C1045 ASTM 1020 Aisi 1010 Steel Hot Rolled Bar Stock Polishing Round
ASTM 1020 Carbon Steel Hot Rolling / Polishing Round Bar
The strength is slightly higher than that of 1015 steel, with little quenching and no temper brittleness. Cold deformation has high plasticity and is generally used for bending, calendering, bending and hammer arch processing. The welding performance of electric arc welding and contact welding is good. The thickness of gas welding is small, and cracks are easy to occur on the parts with strict shape requirements or complex shape. The machinability of cold drawing or normalizing state is better than that of annealing state, which is generally used for manufacturing with low stress and high toughness requirements.,
