Slow strain rate tests and constant strain corrosion tests were employed to study the effect of pre-strain on stress corrosion cracking behavior and initiation mechanism of E690 steel in simulated marine atmosphere. Results revealed that pre-strain can result in enhancement of both anodic and cathodic reactions of E690 steel in simulated marine atmosphere. Intergranular corrosion and microcracks formed after 4 days of exposure in sulfite-containing marine atmosphere at constant pre-strain, which consequently caused detrimental effects on the mechanical properties and subsequent SCC behavior of E690 steel. The presence of sulfite and high-angle grain boundaries of prior austenite grain boundaries (PAGBs) accounted for the intergranular corrosion and SCC initiation along PAGBs.
