The results of corrosion survey for stainless steel tanks used in water storage at various areas are presented. More severe corrosion is observed for the area with higher airborne salinity. Damages are revealed at both outer and inner surfaces for tanks made of Type 304 and 201 steels exposed in coastal conditions. Corrosion products examined by visual inspection and SEM-EDX technique showed relatively distinctive characteristics for the outer and inner tank surfaces which are attributed to different corrosion mechanisms initiated by corrosive chloride accumulated on steel surfaces. | Corrosion of stainless steel water storage tanks exposed in coastal atmospheric conditions
