Description
Incoloy 800H is a high-strength, corrosion-resistant alloy primarily composed of nickel, iron, and chromium, with additional enhancements in its carbon content for improved high-temperature strength. This alloy is designed for service in environments where both oxidation and carburization are present at elevated temperatures, typically ranging from 1000°F to 1500°F (540°C to 815°C).
It excels in applications such as chemical processing, power generation, and petrochemical industries, where high-temperature stability and resistance to corrosion are crucial. Incoloy 800H’s excellent resistance to oxidation, sulfidation, and carburization makes it a preferred material for furnace components, heat exchangers, and nuclear reactors. Its mechanical properties, including high creep resistance and tensile strength, ensure reliable performance in demanding, high-temperature environments.
