摘要
介绍了马氏体铬不锈钢、马氏体铬镍不锈钢和马氏体时效不锈钢的进展和发展动态,讨论了化学成分、热加工、热处理工艺对马氏体不锈钢组织和耐蚀性的影响。当前国内开发的新型马氏体不锈钢主要为符合给定服役条件的专用钢类。优化化学成分,提高钢的纯净度,通过热加工和热处理工艺控制钢的组织,进行表面处理是提高马氏体不锈钢耐蚀性的有效途径。
Progress and development status of chromium martensitic stainless steel, chromium-nickel martensitic steel and maraging （martensitic aging） steel are presented. The effect of chemical compositions, hot work and heat treatment process on structure and corrosion resistance of martensitic stainless steels is discussed. Domestic main new developed martensitic stainless steels are special steel grades to meet given service condition. Optimizing chemical composition, increasing cleanliness of steel, using hot work and heat treatment process to control structure and carrying out surface treatment are effective way to increase the corrosion resistance of martensitic stainless steels.
