热处理对马氏体不锈钢KT5312AS6机械性能的影响

摘要

In this paper, the effect of heat treatment on structure and mechanical property of martensitic stain⁃less steel KT5312AS6 was tested. The result showed that the optimized heat treatment process for KT5312AS6 was as follows:oil cooling at 1 010℃~1 015℃for 60 minutes and air cooling at 565℃~570℃.%　　通过热处理对马氏体不锈钢KT5312AS6的组织和机械性能影响的试验，结果得出KT5312AS6钢最佳热处理制度为：1010℃～1015℃×60 min油冷+565℃～570℃空冷。
