The SCC behavior of austenitic stainless steels (type 304 and type 316) was investigated in acidic chloride and sulfate solutions using constant load, constant strain and slow strain testing methods. Particular attention has been paid here to whether these testing methods contain parameters which allow accurate prediction of the time to failure. It was found that the parameters were steady state elongation rate for constant load, stress relaxation rate for constant strain, and maximum stress ratio for slow strain rate testing, respectively. The comparison between the characteristics of these parameters led to the conclusion that the best parameter for the prediction of time to failure was the steady state elongation rate, by which time to failure could be predicted at an early period of SCC experiment.
