ASTM1020 steel coil is a high-quality carbon structural steel, cold plastic deformation is high. ASTM1020 carbon structural steel coil is slightly higher than 15, very little quenching, no temper brittleness. Cold deformation crack-prone high plasticity, usually for bending, welding performance calender, curved edges and hammer arch and other processing, and the contact arc welding, gas welding small thickness, shape demanding or complex shape of the workpiece.ASTM 1020 steel coil,cutting of cold drawn annealed or normalized condition than the state is good, generally used to make large discontinuity toughness requirements.
