【摘要】 用慢应变速率实验技术研究了敏化态３０４不锈钢在室温氯化钠溶液中的应力腐蚀行为。结果表明：敏化态３０４不锈钢在近中性的氯化物溶液中呈典型的沿晶应力腐蚀开裂，随Ｃｌ－浓度的提高，应力腐蚀开裂敏感性增强，应力腐蚀的发生存在一个临界Ｃｌ－浓度。关键词更多还原

【Abstract】 The susceptibility to SCC of sensitized 304SS in chloride solutions at room temperature has been examined by SSRT method. The results showed that sensitized 304SS fractured intergranularly.The susceptibility to SCC is enhanced with the increase of Cl￣-concentration. There exsits a critical Cl￣-concentration for occuring SCC of the sensitized 304SS.更多还原
