Description
Incoloy Alloy 800HT is a high-performance nickel-iron-chromium alloy designed for use in high-temperature and corrosive environments. With a composition optimized for oxidation and carburization resistance, it excels in applications involving elevated temperatures, typically between 1100°F (593°C) and 1600°F (871°C).
This alloy is especially noted for its exceptional resistance to thermal fatigue and creep, making it suitable for components such as heat exchangers, gas turbines, and furnace parts. The material’s strength at high temperatures is bolstered by its ability to withstand long-term exposure to harsh conditions without significant degradation, offering reliability in industries like chemical processing, power generation, and petrochemicals.
Compared to other high-temperature alloys, Incoloy 800HT offers superior long-term stability and resistance to oxidation, ensuring reduced maintenance and extended service life in critical applications.
