Useful although cathodic protection required on critical surfaces
Monel 400 (nickel-copper alloy) Pits tend to be self-limiting in depth at about 1-6 mm.No protection required for heavy sections.Cathodic protection from steel or copper base alloys will prevent pitting on O Ring, valve seats, and similar critical surfaces.
