Incoloy 800HT (UNS N08811) is a high-temperature alloy primarily composed of nickel, iron, and chromium, with small additions of aluminum, titanium, and copper. This Incoloy 800HT Pipe is specifically designed to offer excellent resistance to oxidation, carburization, and sulfidation at elevated temperatures. The "HT" in the alloy 800HT name stands for "high temperature," indicating its suitability for use in environments with elevated temperatures.
Incoloy 800HT N08811 Material
Incoloy 800HT is a nickel-iron-chromium alloy that is highly resistant to oxidation, corrosion, and high-temperature environments. This Alloy 800 HT / 1.4959 material is commonly used in industries such as chemical, petrochemical, and power generation due to its excellent mechanical properties and resistance to thermal fatigue.
N08811 is the ASTM designation for Incoloy 800HT and is used to identify the material in various applications. This n08811 material is often used to create pipes, tube fittings, valves, and other components that require high strength and corrosion resistance in elevated temperature environments.
ASTM B407 Incoloy 800HT Pipe Material Properties
Incoloy 800HT pipes are particularly useful in high-pressure applications due to their ability to withstand extreme temperatures without deformation or cracking. These ASME SB 407 UNS N08811 seamless pipes are often used in chemical plants and refineries for processing highly corrosive substances.
One important aspect of using Incoloy 800HT pipes is their ability to resist oxidation and carburization in high-temperature environments. This is made possible by the material's high chromium content, which forms a protective layer of chromium oxide on the surface of the metal that prevents further oxidation.
Incoloy 800HT pipes are also highly resistant to thermal shock and cyclic oxidation, making them ideal for use in power generation settings. These properties make ASTM B407 UNS N08811 material an excellent choice for superheaters, reheaters, and other components that are exposed to high temperatures and corrosive gases.
