40Cr steel is one of the widely used steels in the machinery manufacturing industry. After quenching and tempering, 40Cr alloy steel has good comprehensive mechanical properties, good low-temperature impact toughness and low notch sensitivity.
40Cr steel properties
40Cr steel has good hardenability. It can be hardened to Ф28～60mm in water quenching and Ф15～40mm in oil quenching. In addition to quenching and tempering, this steel is also suitable for cyanidation and high-frequency quenching. The cutting performance is better. When the hardness is 174～229HB, the relative machinability is 60%. The steel is suitable for making medium-sized plastic molds.
Heat treatment of 40Cr steel:
Secondary quenching heating temperature (℃): 850; coolant: oil
The second quenching heating temperature (℃):-
