Exposure test of stainless steel reinforced concrete specimens was conducted in severe chloride prone area in Japan Sea side. Visual observation was carried out every year. Specimens were dismantled and reinforcements ware investigated at three and ten years. It was found that normal reinforcements corroded when chloride content in concrete at the bar portion reached the threshold value in the JSCE standard specification. Thereafter, corrosion crack and its propagation were observed. Stainless steel reinforcements did not corrode even chloride content in concrete at the bar portion reached the threshold value in the JSCE recommendation. Contact corrosion of dissimilar metals was not observed in the conducted exposure test.
