Inconel 622 is a nickel-chromium-cobalt-molybdenum alloy with an exceptional combination of metallurgical stability, strength and oxidation resistance at high temperatures. Resistance to oxidation is enhanced by an aluminum addition. The alloy also resists a wide range of corrosive aqueous environments.
Inconel 622 is used in gas turbines for combustion cans, ducting and transition liners; for petrochemical processing; for heat-treating equipment; and in nitric acid production. Standard product forms are round, forging stock, extruded section, plate, sheet, strip, pipe, tube and wire.
