Abstract Corrosion results of 5 types of stainless steels ex posed to tidal zone at Qingdao,Xiamen and Yulin Sea area of China were reported. Corrosion behavior and rule of stainless steels in tidal zone was summarized.The stainless steels exposed to tidal zone were attacked by pitting and crevice cor rosion.It was found that pitting rates of stainless steels in tidal zone were bi gger during 1 to 4 years,after which the pitting rate diminished.The stainless s te el that had good pitting resistance in tidal zone possessed good resistance to c revice corrosion.Corrosion rate of stainless steels increased with going up of s eawater temperature of test sites.Increasing Cr content and adding Mo can enhanc e obviously corrosion resistance of stainless steels in tidal zone.Ni improv es corrosion resistance,but its improving effect is less.Fouling organism could cause localized corrosion of stainless steels.Effect of the fouling on corrosion of stainless steels in tidal zone was notable.
