对ZGCr15钢进行热处理工艺试验 ,分析了工艺参数对残余奥氏体量的影响 ,优选了热处理工艺 ,使ZGCr15钢残余奥氏体量控制在 5%以内 ,保证了热处理质量及尺寸稳定性
The heat treatment process of ZGCr15 steel was studied. The influence of technological parameters on the retained austenite content was analyzed. The heat treatment process was optimized to keep the residual austenite content within 5% of ZGCr15 steel, which ensured the quality of heat treatment and the dimensional stability
