ASTM A514 steel plate - high yield strength, quenched and tempered alloy steel plate

ASTM A514 steel plate is conventional quenched and tempered steel. ASTM A514 steel plate is known for its high yield strength, weldability, and toughness, even at low temperatures. ASTM A514 steel is a particular type of high strength steel that is primarily used as a structural steel for building construction. ASTM A514 steel is available in a variety of chemistries: A, B, C, E, F, H, J, K, M, P, Q, S, and T. All of these A514 grades have the same mechanical properties.
