Incoloy DS
Incoloy DS (W.Nr. 1.4862) is a silicon‑enhanced nickel‑iron‑chromium heat‑resistant alloy designed for high‑temperature furnace applications. It offers excellent oxidation resistance, carburization resistance, and structural stability at elevated temperatures. The alloy maintains good mechanical strength and formability, with outstanding resistance to “green rot” and cyclic heating environments. Cost‑effective and weldable, it is widely used for lightweight heat‑treatment components requiring long‑term durability in harsh thermal conditions.
