With its exceptional resistance to oxidation, carburization, and sulfidation, Incoloy 800HT is widely used in applications such as heat exchangers, furnace parts, petrochemical processing, superheaters, and power plants. This alloy maintains its structural integrity under prolonged exposure to elevated temperatures above 650°C (1200°F), making it the preferred material for high-stress, high-heat applications.
Incoloy 800HT is a nickel-iron-chromium alloy known for its exceptional high-temperature strength, creep resistance, and oxidation resistance. As an enhanced version of Incoloy 800 and Incoloy 800H, it features carefully controlled levels of carbon, aluminum, and titanium, optimizing its performance in extreme conditions.
