INCOLOY 800H (UNS N08811) is designed for superior high-temperature performance compared to standard INCOLOY 800. Its increased carbon content (0.05-0.10%) and optimized grain size improve its resistance to creep and stress-rupture deformation, making it ideal for long-term service in applications exposed to extreme heat and mechanical stress.
The alloy's balanced nickel-chromium-iron composition ensures excellent resistance to oxidation, carburization, and sulfidation, while maintaining structural stability even after prolonged exposure to elevated temperatures. INCOLOY 800H also offers good resistance to chloride stress-corrosion cracking, making it suitable for aggressive environments.
INCOLOY 800H offers outstanding durability and thermal stability, making it the material of choice for industries where prolonged exposure to extreme heat and corrosive conditions demands superior creep strength, oxidation resistance, and long-term reliability.
