Alloy steels are designated by AISI four-digit numbers. They comprise different kinds of steels which exceed the composition limits of Mn, C, Mo, Si, Ni, Va, and B set for carbon steels. They respond more quickly to mechanical and heat treatments than carbon steels.
ASTM A514 Alloy & Abrasion Resistant Steel Plate Chapel ASTM A514. A quenched & tempered, high-strength, weldable steel plate utilized in structural applications. Because of this materials high yield strength it is ideal for projects requiring a light
ASTM A514 steel plate/sheet is a quenched and tempered high yield strength steel used in structural applications where high strength and low weight are critical.The tensile yield strength of A514 is specified as at least 100ksi(689MPa) for thicknesses up to 2.5 inched(63.5mm) thick plate,and at least 110ksi(758MPa) ultimated tensile strength,with a specified ultimate range of 110-130 ksi (758-896 MPa).Plates from 2.5 to 6.0 inches (63.5 to
