The purpose of this study is to propose an effective procedure to predict the low cycle fatigue life of stainless steel products．By using the cantilever type rotational bending fatigue tester, the low cycle fatigue behavior of stainless steel was evaluated. In order to confirm the obtained low cycle fatigue behavior is correct, the fatigue life prediction of drilled flat bar specimen under cyclic four points bending load was conducted. Test results showed that the low cycle fatigue characteristics could be evaluated by developed fatigue tester. Moreover, the fatigue life of flat bar specimen was well predicted by the Miner’s Cumulative Damage Rule．Test results showed that the low cycle fatigue characteristics could be evaluated by developed fatigue tester. Moreover, the fatigue life of flat bar specimen was well predicted by the proposed procedure.
