Incoloy 825

Incoloy 825 is an all-purpose project alloy, have good corrosion resistance of the acid and alkali metal property in both oxidation and reduction environments. Incoloy 825 High nickel content made it with effective stress corrosion cracking resistance performance. Incoloy 825 have excellent corrosion resistance in different kinds of media, such as sulfuric acid, phosphoric acid, nitric acid and organic acid, alkali metal such as sodium hydroxide, potassium hydroxide, and hydrochloric acid. A variety of media corrosion of nuclear-burning dissolver show Incoloy 825 high integrated prpperty, like sulfuric acid, nitric acid and potassium hydroxide are all dealing in a same device.

Incoloy 825 is the face-centered cubic lattice structure.

Incoloy 825 is a nickel-iron-chromium alloy with additions of copper, molybdenum and titanium. The alloy's chemical composition is designed to provide exceptional resistance to many corrosive environments. The nickel content is sufficient for resistance to chloride-ion stress corrosion cracking. The nickel, in conjunction with the molybdenum and copper, also gives outstanding resistance to reducing environments such as those containing sulfuric and phosphoric acids. the molybdenum also aids resistance to pitting and crevice corrosion. The alloy's chromium content confers resistance to a variety of oxidizing substances such as nitrates, nitric acid and oxidizing salts. The titanium addition serves, with an appropriate heat treatment, to stabilize the alloy against sensitization to intergranular corrosion. The resistance of Incoloy 825 to general and localized corrosion under diverse conditions gives the alloy broad usefulness.

Applications include chemical processing, pollution control, oil and gas recovery, acid production, pickling operations, nuclear fuel reprocessing and handling of radioactive wastes.

Incoloy 825 is a nickel-iron- chromium alloy with titanium, copper, and molybdenum. Incoloy 825's chemical composition provides great resistance to many corrosive environments, such as pitting, crevice corrosion, intergranular corrosion, and stress- corrosion cracking.
