Incoloy 800 is a nickel‑iron‑chromium alloy with excellent high‑temperature oxidation, carburization, and corrosion resistance. It exhibits stable mechanical properties at both room and elevated temperatures, along with good creep strength and formability. It offers reliable resistance to stress corrosion cracking in high‑temperature water and steam environments. With good weldability and structural stability under thermal cycling, it is widely used in high‑temperature and corrosive industrial applications requiring long‑term durability.
