ASTM B163 / ASME SB163 UNS N08810 / Incoloy 800H Seamless Nickel Alloy Tube
ASTM B163/ASME SB163 is the standard specification for seamless nickel and nickel-alloy condenser and heat-exchanger tubes. UNS N08810, commonly known as Incoloy 800H, is a nickel-iron-chromium alloy optimized for high-temperature performance through controlled carbon content and stabilization. The material 800H / UNS N08810 is the go-to choice for high-temperature, high-stress applications where corrosion resistance, thermal stability, and long-term durability are essential. It bridges the gap between stainless steels and more expensive nickel alloys, offering exceptional performance in demanding thermal and chemical environments.
Why Choose SB163 Incoloy 800H Tube?
Seamless construction ensures higher pressure integrity and reliability
Compliant with ASME Boiler and Pressure Vessel Code for critical service
Suitable for both corrosive and high-temperature environments
Available in a range of sizes and schedules for custom engineering needs

Mian Features of Incoloy 800/ 800H/ 800HT three alloys.
1. Corrosion Resistance
Excellent and consistent oxidation, carburization, and sulfidation resistance at high temperatures.
High nickel content provides strong resistance to stress corrosion cracking, especially in chloride environments.
Well-suited for aggressive chemical and high-temperature aqueous applications.
2. High-Temperature Stability
Maintains structural integrity under extreme heat through solid-solution strengthening and creep resistance.
High melting point and controlled thermal expansion prevent deformation.
Protects against degradation, ensuring durability in thermally demanding environments.
3. Resistance to Carburization
Specifically designed to inhibit carbon diffusion in high-temperature, carbon-rich atmospheres.
Optimized alloy composition and surface passivation provide long-term protection against carburization.
Preserves material integrity and extends service life in applications such as furnace components and reformer tubes.
