To prevent a serious accident by the metal degradation of a structure made of iron-based structural materials, we have already proposed some fatigue evaluation methods for various iron-based structural materials. One of these is a residual magnetization method that uses a thin-film flux-gate magnetic sensor. This method is called the perpendicular residual magnetization method. This fatigue evaluation method had a good correlation between the magnetic sensor output signal and the amount of plane bending fatigue damage in the iron-based structural materials. However, we have not yet evaluated the pulsating tension fatigue damage of iron-based structural material such as the austenitic stainless steels using this method. In this paper, we report the evaluation results of a pulsating tension fatigue damage accumulation in austenitic stainless steels (SUS316 and SUS316L) using the perpendicular residual magnetization method. From our experiment, the maximum value of the Z component residual leakage magnetic flux density clearly depends on the magnitude of pulsating tension and the number of stress cycles.
