Incoloy 800, 800H, and 800HT are high-performance nickel-iron-chromium alloys designed for applications in extreme environments, particularly those involving elevated temperatures. These alloys are part of the Incoloy family, known for their excellent corrosion resistance, high-temperature strength, and exceptional mechanical properties. Sheets, plates, coils, and shims made from these alloys find extensive use in various industries, including chemical processing, power generation, and aerospace.
Incoloy 800 is a solid solution-strengthened alloy with a high nickel content, providing excellent resistance to oxidation, carburization, and sulfidation. Its strength and corrosion resistance make it suitable for applications in nitric acid and organic acid processing. Incoloy 800 Coils and Shims are utilized in heat exchangers, furnace components, and petrochemical equipment.
Incoloy 800H Plates offer enhanced high-temperature properties due to controlled carbon, aluminum, and titanium levels. This modification results in improved creep and rupture strength at elevated temperatures. Incoloy 800H Sheets are employed in industrial furnaces, heaters, and petrochemical processing units where exposure to high temperatures is a concern.
