ASTM A514 steel plates are conventional quenched and tempered Alloy steel plates, which are designed for structural applications. Under ASTM A514/ A514M Technical standard, there are a variety of chemistries: grade A, B, C, E, F, H, J, K, M, P, Q, S, and T. Each of the grade has different chemistry requirements, but all of them have the same mechanical properties.
ASTM A514 Grade E quenched and tempered alloy steel plates are widely used to make crane booms, heavy vehicle frames and chassis, transport trailers, mobile man-lifts, construction equipment, agricultural equipment, and welded bridge structural members., etc.
According to ASTM A514/ A514M Technical standard, the max thickness of ASTM A514 Grade E quenched and tempered alloy steel plate is 150mm. ASTM A514 Grade E steel material shall be heat treatment by the ASTM A514 steel mill to conform to the tensile and hardness requirements by heating to not less tnan 900 degree and quenching in water or oil, tempering at not less than 620 degree.
