In this paper, the results of 16-year exposure test of stainless steel in the fully leached zone, tidal zone and splash zone of the seawater are summarized, and the stainless steel is seriously corroded in the leaching zone, and the corrosion resistance varies greatly. In the tidal zone, the corrosion of the stainless steel is heavy and the corrosion resistance There is a clear difference in the splash zone, 2Cr13 can not maintain a passive state, poor corrosion resistance; containing more than 17% Cr stainless steel corrosion resistance is better, their corrosion resistance is not obvious difference. Marine biofouling can cause stainless steel Of the local corrosion, which has a significant impact on the corrosion of stainless steel in all immersion zone, tidal zone
