ASTM A572 Steel Plate
ASTM A572 Steel General Information
The ASTM A572 carbon steel specification covers the standard requirements for Grades 42, 50, 55, 60, and 65 for high-strength low-alloy columbium-vanadium structural steel shapes, plates and bars for applications in bolted, riveted and welded structures in bridges and buildings. Consequently, the combined use of columbium, vanadium, titanium meet the requirements of the producers and A572 specifications.
A572 most common grade is Gr. 42. PGI also carries A572 Gr. 50. A more difficult to find Gr. 65 steel plate is also available.
Dual Certification – A709 Grade 50
A572 Grade 50 is dual certified to A709 Grade 50. Carbon Steels A709-50 material is stocked primarily in Flat Rolled Products, but is also available to a lesser extent in Structural and Bar Products. A709-50 ASTM A709 is fracture critical and covers the requirements for structural steel for bridges and other structures. ASTM A572 Grade 50 steel requires a minimum yield strength of 50 ksi.
