Use of the new superferritic stainless steels in contact with less corrosion resistant alloys in seawater may require the use of cathodic protection to prevent galvanic attack. Improperly applied cathodic protection can itself produce serious problems including hydrogen embrittlement. The effects of cathodically-generated hydrogen on the behavior of AL 29-4C™ ferritic stainless steel are presented. Potential limits and some guidelines for the safe use of cathodic protection with AL 29-4C alloy in seawater are presented.
