一种Cronidur30高氮不锈钢轴承零件热处理方法
摘要：
一种Cronidur30高氮不锈钢轴承零件热处理方法，属于轴承零件的加工领域，本发明为解决现有技术中无法对Cronidur30高氮不锈钢轴承零件进行热处理，从而导致材料为Cronidur30高氮不锈钢的轴承零件的耐腐蚀性低的问题，本热处理方法主要操作为首先选择热处理设备，其次对Cronidur30高氮不锈钢的零件进行两次预热处理，一次终热处理，再次将经过热处理后的零件进行气淬冷却，最后将冷却后的零件进行回火处理。本发明主要用于Cronidur30高氮不锈钢轴承零件的热处理加工。
摘要（英）：

The invention discloses a cronidur30 high-nitrogen stainless steel bearing part heat treatment method and belongs to the field of machining of bearing parts. The method is used for solving the problemthat in the prior art, heat treatment fails to be performed on the cronidur30 high-nitrogen stainless steel bearing parts, and consequentially, the corrosion resistance of the bearing parts made of cronidur30 high-nitrogen stainless steel is low. The heat treatment method mainly comprises the operation steps that firstly, heat treatment equipment is selected; secondly, the parts made of the cronidur30 high-nitrogen stainless steel are subjected to preheating treatment twice and final heat treatment once; thirdly, gas quenching and cooling are performed on the parts subjected to heat treatment; and fourthly and finally, tempering treatment is performed on the cooled parts. The cronidur30 high-nitrogen stainless steel bearing part heat treatment method is mainly used for heat treatment machining of the cronidur30 high-nitrogen stainless steel bearing parts.
