Abstract	This paper investigates the galvanic coupling behaviours of carbon steel and three different stainless steels (304LN, 316LN and 2205). The results indicate that the oxygen reduction reaction is a ratedeterminingstep and is much lower on stainless steel than on passive carbon steel. Therefore, the galvanic coupling current between stainless steel and corroding carbon steel is lower than the coupling current between passive and corroding carbon steels. Consequently, the combination of stainless steel with carbon steelwill not increase the risk of corrosion of carbon steel.
