摘要 采用高温高压慢应变速率拉伸试验方法,考察304奥氏体不锈钢在含硼和锂离子的介质中的应力腐蚀敏感性。 结果显示,材料的处理方式、介质中含氧及氯离子等均影响该钢种的应力腐蚀破裂敏感性,试样表层氧化膜也发生相 应的变化。 Stress corrosion cracking (SCC) of 304 stainless steel in high temperature water containing H3BO3 and Li+ was studied using slow stain rate test (SSRT). The results showed that heat-treatment of the material, oxygen or /and chloride concentration in the water all affected the SCC susceptibility of this material. The surface oxide films changed relatively.
