ASTM A514 grades are Quenched and Tempered Alloy Steel with high strength for structural use. Among ASTM A514 grades, the A514 grade B, A514 grade S and A514 grade E are the most commonly used. ASTM A514 grades have a minimum yield strength of 100 ksi (690 MPa). All ASTM A514 grades have the similar mechanical properties, but vary in chemical components and thickness.
ASTM A514 grades are limited to a range of thicknesses. And they are heat treated and have excellent weldability. Meanwhile, A514 plates provide good formidability and toughness. ASTM A514 grades are intended primarily for use in welded bridges and other structures. ASTM A514 grades are designed for use in cranes, trailers, mining and hauling equipment, etc.
