20CrMo Alloy Steel. 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.. Applications20Mn2,GB T 3077-1999 20Mn2 steel,20Mn2 stainless steel gb t 3077 42simn quenching and tempering steel20Mn2 steel has medium strength. The coldstraining plasticity of 20Mn2 steel is high, low temperature property is good, weldability and machinability are passable. And compared with carbon steel with corresponding carbon content, the quench-hardening ability of 20Mn2 steel is higher. In oil the critical full hardening diameters are 4-15mm.
