Abstract
An electrochemical test has been used to evaluate the resistance to crevice corrosion in sea water of some commercial stainless steels. The results for established alloys correlate well with known service performance, and give confidence in the use of the technique to predict the behaviour of newer materials. A large variation in resistance to crevice corrosion was found for duplex alloys of the same nominal composition. The differences are thought to be a result of the addition of nitrogen as an alloying element and also the segregation of chromium and molybdenum between the ferritic and austenitic phases.
