Incoloy 800H

Incoloy 800H
Incoloy 800H is a nickel‑iron‑chromium alloy with controlled carbon and aluminum content, designed for enhanced high‑temperature creep strength. It offers excellent oxidation, carburization, and sulfidation resistance, along with stable mechanical properties under long‑term elevated temperature service. It features good formability, weldability, and structural stability in thermal cycling environments. With superior creep‑rupture strength compared to standard Incoloy 800, it is widely used in high‑temperature pressure parts and industrial furnace components.
