ASTM B407 NO8811 800HT Nickel Based Alloy Pipe ASTM B407 NO8811 800HT is a nickel-based alloy pipe specification. It is commonly used in high-temperature applications where resistance to oxidation and corrosion is required. This alloy is composed of nickel, chromium, and iron, with small amounts of other elements such as aluminum, titanium, and carbon.
The ASTM B407 specification covers seamless pipes made from this alloy, which are typically used in industries such as chemical processing, power generation, and aerospace. These pipes are known for their excellent mechanical properties, high strength, and good thermal stability.
The NO8811 designation refers to the specific grade of the alloy, which has a chemical composition that meets the requirements specified by ASTM B407. The 800HT grade offers enhanced creep resistance and improved resistance to carburization and nitridation compared to other nickel-based alloys.
Overall, ASTM B407 NO8811 800HT nickel-based alloy pipes are widely used in high-temperature applications due to their excellent resistance to oxidation and corrosion, as well as their high strength and thermal stability.
