A514 is a special type of quenched and tempered high-strength alloy steel with a yield strength of 100,000 psi (100 ksi or approximately 700 MPa).A514 material is known for its high yield strength, weldability, and toughness, even at low temperatures. A514 plate is a low carbon quenched and tempered alloy steel that is a low-cost, high performing material for structural use and high wear machine applications.
ASTM A514 Steel Plate is used in heavy load machines and cranes and are available in heavy plate thickness.A514 steel is available in grade B, S, H, Q, E, F, A, and P.
