High strength ASTM A514 grades steel plates

High strength ASTM A514 grades steel plates are conventional quenched and tempered steel.
ASTM A514 grades are signed for structural applications. ASTM A514 grades are available in a variety of chemistries: A, B, C, E, F, H, J, K, M, P, Q, S, and T. ASTM A514 grades steel plates are used where a weldable, machinable, very high strength steel is required to save weight or meet ultimate strength requirements.
