摘要
汽轮发电机护环由于应力腐蚀开裂而失效,在国内外并不少见、本文讨论了护环应力腐蚀的成因和防止腐蚀的措施,并介绍了耐腐蚀的18Mn-18Cr新钢种。
Retaining rings failures caused by stress corrosion cracking have not seldom occurred in our and other countries.In this paper, causes of retaining rings stress corrosion and precautions against stress corrosion are discussed and the advanced corrosion resistant 18Mn-18Cr steel is introduced.
