Haynes International. Synonymous with high-performance alloys.

Our broad alloy portfolio enables customers to achieve higher efficiencies, reduce pollution levels, extend product life, and reduce costs. Our corrosion-resistant alloys are generally distinguished by the HASTELLOY^® brand and our high-temperature family of alloys are generally distinguished by the HAYNES^® brand. Industries often specify alloys by a UNS designation, unaware that such alloy specifications only address issues of chemical composition, not corrosion or heat resistance. We protect the alloys’ quality and assure their performance by focusing on precise control of chemical composition and thermo-mechanical processing, in addition to systematic testing. In our world, there’s no room for almost.

High-temperature Alloys

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.

Corrosion-resistant Alloys

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.

B-3^® alloy possesses outstanding resistance to non-oxidizing acids, such as hydrochloric acid and sulfuric acid. The advantages of B-3^® alloy over previous B-family alloys are enhanced thermal stability and improved fabrication characteristics. A new alloy, HASTELLOY^® HYBRID-BC1^® alloy will handle stronger non-oxidizing acids than C-type alloys and will tolerate oxidizing impurities that B-type alloys will not.

The most versatile of the HASTELLOY^® alloys are the “C-type” alloys. C-2000^® alloy combines outstanding resistance to oxidizing media with superior resistance to non-oxidizing environments and represents a true performance breakthrough for chemical process equipment applications. C-22^® alloy is particularly resistant to pitting and crevice corrosion; it has been used extensively to protect against the most corrosive FGD systems and the most sophisticated pharmaceutical reaction vessels.

G-30^® alloy has been very successful as phosphoric acid heat exchanger tubing and for other process components in the fertilizer industry. G-35^® alloy was designed as an improved version of G-30^® alloy in these applications.  The high chromium content of both of these alloys make them the premier choices for strong oxidizing solutions and mixed acid pickling services.
