前言 传统的18-8型不锈钢,在海水及具有卤素族离子的介质中,很容易产生严重的局部腐蚀(点蚀和缝隙腐蚀)。随着海洋事业的发展,60年代以来,国内外冶金工作者均在积极探索,研制具有优良耐局部腐蚀的新型不锈钢。 本所在七O五所、北京钢铁学院、上钢五厂、上钢三厂共同协作下于70年代中期研制成功的00Cr20Ni25Mo5,是一种超低C、高Mo、Cr-Ni全奥氏体不锈钢。这种新型不锈钢不仅可以应用于海洋工程,而且还可
Preface Traditional 18-8 stainless steel is prone to severe localized corrosion (pitting and crevice corrosion) in seawater and halogenated ion-bearing media. With the development of marine undertakings, since the 1960s, metallurgical workers at home and abroad are actively exploring and developing new types of stainless steel with excellent resistance to localized corrosion. The 00Cr20Ni25Mo5 developed by our institute in 1970, Beijing Institute of Iron and Steel, Wuchang 5, Shangsan 3 works in the mid-1970s is a kind of ultra-low C, high Mo, Cr-Ni all austenitic stainless steel. This new type of stainless steel can be applied not only to offshore engineering, but also
