Abstract
The corrosion resistance of any alloy is determined by the character of the surface it presents to the environment. Changes to the surface, such as chromium depletion, can reduce the alloy’s corrosion resistance from the expected value. In actual practice, determining through analytical means whether chromium depletion is present is challenging. Experience with the 6-Mo superaustenitic alloy N08367 in marine and marine-substitute environments will be used to demonstrate analytical and performance-based methods of assessing chromium depletion. The practical implications of Cr-depletion will be addressed.
