Alloy 617 Description

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.

Alloy 617 can be cold rolled to achieve the temper properties required by specific customers and/or manufacturing requirements. Contact Ulbrich Wire for details.

Additional Properties

Corrosion Resistance

Refer to NACE (National Association of Corrosion Engineers) for recommendations.

Standard Wire Finishes

Extra Clean: Extra clean is also referred to as “bright annealed” or “bright annealed and cold rolled”

Grease (round wire only): Drawn in a heavy grease produces an “Ultra bright” finish for decorative applications

Soap (round wire only): Soap is used as a lubricant in the drawing process and is not removed. It acts as a lubricant during customer part forming operation.

A soap finish is available in tempered products.

Plated: Many plating options are available.
*Special finishes are available: Contact Ulbrich Wire Sales with special finish and plating requests.
