AISI 1020 Steel is a mild carbon steel, 1020 steel belong to the 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.

ASTM 1020 mild steel is suitable for making cars, tractors and general machinery small and medium-sized carburizing and carbonitriding and other parts,fork lever shaft, transmission speed, transmission driven gear and the tractor on the camshaft, hanging equalizer axle, equalizer, inner and outer bushing, etc.; In the condition of hot rolling or normalizing used in the manufacture of force is not big, but all kinds of high toughness requirement of mechanical parts;

In medium and heavy machinery industry, such as forging or suppression of rod, shackle, leverage, sleeve, fixture, etc. In steam turbine and boiler manufacturing for more pressure or less 6N/㎡, the temperature of 450 ℃ or less corrupt media work of pipes, flanges, header, and various kinds of fasteners; On the railway and locomotive vehicles used in the manufacture of the crosshead and piston castings.
