Galvanic corrosion between coated carbon steel and austenitic stainless steel in (A) seawater immersion, and (B) marine atmosphere, offshore. In (A), the coated carbon steel seawater ballast pump discharge column was galvanically corroded by a stainless steel clip. In (B), 316 austenitic stainless steel instrumentation tubing is directly touching a coated carbon steel pressure vessel in a marine atmosphere offshore. Corrosion occurred at the point of contact for the same reason as in (A), and streaks of rust bleeding are visible.
