摘　　要：铁素体不锈钢的应用越来越多,但不锈钢晶间腐蚀试验还缺乏国家标准。介绍了铁素体不锈钢晶间腐蚀的机理,讨论了针对铁素体不锈钢的ASTMA763-93晶间腐蚀试验方法,并对ASTMA763-93未涵盖的低铬铁素体不锈钢的晶间腐蚀试验方法进行了补充。Ferritic stainless steels are finding more and more applications in engineering.Unfortunately, national standard test methods have been established for detecting susceptibility of ferritic stainless steels to intergranular corrosion.Thus the mechanism of interg-ranular corrosion of ferritic stainless steels was introduced, and the ASTM-A763 standard for testing intergranular corrosion of ferritic stainless steels was discussed.Moreover, the method for testing intergranular corrosion of low chromium ferritic stainless steels, not covered in ASTM-A763 standard, was discussed as a modification.
