Experimental data from published literature on stress corrosion cracking (SCC) of austenitic stainless steels (SS) as influenced by temperature and stress in concentrated chloride solutions were analyzed using the chemical-mechanical correlation model. Effects of stress and temperature on SCC were analyzed using 63 sets of data for times to failure (tf) from 17 references. The data followed a systematic pattern which was described by the chemical-mechanical correlation model. An equation of tf as a function of stress and temperature was developed using an environmental parameter β that depends upon temperature, molybdenum concentration, and yield strength of the SS.
