1020 steel round bar
1020 steel round bar is widely used in medium and heavy machinery industry, such as forging or suppression of rod, shackle, leverage, sleeve, fixture, etc. 1020 belongs to high quality low carbon steel, cold extrusion, carburizing and hardening steel. The low steel strength, toughness, plasticity and weldability are good. Tensile strength of 253-500 mpa, the elongation is 24% or higher.
