摘　　要：采用慢应变速率拉伸法，研究了18Mn18Cr和18Mn5Cr两种护环钢在90℃的去离子水、22％NaCl和饱和NaNO3水溶液中的应力腐蚀开裂（SCC）行为。文中对两种护环钢的SCC抗力进行了讨论。The stress corrosion cracking (SCC) behavior of 18Mn18Cr and 18Mn5Cr steels for retaining ring was studied in aerated water, 22%NaCl and saturated NaNO3 solutions at 90℃ by the slow strain rate test.In this paper,the resistance to SCC of both retaining ring steels is discussed

关 键 词：护环钢 应力腐蚀开裂 慢应变速率 汽轮机
