It includes rounds, squares, and hexagons, and hot-rolled or extruded shapes, such as angles, tees, and channels in the more commonly used types of stainless steels. The bars shall be furnished in one of the following conditions: Condition A in which the bars are annealed, Condition H in which the bars are hardened and tempered at a relative temperature, Condition T in which the bars are hardened and tempered at a relatively high temperature, Condition S in which the bars are strain hardened or relatively light cold worked, and Condition B in which the bars are relatively severe cold worked. The material shall be subjected to a mechanical test to determine its tensile strength, yield strength, elongation, and Brinell hardness.
SCOPE
1.1 This specification covers hot-finished or cold-finished bars except bars for reforging (Note 1). It includes rounds, squares, and hexagons, and hot-rolled or extruded shapes, such as angles, tees, and channels in the more commonly used types of stainless steels. The free-machining types (Note 2) for general corrosion resistance and high-temperature service are covered in a separate specification.  
Note 1: For bars for reforging, see Specification A314.
Note 2: For free-machining stainless bars designed especially for optimum machinability, see Specification A582/A582M.
Note 3: There are standards covering high nickel, chromium, austenitic corrosion, and heat-resisting alloy materials. These standards are under the jurisdiction of ASTM Subcommittee B02.07 and may be found in  Annual Book of ASTM Standards, Vol. 02.04.  
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. The inch-pound units shall apply unless the “M” designation of this specification is specified in the order.  
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Specification for Carbon and High-Strength Electric Resistance Forge-Welded Steel Structural Shapes

ABSTRACT
This specification covers carbon and high-strength steel shapes of structural quality manufactured by the electric resistance forge-welding process from coils. The specimens shall be established by the steel supplier, shape manufacturer, and shape purchaser of the materials. Specimens shall conform to the required chemical compositions of carbon, manganese, phosphorus, sulfur and silicon. Specimens shall undergo tension tests, peel tests and tee tension tests and shall conform to the required values of tensile strength, yield point, and elongation.
SCOPE
1.1 This specification covers carbon and high-strength steel shapes of structural quality manufactured by the electric-resistance forge-welding process from coils.  
1.2 The size range covered is described in nominal dimensions for columns, beams, and tees.    
Size Range, in. (mm)  
Web thickness  
0.060 to 0.500 [1.5 to 12.7]  
Flange thickness  
0.060 to 0.500 [1.5 to 12.7]  
Overall depth  
2.00 to 24.00 [50 to 600]  
Flange width  
0.50 to 12.00 [12.7 to 300]  
1.3 These shapes are intended for two classes of application:  
1.3.1 Class 1—General structural use where static loading predominates.  
1.3.2 Class 2—Structural use where fatigue loading occurs and is a principal design consideration.  
Note 1: Caution—Because of the absence of smooth, integral, large radius fillets at the junctions of the webs and the flanges (see Fig. 1), fatigue limits of resistance forge-welded shapes in torsion, lateral loading, and flexure are usually lower than those for hot-rolled shapes of similar size and material. Users should consult shape manufacturers for recommended values of fatigue limits for each specific use, material, and size in cases where dynamic loading is a principal design consideration.  
FIG. 1 Appearance of Peel Test Criteria  
1.4 When the steel is to be welded, it is presupposed that a welding procedure suitable for the grade of steel and intended use or service will be utilized. See Appendix X3 of Specification A6/A6M for information on weldability.  
1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
1.6 The following safety hazards caveat pertains only to the test methods portion, Section 10, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ABSTRACT
This specification covers bars and shapes of age-hardening stainless steels. Hot-finished or cold-finished rounds, squares, hexagons, bar shapes, angles, tees, and channels are included. These shapes may be produced by hot rolling, extruding, or forging. Type 631 and 632 stainless steels contain a large amount of ferrite in the microstructure and can have low ductility in forgings and large diameter bars. Material of types other than XM-16, XM-25, and Type 630 shall be furnished in the solution-annealed condition, or in the equalized and oven-tempered condition. Types 630, XM-16, and XM-25 may be furnished in the solution-annealed or age-hardened condition. Type UNS S46910 shall be furnished in solution annealed, cold-worked or aged-hardened condition. Shapes may be subjected to either Class A or Class C preparation for removal of visible surface imperfections. The material shall be subjected to tension, impact, and hardness tests.
SCOPE
1.1 This specification2 covers bars and shapes of age-hardening stainless steels. Hot-finished or cold-finished rounds, squares, hexagons, bar shapes, angles, tees, and channels are included; these shapes may be produced by hot rolling, extruding, or forging. Billets or bars for reforging may be purchased to this specification.  
1.2 These steels are generally used for parts requiring corrosion resistance and high strength at room temperature, or at temperatures up to 600 °F [315 °C]; 700 °F [370 °C] for Type 632; 840 °F [450 °C] for Type UNS S46910. They are suitable for machining in the solution-annealed condition after which they may be age-hardened to the mechanical properties specified in Section 7 without danger of cracking or distortion. Type XM-25 is machinable in the as-received fully heat treated condition. Type UNS S46910 is suitable for machining in the solution-annealed, cold-worked, and aged-hardened condition.  
1.3 Types 631 and 632 contain a large amount of ferrite in the microstructure and can have low ductility in forgings and larger diameter bars. Applications should be limited to small diameter bar.  
1.4 The values stated in either inch-pound units or SI (metric) units are to be regarded separately as standards; within the text and tables, the SI units are shown in [brackets]. The values stated in each system are not exact equivalents; therefore, each system must be used independent of the other. Combining values from the two systems may result in nonconformance with the specification.  
1.5 Unless the order specifies an “M” designation, the material shall be furnished to inch-pound units.  
Note 1: For forgings, see Specification A705/A705M.
Note 2: For billets and bars for forging see Specification A314.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
