded a patent for the Reduced Beam Section (RBS) or “dog-bone” connection . This connection is easily performed in the fabrication shop and results in the removal of a portion of the beam’s flange material at its connection to supports . Design of such a connection became more critical after 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 result of the earthquake . Upon study, the SAC

Joint Venture, under contract by FEMA, developed the “strong column – weak beam” design concept . When used in conjunction with ArcelorMittal’s RBS connection, which was released from patent in 1995, this design concept can facilitate a shift of the plastic deformation from the column to the beam during an earthquake, thereby preventing the connection between the column and the beam from experiencing inelastic deformations . The method was successfully tested by AISC and was included in the FEMA 350 and 353 documents . As a result of the construction industry’s

shift away from ASTM A36 to Grade 50 steel, it is often necessary to use higher strength steel in the design of columns . Using ASTM A913 Grades 65 or 70 for column shapes and A913 Grade 50 (with a maximum yield point of 65 ksi) for beams, coupled with the RBS, offers the most economical solution to seismic design available today . In addition, replacing A992 with higher yield A913 can lower material weight and cost, strengthen connections, reduce or eliminate stiffeners in the panel zone and reduce or eliminate the need for 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 preheated before welding . Since ArcelorMittal does not charge a premium for A913 steel versus A992 or A572, you can achieve significant savings on welding costs . Even when a project is not suited for A913 Grades 65 or 70 material, A913 Grade 50 still offers the “no preheat” 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 a smaller size, thereby reducing the weight . However, if the design is governed by deflection or a vibration problem the design depends only on 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 are often as high as 30 percent . In addition to steel weight savings, the fabrication, transportation, handling, erection and foundation costs of the structure are also reduced . Particularly for heavy shapes the welding time and costs are reduced as thinner members reduce the weld volume 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 use of ASTM A913 Grades 65 and 70 in gravity columns with normal buckling lengths (typically less than 15 ft) enables the engineer to 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 columns include 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, such as the typical bottom chord of a truss, or in compression members with short buckling lengths . The use of A913 Grades 65 or 70 in trusses can generally result in a 25 percent reduction in weight compared to Grade 50 steel . This reduction in weight is a function of the total span-length and the importance of dead loads on the design . High-yield A913 grades have resulted in savings on several high-profile stadium projects with retractable roofs, high-rise buildings featuring long-span transfer trusses and hangar facilities with roofs supported by trusses, such as the Boeing Assembly Hall, which features a 354-foot-long spanning roof and saw a weight reduction of 28 percent when A913 Grade 65 was used in lieu of Grade 50 steel .

Seismic Design / Moment Frames / “Strong Column - Weak Beam’’The 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 . A913 Grade 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 of moment-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 and the cost of the structure . In addition, the use of A913 Grades 50 and 65 make it possible for the fabricator to weld the steel without preheating (minimum 32°F with low-hydrogen electrodes) .

What are the design rules for columns, beams and connections in A913A913 is a referenced standard in AISC 360-10 Specification for Structural Steel Buildings, AISC 341-10 Seismic Provisions for Structural Steel Buildings, IBC and FEMA .

Why is toughness of A913 superior to hot-rolled steel?The in-line thermal process QST results in a very fine-grain material, showing a superior toughness when compared with conventional hot-rolled steel .

Which Charpy V-Notch toughness requirements can A913 meet?Based on impact tests per ASTM A673, a minimum average CVN value of 40 ft-lbf at 70°F is a general requirement of A913 . Upon request a minimum average CVN value of 20 ft-lbf at 70°F in the alternate core location (S30 per ASTM A6) is also available . In addition, A913 can be supplied with CVN values down to -58°F for low temperature applications . Other test temperatures and impact values are available upon agreement .

What is the ductility of A913 Grade 65 and 70?A913 Grades 65 and 70 are very ductile steels, despite their distinctively higher yield strengths compared to typical 50 ksi steel . Based on tension tests per ASTM 370, the minimum elongation percentage for A913 Grade 65 is 15 percent for an 8-inch specimen and 17 percent for a 2-inch specimen . The minimum elongation percentage for A913 Grade 70 is 14 percent for an 8-inch specimen and 16 percent for a 2-inch specimen . These elongation values are considered largely sufficient to ensure the formation of a plastic hinge, if appropriately designed and detailed .

For A913 Grade 50, what is the maximum YS and YS/TS ratio?For seismic applications, A913 Grade 50 is available with maximum yield strength (YS) of 65 ksi and maximum yield strength to tensile strength ratio (YS/TS) of 0 .85 . These additional requirements are available upon request at no additional cost (S75 per ASTM A913) .

A913 Grades 50 and 65 are referenced standards in the AISC Seismic Provisions and are recommended in the FEMA 350 and 353 Seismic Specifications . It is ideally suited for seismic applications .

What is the fatigue behavior of A913?Full-scale tests of A913 shapes showed a fatigue behavior exceeding the requirements of the codes for conventional steels . Hence, A913 is also particularly suited for bridge applications .

ASTM A913 Steel Frequently Asked Questions (FAQs)


What is the fire resistance of A913?Tests have demonstrated that the fire resistance 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 of A913?The corrosion resistance of A913 shapes is the same as that of conventional hot-rolled structural grades .

Which specification should be used when welding A913?A913 offers good weldability for manual and automatic processes provided the general rules for welding are followed . Table 3 .2 of AWS D1 .1 indicates that A913 grades 50 and 65 are weldable without preheating when the product temperature is above 32°F 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 steel grades, highly restrained conditions and large material thickness may require some preheating . In most cases highly restrained conditions can be avoided by choosing adequate weld sequencing . Selection of strength level of consumables is shown in AWS D1 .1 Table 2 .3 . Prequalified combinations of base metal and filler metal for matching strength are listed in AWS D1 .1 Table 3 .1 .

Can A913 be used in combination with other grades?Yes . When welding A913 to A992 or A36, preheating is typically needed for the 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 a Silicon content ranging between 0 .15 and 0 .25 percent, and as such is suitable to be galvanized .

What about flame cutting shapes in A913?A913 can be cut with a torch using the same procedures applied to any structural steel . Due to the low carbon equivalent of A913, preheating in order to prevent cracking is generally not necessary for product temperatures above 32°F .

What about flame straightening shapes in A913?As with any structural steel it is possible to eliminate deformations or to give a member a special shape by flame straightening . For local reheating of the entire material thickness the maximum flame straightening temperature is 1200°F . For local superficial reheating of the surface only, the maximum flame straightening temperature is 1650°F .

What about machining shapes in A913?A913 can be machined under the same conditions as grades with the same level of yield strength . Drilling and cutting tests on A913 showed no difference in tool wear than for other structural grades of the same strength level . In fact using higher strength steel allows the designer to reduce the size (thickness) of the material and thus to reduce the machining time .

What about stress relieving of shapes in A913?Stress relieving post weld heat treatment (PWHT) may be necessary when the layout of the structure and/or the expected stress condition after welding requires a reduction of the residual stresses . If stress relieving is required, it should be performed in the same manner as for any structural steel grade . The temperature should range between 980°F and 1080°F . The holding time should be two minutes per mm (1/25") of material thickness, but not less than 30 minutes and not more than 90 minutes .

Which sections can be delivered according to A6 S30 (Supplement 2)?The following profiles are available with Charpy values per 20 ft-lbf at 70°F in the alternate core location (S30 per ASTM A6):

W14 x 211 – 873 W24 x 229 – 370 W36 x 282 – 925 W40 x 235 – 392 W40 x 277 – 655 W44 x 290 – 335
