Abstract
Localized corrosion of high-alloy steel in seawater, mainly under crev ices, limits the alloys' use in such environments. An in-situ test pro gram was conducted to study this corrosive process and possible protec tive measures. Attention focused on the resistance of several types of high-alloy steels under corrosive conditions and on the response of t ype 316 stainless steel to cathodic protection (CP) by carbon steel an d zinc anodes. It was found that CP could effectively mitigate crevice corrosion in these subsea conditions.
