Some of the authors have been continually researching the effect of plastic deformation on fatigue properties and considerably clarified that it is one of the effective and low cost way to improve the fatigue properties. In this study, fatigue test had been performed to investigate the effect of roller working on notched specimen using eutectoid steel-one of the most important materials for industrial components. The result of the test shows that the cold rolling improved the fatigue limit of this kind of material significantly. The fatigue limit of roller-worked specimen does not necessarily increase with the increase in plastic deformation value. There exists an optimum value by roller working for improving the fatigue strength. The fracture surface is observed with SEM, the residual stress was measured by X-way method and the reason of the improvement is analyzed in the paper.
