Corrosion resistant alloys

Inconel 617

 

Inconel 617 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. It is widely used in gas turbines for combustion cans, ducting and transition liners; petrochemical processing; heat-treating equipment; and in nitric acid production.
