In the research of fatigue of metals, fatigue properties of ultra low carbon steels are important as a fundamental reference data for structural carbon steels. Thus, fatigue test data for low carbon steel of S10C and pure iron in rotating bending were extracted from the “Database on Fatigue Strength of Metallic Materials” published by JSMS. Applying the JSMS standard (JSMS-SD-6-04) “Standard Evaluation Method of Fatigue Reliability for Metallic Materials –Standard Regression Method of S-N Curve–”, S-N curves were analyzed on the basis of the “semi-logarithmic bilinear model with fatigue limit” for the respective series of fatigue data. It was found that S-N property of the individual material was well normalized by tensile strength of σB. Based on this aspect, a number of fatigue data extracted were pooled altogether and P-S-N property was also analyzed by the above standard (JSMS-SD-6-04). Analytical results thus obtained are usefully applied as the fundamental data for the reliability design of the mechanical structures in the various areas.
