Product Description

20#/1020/S20C Cold Drawn Round Steel for Car headrest rod steel




The steel belongs to high quality low carbon carbon steel, cold extruded, carburized and hardened steel. The steel has low strength, good toughness, plasticity and weldability. The tensile strength is 253-500MPa, and the elongation is ≥24%.

Uses: suitable for the manufacture of small and medium carburizing and carbonitriding parts that are not important for the construction of automobiles, tractors and general machinery manufacturing, such as handbrake shoes, lever shafts, gearbox speed forks, transmission passive gears and Tractor camshafts, suspension equalizer shafts, equalizer inner and outer bushings, etc.; used to manufacture various mechanical parts that are not stressed but require high toughness under hot-rolled or normalized conditions; in heavy and medium-sized machinery manufacturing In, such as forged or pressed tie rods, shackles, levers, sleeves, clamps, etc. In the steam turbine and boiler manufacturing industry, it is mostly used for pipes, flanges, headers and various fasteners working in non-corrosive media with a pressure of ≤6N/square and a temperature of ≤450ºC; used to make crosses on railways, locomotives and vehicles Castings such as heads and pistons.
