Incoloy 800 |UNS N08800|1.4876 Seamless Pipe
Our Incoloy 800 pipes are designed to maintain a stable austenitic structure, offering superior resistance to sulfidation and nitriding even under prolonged exposure to high temperatures. With advanced cold-drawing and vacuum heat treatment processes, we ensure every pipe delivers optimal creep strength and thermal stability for chemical processing, power generation, and industrial furnace systems. Tengqi provides a comprehensive range of schedules and sizes, backed by rigorous quality testing to guarantee reliable performance in demanding industrial applications.
SeamlessIncoloy 800 Pipe (Incoloy800 / UNS N08800 / W.Nr. 1.4876) is a nickel-iron-chromium alloy with high creep rupture strength and resistance to oxidation. Manufactured by Tengqi in Fujian, China, every heat is fully traceable, hydro-tested and available with third-party inspection (SGS / BV / TUV) on request.
