Based on statistical natures of the crack initiation life t_i and the crack propagation life t_p, a method for predicting dependence of the distribution of the total life t_f(=t_i + t_p) on various factors was proposed. Applying the method to stress corrosion cracking(SCC) of a Ni-Cr-Mo steel in 3.5% NaCl solution, notch acuity and temperature dependence of the distribution of t_f were predicted. In order to examine the prediction, statistical SCC tests were conducted. The prediction was in good agreement with the experimental result. Furthermore, the loading type and the stress level dependence of the distribution of t_f were discussed. The experiments also reconfirmed the statistical features of t_i, t_p and t_f as found in the previous study.
