ASTM A992/ASTM A572-GR 50 is a High Strength Low Alloy Steel that is used in general structural applications when the structural will be riveted, bolted, or welded. ASTM A572-GR50 is Columbium-Vanadium Steel that offers a minimum yield of 50 KSI and is used whenever a cost savings from a weight reduction can be gained.
ASTM A588 is a High Strength Low Alloy Steel that is used in general structural applications when the structural will be riveted, bolted, or welded. ASTM A588 is a Copper bearing steel that offers a minimum yield of 50 KSI and has approximately two to four times the corrosion resistance of carbon steel without copper. ASTM A588 structurals are used whenever a cost savings from a weight reduction can be gained or when there are concerns about atmospheric corrosion.
ASTM A36 is a Carbon Steel that is used in general structural applications when the structural will be riveted, bolted, or welded. ASTM A36 is produced to mechanical properties offering a minimum yield of 36 KSI and a minimum tensile of 58 KSI. A36 is available as a special order from the mill.
