摘　　要：采用对比分析法对国产新研制的控氮00Cr17Ni12Mo2(ANSI316LN)与0Cr18Ni10Ti(ANSI321)不锈钢管材的化学成份、力学性能、耐腐蚀性能等进行研究。研究表明,316LN新型管材综合性能在反应堆一回路系统运行工况下优于321管材,完全可以实现对321管材的替代。The metallurgical,physical and mechanical performance,and the corrosion and welding properties Of 00Cr17Ni12Mo2 （controlled Nitrogen,ANSI316LN） and 0Cr18Ni10Ti （ANSI321SS） for main pipe material were analyzed comparatively in this paper.The feasibility of 316LN pipe material manufacturing was studied too.The analysis results showed that under the operation condition of the nuclear reactor,the general properties of 316LN are better than that of 321SS.Therefore,316LN could be used for main pipe material,replacing 321SS.
