In the previous report, it was found that low-cycle fatigue strengths were accurately estimated by a multivariate analysis on basic material factors such as chemical composition and heat treatment temperature under limited conditions which were classified by the materials used, the heat treatment conditions being the same as those in the case of high-cycle fatigue properties. In this report, a procedure for the prediction of S-N curves was examined using the same analytical procedure developed previously. It was concluded that the procedure developed in this report is quite suitable for the prediction of S-N curves.
