Luois Metals provides Haynes 617 rods and bars from our Houston operation to the aerospace, power generation, and petrochemical industries. Haynes 617 is a nickel-chromium-cobalt-molybdenum superalloy that exhibits high strength and resistance to oxidation through 1850°F (1010°C). We supply rods and bars according to AMS 5984 and ASTM B637 with full heat certification and traceability. We stock a variety of diameters and tempers, supported by precision processing services. Luois Metals provides timely, high-integrity alloy parts optimized for extreme-temperature duty and engineered to accommodate advanced thermal systems.
Haynes 617 contains about 52% nickel, 22% chromium, 12% cobalt, and 9% molybdenum, along with iron and trace elements. It possesses excellent tensile strength to 965 MPa, yield strength of about 625 MPa, and elongation about 25% (solution-treated). Brinell hardness varies between 200–300 HB. It retains oxidation resistance up to 1010 °C and demonstrates excellent tensile strength up to ~750 °C. AMS and ASTM certified, 617 is weldable as well as having creep strength, which allows it to be used for welded assemblies in harsh environments.
Yes, Haynes 617 rods can be customized in both size and length according to specific requirements. Customization is available through manufacturers or suppliers who offer tailored solutions.
Haynes 617 bars and rods offer excellent performance in high-temperature environments, with outstanding oxidation and corrosion resistance, maintaining strength and stability up to 1,250°C (2,300°F), making them ideal for aerospace and industrial applications.
To maintain Haynes 617 bars, avoid exposure to high temperatures for extended periods, regularly clean with non-abrasive methods, and inspect for corrosion or wear to ensure optimal performance and longevity.
Haynes 617 rods and bars find applications in the components of a gas turbine, such as combustor liners, transition ducts, and blade platforms. They‘re appropriate for rocket-engine thrust chambers, nuclear reactors, and heat exchanger tube sheets. In petrochemical processing, 617 alloy sustains reformer tubes, polymerization reactors, and furnace components. Its strength at high temperatures and weldability also has applications in metallurgical fixtures and forging dies. Industries that need high-temperature structural components with good reliability—like aerospace, petrochemical, and advanced-power systems—appreciate Haynes 617 for thermal cycling, corrosion, creep, and mechanical stress toughness.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
