Description
GB 20CrMo steel is a kind of Chinese alloy steel for engineering and mechanical structure purpose, which is generally used in quenching or tempering or carburizing and quenching. 20CrMo material has high heat strength, good hardenability, no temper brittleness, cold strain plasticity, good machinability and weldability. 20CrMo alloy steel is used in the manufacture of non-corrosive media in chemical equipment and high pressure pipes, fasteners, steam turbines, boiler blades and forgings with working temperature below 250 °C, and important carburizing parts such as gears and shafts in general machines. It can also be used in place of 1Cr13 steel to manufacture medium pressure, low pressure steam turbines in the superheated steam zone pressure stage working blades. 20CrMo material equivalent to US ASTM, European Germany DIN EN, British BS EN, France NF EN, Japanese JIS, and ISO standard.
