Incoloy 800 Pipe

Incoloy 800 pipe manufacturer in India
ISO Certified Manufacturer

Incoloy 800 pipe is a nickel-iron-chromium alloy pipe (UNS N08800) manufactured to ASTM B407 / ASME SB407, containing approximately 32–38% nickel, 19–23% chromium, and balance iron with controlled aluminum and titanium additions. This alloy provides good strength and excellent resistance to oxidation, carburization, and nitridation at elevated temperatures, with useful mechanical properties up to 980°C.

Incoloy 800 pipes are used in chemical processing, heat treatment furnace components, petrochemical reformer and cracker tubes, power generation steam generators, and industrial high-temperature applications where resistance to oxidation and carburization in both oxidizing and reducing atmospheres is essential.

Spark Steel supplies Incoloy 800 seamless pipes conforming to ASTM B407 / ASME SB407 (UNS N08800) in sizes from ½" to 8" NPS in annealed condition. Tensile strength minimum 520 MPa and yield strength minimum 207 MPa. Full traceability documentation including EN 10204 3.1 mill test reports, chemical composition, and mechanical test results. PMI testing and third-party inspection available on request.
