There are some fatigue damage estimation methods of the austenitic stainless steel (SUS304 and S316) that uses the change of electromagnetic properties by fatigue. For instance, they are the remanent magnetization method, the excitation method, and so on. It is well known that the relation between fatigue damage and the remanent magnetization of them is simple, clear, and reproducible. On the other hand, the excitation method such as the inductance method using a pancake type coil can use easily on the site. In this paper, two fatigue evaluation methods such as the remanent magnetization method and the excitation method are introduced. In addition, we report on the result of comparing the fatigue evaluation performances of two methods.
