High Temperature Alloys

High temperature resistance is essential in many applications. Gas turbines, fuel nozzles, heat treating fixtures, and furnace muffles. These materials must stand up to high heat, extreme oxidation potential and cycling.

Hayens Alloy 25

Excellent strength for continuous service to 1800°F. Oxidation and carburization resistance to 1900°F. Galling resistant, with resistance to marine environments, acids and body fluids. Non-magnetic, even when severely cold reduced, can reach Rc 50 when cold reduced and aged. Resistant to hydrochloric and nitric acid at certain concentrations and temperatures, and wet chlorine environments at room temperature.

Gas turbine engine components : combustion chambers, and afterburners. Other uses also include :high temperature ball bearing service, springs, and heart valves.

Nitronic 60

High strength fully Austenitic alloy that resists galling and wear. Significantly lower cost to extend part life and lower maintenance. The yield strength is twice that of 304 and 316 stainless steels, in the annealed condition. Tensile strengths can be produced in excess of 200 ksi. Chloride pitting is superior to that of type 316, and the oxidation resistance is similar to type 321 at elevated temperatures, and excellent cryogenic impact strength.

Inconel 600

High nickel, high chromium content for resistance to oxidizing and reducing environments; for severely corrosive environments at elevated temperatures. Good oxidation resistance to 2150°F. Good formability. Furnace muffles, electronic components, chemical and food processing equipment, heat treating equipment, nuclear steam generator tubing.

Inconel 601

Nickel, higher chromium content for better resistance to oxidizing and reducing environments; for severely corrosive environments at elevated temperatures.

Good oxidation resistance to 2200°F. Good formability. Instrument probes, furnace muffles, electronic components, chemical and food processing equipment, heat treating equipment, nuclear steam generator tubing.

Inconel 718

Excellent strength from -423 degrees F to 1300 degrees F (-253 degrees C to 705 degrees C). Age hardenable and may be welded in fully aged condition, Excellent oxidation resistance up to 1800 degrees F (980 degrees C). Jet engines, pump bodies and parts, rocket motors and thrust reversers, nuclear fuel element spacers, hot extrusion tooling.

Hastelloy X

Excellent high temperature strength and oxidation resistance to 2200°F. Excellent forming and welding characteristics. Resistance to oxidizing, reducing, and neutral atmospheres. Resistant to SCC in petrochemical applications. Good ductility after prolonged service temperatures of 1200, through 1600°F for 16,000 hours. Gas turbine combustion cans and ducting, heat-treating equipment, spray bars, flame holders, furnace rolls, furnace baffles, and flash drier components.
