ASTM A572M “Standard Specification for High-Strength Low-Alloy Columbium-Vanadium Structural Steel” covers five grades of high-strength low-alloy structural steel shapes, plates, sheet piling, and bars.
ASTM A572 Grades 60 [415] is intended for riveted or bolted construction of bridges, or for riveted, bolted, or welded construction in other applications. Katalor always keeps thousands of high-strength low-alloy plates including SA572 Grade 60 plates.

Fo maximum sizes of A572 Gr.60 is same as Gr. 65. And the max sizes of plates and bars is 1-1/4in(32mm), while the max sizes of structural shape flanges or leg thickness is 2in(50mm).
Commonly the elongation of steel A572Gr.60 is min 16% (in 8 inches or 200mm) and 18% (in 2 inches or 50mm), But for plates A572Gr.60 wider than 24 in. [600 mm], the elongation requirement is reduced 3% points. See elongation requirement adjustments in the Tension Tests section of Specification A6/A6M.
In addition, the yield point levels of SA572 Grades 60 most closely approximating a geometric progression pattern between 36ksi [250 MPa], min, yield point steels covered by Specification ASTM A36/A36M and 100 ksi [690 MPa], min, yield strength steels covered by Specification ASTM A514/A514M.
