摘要：

Stress corrosion cracking (SCC) susceptibility of heavy-thick low alloy steels was investigated by slow strain rate tensile (SSRT) tests in high temperature water containing various levels of dissolved oxygen (DO) at temperature of 373 K to 593 K. Rolled steels with high sulfur content had SCC susceptibility in the wide region of temperature-DO concentration combination, even in DO<0.005 ppm at 473 K. A forged steel with extremely low sulfur content was almost immune to SCC. SCC maps as functions of temperature and DO concentration were proposed for each steel from the SSRT tests results.
