摘要
Abstract
Slow strain rate tests were adopted to study stress corrosion properties of 304 austenitie stainless steel in the environment of different concentration of acid NaCI solution at the temperature of 60℃. Test result showed that with the increasing of H<'+ concentration, stress corrosion cracking sensitivity increased, however, when H<'+ concentration reached a critical value, stress corrosion cracking sensitivity decreased drastically due to general corrosion. Although the mechanism of stress corrosion cracking for 304 stainless steel in acid NaCI solution is anodic solution, interaction of hydrogen and stress increased stress corrosion cracking sensitivity in the environment of acid NaCI solution.关键词
