ASTM B407 Alloy 800HT / UNS N08811 Seamless Nickel Alloy Steel Pipe

ASTM B407 UNS N08811 DIN 1.4959 / INCOLOY 800HT SEAMLESS ALLOY STEEL PIPE

Alloy 800HT are high-performance alloys that belong to the Incoloy family, which are nickel-chromium-iron alloys known for their excellent high-temperature strength and oxidation resistance. It is known for its excellent resistance to oxidation and carburization, making it ideal for applications in high-temperature environments. 

Here are some key characteristics of Alloy 800HT seamless tube:

1. High-Temperature Strength: Alloy 800HT maintains strength at elevated temperatures, making it suitable for use in furnace applications and heat exchangers.

2. Oxidation and Carburization Resistance: The alloy's high nickel and chromium content provide substantial resistance to oxidation and carburization, extending its lifespan in harsh environments.

3. Corrosion Resistance: While it is not completely immune to corrosion, Alloy 800HT offers good resistance against various corrosive media, particularly in high-temperature conditions.

4. Fabricability: The alloy can be easily processed through a variety of methods, including welding, machining, and forming, allowing for versatile usage.

5. Thermal Stability: It shows good stability across a range of temperatures, which is essential for applications that experience fluctuating temperatures.
