1: 25CrMo4 steel introduction
25CrMo4 is an alloy structural steel. 25CrMo4 is special steel of German grade, which is equivalent to structural steel of 25CrMo grade in China. It has high hardenability, no temper brittleness, good weldability, little tendency to cold crack, good machinability and cold strain plasticity. It is generally used and tempering or carburizing and quenching state.
