ASTM A572-20 steel plates sizes 3/16” – 4”

ASTM A572-20 steel plates Post-weld heat treatment may degrade head-affected zone strength and toughness. Pretesting of specific welding and post-weld heat treating procedures is recommended to assure optimization of final property levels. ASTM A572-20 steel plates have a higher yield and tensile strength than A36 plate, combined with a lower weight.

ASTM A572-20 steel plates are ductile and easy to form. ASTM A572-20 steel plates can be successfully machined with the appropriate techniques and is easy to weld. ASTM A572-20 steel plates are a high strength low alloy (HSLA) columbium-vanadium steel and is available in grades 42, 55, 60 and 65. ASTM A572, a high strength, low alloy steel plate that offers an optimum combination of strength, weldability and notch toughness with economy.
