... corrosion results for UNS N08935 and UNS N06625 from three months exposure in natural seawater at 30°C and in chlorinated seawater at 45°C, 50°C and 80°C. The results indicate that UNS N08935 could be a stainless steel solution in seawater applications where more expensive nickel base alloys are used today...

...Abstract Nickel base alloys are widely used in high temperature oxidative atmospheres, such as heat exchangers and land-based gas turbines. To mitigate the deleterious effects of oxidation, chromium and aluminum additions, which promote the development of a protective layer of chromia or alumina...
