Interim Guidelines Advisory No. 2 SAC 99-01 Metallurgy & Welding 8-5A709 Gr.50 vs A588 - American Welding SocietyThe A709 Gr 50 is equivalent to A572 Gr 50. The answer is yes you can, unless you are working with a contract requiring otherwise. I normally run D1.5 PQRs with A588/A709-50W so that the test will qualify the lesser grades as well. I would carefully review the A588 MTR to be sure that the material fully meets ALL requirements of A709, because sometimes the documentation has errors and omissions.ASTM A36 steelASTM A36 Carbon Structural Steel Plate ASTM A36 steel plate is the most widely used hot-rolled steel product. As a kind of carbon structural steel product, its relative products are round rod steel, angle bar, and steel sections such as I-Beams, H-beams, angles, and channels.
