摘　　要：根据对马氏体不锈钢耐蚀方面的要求，熔炼出了一种含钼马氏体不锈钢，对该不锈钢进行了淬火试验．研究了淬火温度对该马氏体不锈钢组织性能的影响，发现经1080℃淬火，钢的硬度达到最高，其原因是在该温度下淬火，钢中大部分碳化物溶解，且铁素体含量非常低，虽奥氏体晶粒有所长大，但幅度不大．因此，该马氏体不锈钢在1080℃左右进行淬火是比较合理的．A kind of martensitic stainless steel containing Mo element was smelted to improve the corrosion resistance properties. The microstructure and properties of the martensitic stainless steel quenching in oil were studied. It was found that the harness of the martensitic stainless steel reached the peak value when the quenching temperature was at 1080℃. This is due to the most of carbide was dissolved and a small quantity of ferrite existed. Austenite grain began to grow but too slowly at 1080℃. Therefore the reasonable quenching temperature for this kind of martensitic stainless steel is about 1080℃.
