In the period from 1980, highly alloyed stainless steels (i.e. Pitting Resistance Equivalent (PRE{sub N}) > 40) have been widely selected for chlorinated sea water systems in the Norwegian offshore industry. Recently failures have been reported -- severe crevice corrosion on flanges in a cooling water system and crevice corrosion at the threaded cast and forged joints in a fire water system. The failures highlights the question of corrosion testing and safe use limits for high alloyed stainless steels in sea water systems. This paper discusses three aspects regarding testing and selection of highly alloyed stainless steels for sea water application -- the relevancy of the electrochemical test methods used, the quality control system and the importance of repassivation.
