Incoloy 825 is a nickel-iron-chromium alloy with additions of molybdenum, copper and titanium. This nickel steel alloy’s chemical composition is designed to provide exceptional resistance to many corrosive environments,that is designed to last, even under extreme operating conditions. This powerful nickel alloy is considered the forerunner of alloys containing molybdenum, the inclusion of which lends the material additional strength.In particular, in the chemical processing industry, Incoloy 825 is similar to alloy 800 but has improved resistance to aqueous corrosion.
