Chemical Composition

Incoloy 800 Pipes are nickel-iron-chromium alloy pipes designed for excellent oxidation, carburization, and high-temperature corrosion resistance. Available as ASTM B407 UNS N08800 seamless pipe, ASTM B514 Incoloy 800 welded pipe, Incoloy 800H UNS N08810 pipe, and 800HT UNS N08811 pipe, these pipes are widely used in petrochemical, heat treatment, power generation, and chemical processing industries.

Detailed Information

High-Quality Incoloy 800 Pipes | ASTM B407 UNS N08800 Pipe Manufacturer

We are a trusted manufacturer, supplier, stockist, and exporter of Incoloy 800 Pipes manufactured to international quality standards for demanding industrial applications. Our piping products deliver exceptional resistance to oxidation, carburization, and stress corrosion cracking while maintaining excellent mechanical strength at elevated temperatures.

Our inventory includes ASTM B407 UNS N08800 seamless pipe, ASTM B514 Incoloy 800 welded pipe, Incoloy 800H UNS N08810 pipe, 800HT UNS N08811 pipe, Incoloy 800 cold drawn seamless pipe, Incoloy 800 ERW / EFW pipe, and Incoloy 800 schedule 40 pipe in multiple diameters, wall thicknesses, and lengths.

Manufactured from high-quality nickel-iron-chromium alloy, these pipes are extensively used in refineries, chemical plants, heat exchangers, pressure vessels, power plants, and furnace components where superior performance under continuous high temperatures is essential.

What are Incoloy 800 Pipes?

Incoloy 800 Pipes are high-performance nickel alloy pipes containing approximately 30–35% nickel and 19–23% chromium with balanced iron content. The alloy provides outstanding resistance against oxidation, sulfidation, carburization, and aqueous corrosion while maintaining excellent mechanical properties from cryogenic temperatures to approximately 1100°F (593°C).

For higher creep and rupture strength, industries often select Incoloy 800H UNS N08810 pipe or 800HT UNS N08811 pipe, which are optimized for elevated temperature service in demanding environments.

International material equivalents include 1.4876 Incoloy 800 equivalent pipe and GOST ЭИ670 Incoloy 800 piping, making these alloys widely accepted across global engineering projects.
