| Abstract: | The paper introduced a set of heat treatment process on the structure and hardness of GGr15 steel after forging.The process is that first pre-heat treating including sorbide heat treatment process in air-cooling solution treatment on780℃for 0.5hafter cooling for 659℃,isothermal anneal in air-cooling solution treatment on 710℃for 2h.,and then eventually treating including quenching about oil-cooling（oil temperature is 30~60℃）solution on 840℃for 0.5haged condition.tempering in air-cooling solution treatment on 150 ℃ for 2h,at last,additional tempering is air-cooling solution treatment on 120℃for 3h.The hardness of stainless steels was markedly increased after heat treatment process.The hardness of the GGr15 bearing steel reached above 63 HRC,which met the requirements of usage. |
