Abstract Biofouling induced corrosion of stainless steels grades UNS S31603 and UNS S31254 was investigated at three sites off Singapore for 30 months. No corrosion was observed on grade UNS S31254, while the propensity for corrosion by shellfish of UNS S31603 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.

新加坡海水中宏观污垢引起不锈钢局部腐蚀

摘要 在新加坡附近的三个地点对不锈钢等级 UNS S31603 和 UNS S31254 的生物污垢引起的腐蚀进行了 30 个月的调查。等级 UNS S31254 没有观察到腐蚀，而 UNS S31603 的贝类腐蚀倾向被列为牡蛎 >> 藤壶 >> 绿贻贝。牡蛎造成了广泛的局部腐蚀，在 12 个月内穿透了 2 毫米厚的板，腐蚀痕迹长达几厘米。在死藤壶下观察到浅裂缝腐蚀，并解释了为什么死藤壶下的腐蚀比活藤壶更严重。青口贝没有引起任何腐蚀。
