Standard Specification for High-Strength Low-Alloy Structural Steel with 50 ksi [345 MPa] Minimum Yield Point to 4 in. (100 mm) Thick
|Publication Date:||30 July 1982|
|ICS Code (Heat-treatable steels):||77.140.10|
This specification covers high-strength low-alloy structural steel shapes, plates, and bars for welded, riveted, or bolted construction but intended primarily for use in welded bridges and buildings where savings in weight or added durability are important. The atmospheric corrosion resistance of this steel is approximately two times that of carbon structural steel with copper (Note). Welding technique is of fundamental importance, and it is presupposed that welding procedure will be suitable for the steel and the intended service. This specification is limited to material up to 8 in. (200 mm) inclusive in thickness.
NOTE-Two times carbon structural steel with copper is equivalent to four times carbon structural steel without copper (Cu 0.02 max)
The values stated in inch-pound units are to be regarded as the standard.
