摘　　要：研究了耐海水腐蚀新型双相不锈钢ＮＨＳ—１的组织及其耐蚀性能。通过金相显微镜和Ｘ射线衍射观察和分析了这种钢的金相组织。多种腐蚀试验结果表明，新型双相不锈钢在海水介质中具有良好的耐均匀腐蚀性能及抗晶间腐蚀性能，且其抗点蚀性能优于Ｃ１５钢。The microstructure and corrosion-resistance of a new double stainless steel for pumps used in seawater were studied. The metallurgical structure of the steel was observed and analyzed by means of metallurgical microscope and X-ray diffraction.The result of manifold corrosion tests shows that the steel possesses good uniform corrosion resistance in seawater and good intergranular corrosion resistance, and its pitting corrosion resistance is higher than that of C15 steel.
