The aircraft gas turbine engine market has traditionally been the major user of HASTELLOY® and HAYNES® high-temperature alloys. Here the story has been one of incremental growth as each major advance in engine performance capitalizes on the development of newer and more efficient materials of construction.

MULTIMET® alloy was the first significant wrought HAYNES® high-temperature alloy offered to the aviation industry in the 1950's. HASTELLOY® X alloy, the next major development is still the "workhorse" of the industry. HAYNES® 188 alloy later offered engine designers a much higher temperature advantage. The newest HAYNES® 230® alloy is gaining increased use because of its unexcelled combination of high-temperature strength and oxidation resistance plus improved thermal stability. Also, the newer HAYNES® 242TM alloy shows great promise for aircraft engine seal rings, containment rings, duct segments, casings and fasteners.

Outside of the aircraft industry, high performance, heat-resistant alloys offer properties never before available. Because of its superior oxidation resistance through 2200°F (1204°C), HAYNES® 214TM alloy is gaining more and more applications in the ceramics, metalworking, automotive and electronics industries for "clean firing."

HAYNES® 556TM and HR-160® alloys have very good resistance in waste disposal and fossil energy production because of their superior resistance to oxidation, sulfidation and molten salt attack.

HAYNES® HR-120®, 230® and 556TM alloys are providing cost-effective solutions to many maintenance problems in the heat-treating and industrial heating industries because of their superior properties.
