Incoloy 800HT Nickel Alloy Pipe (UNS N08811)
Incoloy 800HT is a high-temperature, nickel-iron-chromium alloy with excellent oxidation and carburization resistance. It is a modified version of Incoloy 800, with tighter chemical composition controls and enhanced high-temperature strength due to increased titanium and aluminum content. Incoloy 800HT pipes are ideal for extreme heat and corrosive conditions, making them a top choice for industries requiring durable, high-performance piping solutions
Key Features of Incoloy 800HT Pipes
- High-Temperature Resistance: Performs well in temperatures up to 1500°F (815°C).
- Corrosion Resistance: Resistant to oxidation, carburization, and sulfidation in harsh environments.
- Mechanical Strength: Maintains strength and creep resistance at elevated temperatures.
