Effect of Chloride Concentration on Stress Corrosion Cracking Susceptibility of Stainless Steel in Black Water

The sensitivity to stress corrosion cracking (SCC) of 00Cr18Ni10 stainless steel in black water with different Cl^- concentrations was studied by slow strain rate test. The results show that the sensitivity to stress corrosion cracking of 00Cr18Ni10 stainless steel increased with the increase of Cl^- concentration, and the critical Cl^- concentration for SCC to occurr was 16.8 mg/L.
