摘　　要：奥氏体不锈钢在连多硫酸中会发生沿晶应力腐蚀开裂。连多硫酸浓度、氯离子的存在、不锈钢的热处理状态与组织对开裂有很大影响。可从环境、材料、应力3个方面来进行防护。In polythionic acid,the intergranular stress corrosion crack of stainless steel is occured.the SCC is conected with the density of the polythionic acid,the presence of chloridion,the heat treatment and the metallographical of the stainless steel.The protection can be taken from environment,material and stress.

关 键 词：奥氏体不锈钢 连多硫酸 应力腐蚀
