What Haynes International does

Haynes International, Inc. is a Kokomo, Indiana-based developer, manufacturer, and global distributor of high-performance nickel- and cobalt-based alloys sold under the HASTELLOY® and HAYNES® brand families. Founded in 1912 by Elwood Haynes, the company operates from a single-entity primary manufacturing footprint in Indiana (Kokomo and LaPorte) augmented by nine additional service and sales offices across North America, the UK, Switzerland, China, Japan, and Singapore. Its wrought alloy portfolio spans more than 50 registered grades covering three families: high-temperature alloys (e.g., HAYNES® 230, 282, 625, 718, Waspaloy, X) for aerospace turbines, power generation, and industrial heating; corrosion-resistant alloys (e.g., HASTELLOY® C-276, C-22, B-3, N, and the recently launched WR-66®) for chemical processing and pollution control; and titanium alloys for aerospace. The company sells product in standard mill forms (sheet, plate, wire, pipe and tubing, bar and billet, fittings and flanges) and through value-added processing services (cutting, waterjet, laser, plasma, EBW, brazing, and heat treatment).

Core offering

Haynes International develops, manufactures, and globally distributes high-performance nickel- and cobalt-based alloys under the HASTELLOY® and HAYNES® brands, offered in product forms including sheet, plate, wire, welding products, pipe, tubing, bar, billet, fittings, and flanges. The company also provides value-added processing services (cutting, heat treatment, welding, brazing) at its service centers, alongside technical resources such as a Corrosion Guide, Welding SmartGuide, and Technical Library to support alloy selection, fabrication, and application engineering for customers in aerospace, power generation, chemical processing, and industrial markets.

Product overview

Haynes International is a manufacturer and distributor of HASTELLOY® and HAYNES® branded high-performance alloys. The portfolio consists of three main alloy families: high-temperature alloys (nickel- and cobalt-based alloys for aerospace turbine, power generation, and industrial heating applications), corrosion-resistant alloys (nickel-molybdenum and nickel-chromium alloys for chemical processing, pollution control, and marine environments), and titanium alloys (for aerospace and industrial applications). Product forms include sheet and plate, wire and welding products (TIG/MIG filler metals, coated electrodes, thermal spray, medical wire, small bar), pipe and tubing (welded and seamless), bar and billet, and fittings and flanges. The company also provides fabrication services including welding and joining guidance (GTAW/TIG, GMAW/MIG, SMAW/stick, plasma arc welding, electron beam welding, laser beam welding, brazing and soldering), heat treatment, machining, grinding, and descaling/pickling. Technical services include a Corrosion Guide, Welding SmartGuide web application, Technical Library, and alloy selection consulting. Haynes International is a member of the Acerinox group.

Partnerships

Two partnerships are on record, tiered flagship and core.

• AcerinoxflagshipOthersAcerinox completed the acquisition of Haynes International in 2024 for $970 million. Haynes International operates as a member of the Acerinox group, maintaining its brand portfolio of HASTELLOY® and HAYNES® alloys while benefiting from Acerinox's global stainless steel and high-performance alloys platform. Acerinox is evaluating a separate NYSE listing for Haynes International's US operations.
• Energy Industries of Ohio (ComTest)coreStrategic or Co-development PartnerHaynes International is a partner in the Component Test Facility (ComTest) project led by Energy Industries of Ohio, along with partners EPRI, GE, PCC, and MetalTek. The project is part of NETL's High Performance Materials Program advancing the nation's high-temperature materials manufacturing supply chain for fossil energy power generation efficiency. The project covers operating tiers from Subcritical through Advanced Ultra Supercritical (AUSC).

Direct peers

• VDM Metals: Acerinox group sister company producing nickel-based alloys and corrosion-resistant specialty steels; shares the same parent and competes directly with Haynes in chemical processing and power generation segments.
• Special Metals Corporation: A Precision Castparts subsidiary and the closest direct competitor to Haynes' HASTELLOY® nickel-based corrosion-resistant and high-temperature alloy portfolio, serving the same aerospace, chemical processing, and power generation customers with overlapping nickel-cobalt superalloy grades.
• Carpenter Technology Corporation: Specialty alloys manufacturer with direct overlap in nickel and cobalt high-temperature superalloys for aerospace and chemical processing; similarly operates a global service-center network and competing trademarked alloy families.
• Allegheny Technologies (ATI): Specialty materials producer serving aerospace, chemical, and energy end-markets with a broader portfolio spanning nickel alloys, titanium, and stainless steel; explicitly identified alongside Haynes in third-party market analyses of the global iron-nickel alloys market.

Broad incumbents

• Aperam: European stainless and specialty alloys manufacturer named in Haynes' competitive set, with broader stainless steel and electrical steel portfolio but overlapping presence in nickel alloy products for industrial markets.
• Thyssenkrupp: Diversified German industrial conglomerate with materials and steel divisions producing specialty alloys serving similar aerospace, chemical, and industrial gas turbine customers as Haynes; larger scale but less focused on the premium superalloy niche.
• Howmet Aerospace: Aerospace superalloy casting and components manufacturer serving aircraft engines, industrial gas turbines, and defense; consumes Haynes-class alloys but competes in adjacent downstream components rather than as a direct alloy supplier.

Others

• Precision Castparts Corp (PCC):

Emerging players

• Doncasters Group: Specialty superalloy castings and components manufacturer for aerospace engines and industrial gas turbines; partial overlap with Haynes in high-temperature alloys but focused on cast components rather than wrought mill products.
• Cannon Muskegon: Specialty superalloy producer focused on nickel-based vacuum-melted alloys for aerospace, industrial gas turbines, and high-temperature applications; narrower portfolio than Haynes but overlapping metallurgy niche.
