中文摘要：60Si2MnA钢片状弹簧热处理时表层脱碳导致表层与心部组织及性能差异，造成弹簧复位偏差超标。采用渗碳淬火或高频感应加热淬火，可以有效防止表层脱碳，改善表层与心部组织差异及应力状态，使弹簧复位偏差控制在标准范围内。
英文摘要：After the heat treatment, surface decarburization of 60Si2MnA steel lesf spring lead to metallographic structure and mechanical properties differences between the surface and the center , and cause spring return deviation beyond the standard deviation. The carburizing quenching or high frequency induction heating quenching can effectively prevent the decarburization, improve metallographic organization differences between surface and center, and improve the stress state, so as to make spring return deviation control in the standard range.
