The resistance of commercial and laboratory produced stainless steels to crevice corrosion was evaluated by a 60-day exposure in filtered seawater at 25 C. The results in seawater were compared to laboratory tests in 10% FeCl/sub 3/. The results in seawater were compared to laboratory tests in 10% FeCl/sub 3/. Austenitic, ferritic, and duplex stainless steels containing a minimum of 25% Cr-5% Mo, 27% Cr-3.4% Mo and 25% Cr-3.2% Mo, respectively, were resistant to crevice corrosion in 25 C seawater. The austenitic stainless steels also required a minimum of 0.2% N. Significant reductions in either the chromium or molybdenum content caused substantial attack. There was a good correlation between the laboratory tests in 10% FeCl/sub 3/ and the seawater test for the ferritic and duplex stainless steels but not for the austenitic grades.
