The Incoloy 800HT (UNS N08811) Pipes and tubes are the most commonly used material to make different components to work in high-temperature and corrosive environments. It's made up of different elements such as nickel, iron, chromium, and other elements that provide exceptional strength and resistance. Incoloy 800HT UNS N08811 is made according to international quality standards, which is such as ASTM B407 and ASME SB514. It also performs well in the temperature range between 650 °C and 870 °C. They have higher creep strength and rupture strength than regular Incoloy 800 series due to the addition of controlled carbon, aluminum and titanium. They can be seamless or welded and are applied in many applications such as power generation, chemical processing equipment, heat treatment furnaces, and petrochemical plants. USA Piping Solution is a manufacturer and supplier of high quality Incoloy 800HT (UNS N08811) Pipes & Tubes that are manufactured through precision manufacturing, strict quality inspection and reliable worldwide delivery.
