Abstract

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 tempera-ture was developed using an environmental parameter β that depends upon temperature, molybdenum concentration, and yield strength of the SS.
