Alloy 617 is a nickel-chromium-cobalt-molybdenum alloy.With an exceptional combination of metallurgical stability, strength, oxidation resistance at high temperatures and resistance to oxidation is enhanced by an aluminum addition, the alloy also resists a wide range of corrosive aqueous environments. 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.
