Product Description
ASTM B409 Alloy 800HT (UNS N08811) Seamless Nickel Alloy Tube for High Temperature Service
Product Description
ASTM B409 Alloy 800HT is a nickel‑iron‑chromium alloy with controlled carbon, aluminum, and titanium for elevated‑temperature strength. It offers excellent creep‑rupture strength, oxidation resistance, and carburization resistance up to 1100°C. Widely used in furnace components, heat exchangers, petrochemical processing, and high‑temperature piping systems.
