耐熱合金

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. HAYNES® 242® alloy shows great promise for aircraft engine seal rings, containment rings, duct segments, casings and fasteners. The newest HAYNES® 282® alloy combines exceptional high temperature properties with good weldability and fabricability.

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® 214® alloy is gaining more and more applications in the ceramics, metalworking, automotive and electronics industries for “clean firing.”

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

The Corrosion-resistant HASTELLOY® alloys are widely used by the chemical processing industries. The need for reliable performance leads to their acceptance and growth in the areas of energy, health and environmental, oil and gas, pharmaceutical and flue gas desulfurization industries. The attributes of HASTELLOY® alloys include high resistance to uniform attack, outstanding localized corrosion resistance, excellent stress corrosion cracking resistance, and ease of welding and fabrication.
