【ABSTRACT】The test research on heat treatment process and property of GCr15SiMo
high hardenability bearing steel has been made. The test result show s that the GCr15SiMo
steel not only has higher anti softenessproperty in tempering andw ider tempreture range in
hardening and tempering, but also has better dimension stability and longer contact fatigue
life than GCr15SiM n steel.
