Abstract

Abstract: Effect of different controlled forging and cooling processes on mechanical properties of GCr15 steel was investigated by means of testing the tempering stability, impact property and rolling contact fatigue life. The results show that the tempering stability of the specimens can be improved by using controlled forging and controlled cooling technology, the impact property can be increased by more than 50%, and the contact fatigue life can be increased by more than 40%.

Key words: GCr15 bearing steel, controlled forging and cooling process, tempering stability, impact property, rolling contact fatigue
