Research on the Heat Treatment Technique for 35CrMo Steel to Get Lath Martensite Microstructure

The heat treatment technique for 35CrMo steel to get lath martensite microstrure and the contact fatigue of this lath martensite were researched.The results indicate that the contact fatigue life of this lath martensite is four times higher than the condition of quenched and tempered microstructure of this steel.
