A572 Grade 50/60/65 I beam
A572 Grade50 steel plate is a low-alloy high-strength steel plate. A small amount of alloy elements are added to the steel plate. Through a special heat treatment process, the strength and toughness can be partially improved. Its yield strength ReL ≥ 345MPa, tensile strength Rm ≥ 450MPa, elongation A200 ≥ 18%, A50 ≥ 21%, can withstand greater pressure and tension, and is not easy to deform and break.
