20Cr Alloy Structure Steel China Steel Grade Standard GB

Hardening of GB Alloy structural steel 20Cr; First quenching heated slowly to 880°C, Then after adequate soaking at this temperature quench in oil or water. Temper as soon as tools reach room temperature. Second quenching heat to 780-820°C then quenching in oil or water. Tempering of 20Cr Alloy structural steel 20CrMo Steel Equivalent, Chemical Composition, Mechanical 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..
