Incoloy 800H |UNS N08810|1.4876 Seamless Tube
Our Incoloy 800H tubes undergo specialized high-temperature annealing to ensure a controlled coarse grain size, providing superior structural stability in petrochemical processing, power generation, and industrial furnace systems. These seamless pipes offer outstanding resistance to oxidation, carburization, and sulfidation in extreme thermal environments. Through advanced cold-drawing and rigorous quality testing, Tengqi delivers certified, export-grade solutions that guarantee long-term reliability for critical high-temperature infrastructure.
SeamlessIncoloy 800H Tube (Incoloy800H / UNS N08810 / W.Nr. 1.4876) is the high-carbon Incoloy 800 with controlled grain size for elevated-temperature creep service. Manufactured by Tengqi in Fujian, China, every heat is fully traceable, hydro-tested and available with third-party inspection (SGS / BV / TUV) on request.
