摘要：
Biofouling induced corrosion of stainless steels grades UNS 531603 and UNS 531254 was investigated at three sites off Singapore for 30 months. No corrosion was observed on grade UNS 531254, while the propensity for corrosion by shellfish of UNS 531603 is ranked as oyster > > barnacles > > green mussels. Oysters caused extensive localised corrosion, penetrating 2 mm thick plates with 12 months with tracks of corrosion several centimetres long. Shallow crevice corrosion was observed under dead barnacles, with an explanation presented for why corrosion is more severe under dead barnacles than live ones. Green mussels did not cause any corrosion.
