Inconel 800HT is a high-temperature alloy that belongs to the family of nickel-iron-chromium alloys. It is a modification of Inconel 800, with higher levels of carbon, aluminum, and titanium, which gives it improved high-temperature strength and excellent corrosion resistance.

The "HT" in Inconel 800HT stands for "High Temperature," and this alloy is specifically designed for use in applications that require high strength and excellent resistance to oxidation and carburization at elevated temperatures.

Inconel 800HT can be used in a wide range of industries, including the chemical processing, petrochemical, and power generation industries. It is commonly used in furnace components, heat exchangers, and piping systems for high-temperature corrosive environments.

This alloy has a high level of thermal stability and can withstand temperatures up to 1100°C (2000°F) for prolonged periods without any significant degradation. Inconel 800HT also has excellent resistance to sulfur-bearing gases, which makes it suitable for use in applications where sulfuric acid is present.

Overall, Inconel 800HT is a high-performance alloy with excellent high-temperature strength and corrosion resistance, making it an ideal material for use in demanding industrial applications.
