【摘要】 研究了在硫酸介质中ＦＳ－１不锈钢的腐蚀性能和腐蚀电化学行为，分析讨论了该钢的热处理、组织结构和力学性能之间的关系．结果表明，以Ｃｒ３Ｎｉ２Ｓｉｘ（ｘ＝１～４）为主的硅化物在奥氏体中沉淀析出，强化、硬化基体，保证钢在浓硫酸中具有优良的耐腐蚀性能．可以代替国外进口的Ｌｅｗｍｅｔ镍基合金在硫酸工业中应用．更多还原

【Abstract】 FS 1 is one newly home made stainless steel, which shows performance strongly competitive with the know Lewmet nickle based alloy in sulphuric acid, and the FS 1 has widely been used in many factories as substitute to Lewmet alloy. It is showed that the main precipited phase of Cr₃Ni₂Si_x （x=1～4） strenthens and hardens the matrix. The corrosion performance and electrochemical behavior of FS 1 stainless steel in H₂SO₄ solution have been reported and the relationship among heat treatment, microstructure and mechanical properties of FS 1 ss have been discussed.更多还原
