Experimental Study on Chloride Stress Corrosion Cracking Sensitivity of 316L Stainless Steel

The slow–strain-rate tensile test was used to study the chloride stress corrosion cracking (SSC) behavior of 316L stainless steel under simulated condition a CO2 gas field in Tarim Basin, and effects CO2, Cl? concentration, temperature on sensitivity SCC were discussed. results show that increase content has no apparent influence steel. With rise temperature, SCC’s increases, change index Iscc is noticeable. When concentration also increases. degree three factors experimental can be ranked as follows: temperature>Cl? > CO2. In this experiment, when partial pressure 0.1 MPa, 65°C, 1,20,000 mg/L, samples maximum 26.8%.
