浓度和温度对316L不锈钢在NaOH溶液中应力腐蚀开裂行为的影响

Stress Corrosion Cracking of 316L Stainless Steel in NaOH Solution at High Temperatures

采用慢应变速率拉伸试验(简称SSRT),对316L不锈钢在高温NaOH溶液中的应力腐蚀开裂行为进行了试验研究,结果表明在较高温度下,316L不锈钢在低浓度的NaOH溶液中也具有明显的应力腐蚀开裂敏感性。

The SCC behavior of 316L austenitic stainless steel was investigated by using slow strain rate tests （SSRT） in NaOH solutions at high temperatures. The results showed that at high temperatures, even in low NaOH concentration solution, the SCC susceptibility of 316L was apparent.
