316L钢在含H2S、Cl-水溶液中的慢应变速率腐蚀试验研究

摘要

通过慢应变速率法(SSRT)应力腐蚀试验，得到了316L钢的应力腐蚀敏感性指数，回归出计算应力腐蚀敏感性指数的方程，表明水溶液中Cl-对316L钢的应力腐蚀影响较大，而H2S的影响小。%Through the stress corrosion test of slow strain rate test, the sensitive indexes of the stress corrosion of 316L stainless steel was derived, the regression equation was given for calculating the sensitive indexes of stress corrosion of 316L stainless steel. It shows that the influence of Cl- in solution on the stress corrosion of 316L stsinless steel was some strong and the influence of H2S in solution on the stress corrosion of 316L stainless steel was rnsmall.
