Luois Metals supplies Haynes 556 bars and rods from our inventory located in Houston to aerospace, oil & gas, and power generation industries. Haynes 556 is an iron-chromium, nickel-based superalloy, possessing superior oxidation and thermal fatigue resistance. We carry rods in a variety of sizes, processed according to AMS 5725 and ASTM B637, along with certifications. Our Houston plant provides precision cutting, heat treating, and technical service. Luois Metals guarantees timely delivery of Haynes 556 products, used in applications where extreme heat employs component integrity during thermal cycling.
Haynes 556 contains about 30% nickel, 23% chromium, 20% iron, and 4% niobium with minor amounts of molybdenum, aluminum, and titanium. Haynes 556 is a γ’ strengthened superalloy with tensile strength of about 950 MPa, yield strength of about 600 MPa, and elongation of about 20%. It has Brinell hardness of 230–280 HB and good thermal fatigue endurance. Haynes 556 is capable of functioning at temperatures of about 704°C, checking all the boxes for creep strength and oxidation resistance. It is AMS 5725 / ASTM B637 certified and finds fame due to weldability and high thermal stability.
Haynes 556 bars typically come with a rough finish as standard, but they can also be supplied with a smooth finish upon request, depending on customer specifications and applications.
Yes, Haynes 556 rods can be customized in size and length according to specific requirements, offering flexibility for various applications in industries needing high-performance materials.
Haynes 556 bars and rods perform excellently in high-temperature environments, offering superior resistance to oxidation, corrosion, and thermal fatigue, making them ideal for applications in extreme heat and harsh conditions.
Haynes 556 rods and bars find applications in turbine parts like hot gas path components, transition ducts, combustion chamber liners, and blade platforms. They are also suitable for nozzles, seals and structural parts subjected to thermal cycling in aerospace engines. In oil & gas, 556 alloy is applied to hot section nozzle hardware and valves. Its applications also include high temperature industrial furnaces and thermal processing systems. The weldability, the extreme heat conditions due to thermal fatigue resistance of alloy, and oxidation stability combine to make it critical where there is repeatable performance under fluctuating extreme-heat conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
