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 a “workhorse” of the industry. HAYNES^® 188 alloy later offered engine designers a much higher temperature advantage. HAYNES^® 230^® alloy has gained increased use because of its unexcelled combination of high-temperature strength and oxidation resistance plus improved thermal stability.
