SM570 steel is a low carbon, high strength structural steel With this low carbon equivalent, it process good cold forming property. SM570 steel plates usual supplied in normalized or control rolled delivery condition.
SM570 steel grade usual be used in machinery parts, boom, crane, chassis , buildings bridges and mobile equipment.The equal steel grade is ST52-3, A572 Gr.50, EN S355JR and so on.
