The compressive residual stress, which is inducing by shot peening process, has the effect of increasing the intrinsic fatigue strength of surface and therefore would be beneficial in reducing the probability of fatigue damage. However, it was not known that the effect of shot peening in corrosion environment. In this study, the influence of shot peening and corrosion condition for corrosion property was investigated on immersed in supply water, 1% NaCl, 1% H₂SO₄. The immersion test was performed with two kind of specimen. The immersion periods was performed 4320hour(180days). Corrosion potential, weight loss were investigated from experimental results. From test results, the effect of shot peening on the corrosion characteristics was evaluated.
