Differences between ASTM A573 Steel and ASTM A572 SteelASTM A573 standard specifies structural quality carobn steel plate in three tensile strength ranges (A573 Grade 58, A573 Grade 65,
A573 Grade 70).
ASTM A572 standard specifies five grades of high-strength low-alloy structural steel shapes, plates, sheet piling, and bars (,A572 Grade 42, A572 Grade 50, A572 Grade 55, A572 Grade 60, A572 Grade 65).
