Incoloy 800 |UNS N08800|1.4876 Seamless Tube

Incoloy 800 Seamless Pipes (UNS N08800 / W.Nr. 1.4876) are high-integrity nickel-iron-chromium solutions engineered for exceptional structural stability and resistance to oxidation and carburization in extreme thermal environments. As a specialized manufacturer based in Fujian, China, Tengqi produces precision-engineered seamless tubing that strictly complies with ASTM B407, ASME SB407, and EN 10216-5 international standards.

Our Incoloy 800 tubes are designed to maintain a stable austenitic structure, offering superior protection against sulfidation and nitriding during prolonged exposure to elevated temperatures. Ideal for heat exchangers, power generation, and petrochemical processing, these pipes provide optimal creep strength and thermal durability. Through advanced cold-drawing and vacuum heat treatment, Tengqi ensures every pipe meets stringent quality benchmarks, backed by comprehensive technical data—including chemical composition and mechanical properties—to support your precision engineering requirements.
