When the steel is to be welded, a welding procedure suitable for the grade of steel and intended use or service is to be utilized. See Appendix X3 of Specification A6/A6M for information on weldability. The values stated in either inch pound units or SI units are to be regarded separately as standard.
Apr 17, 2009 · Although the original ASTM A992 00 was for W shapes only, the current A992 01 covers rolled steel, structural shapes for use in building framing, bridges, or for general structural purposes,". ASTM A992 01 was expanded in scope to cover rolled structural steel shapes such as M, S, HP, channels and angles.
The ASTM A992 standard specification is employed most frequently in building framing components such as I beams and wide flange shapes. In addition to building frames, A992 steel is frequently found in bridge construction and other public infrastructure. This steel is defined by a mixture of elements that includes copper,

Nov 01, 2007 · Can anyone tell me why the switch was made from A572 steel to A992 steel for typical structural steel? I know that A572 is still available, but A992 is what we spec and I believe the most prevalent. does it have anything to do with ductility problems associated with the Northridge earthquake in California in 1994?

Nov 01, 2007 · A992 steel guarantees a maximum ratio of Fy to Fu of 0.85, to ensure that the material is ductile. With A572, Fy could theoretically go all the way up to Fu, which wouldn't give you any elongation between yield and fracture.
