| Abstract: |
| Objective To study the corrosion resistance of 316L and 2205 stainless steel in desalinated seawater and explore influences of water treatment agentia on corrosion resistance of stainless steel. Methods Electrochemical test, slow strain rate tensile test, SEM, etc. were adopted. Results The critical pitting temperature of 316L in desalinated seawater was 42.7 ℃. It was 70.2 ℃ after agentia was added; the critical pitting temperature of 2205 was higher than 85 ℃. The crevice corrosion resistance property of 2205 was better than 316L. The agentia also had corrosion inhibition effect on 2205. Both 316L and 2205 had high stress corrosion resistance in desalinated seawater at 50℃. Conclusion 316L is not suitable to be used in desalinated seawater directly, but is suitable to be used in desalinated seawater with agentia; 2205 is suitable to be used in desalinated seawater. |
