INCONEL® alloy N06230 (UNS N06230 / W.Nr. 2.4733) is a carbide strengthened nickel-chromium-tungsten-molybdenum alloy with an exceptional combination of strength, stability, and resistance to corrosion at very high temperatures. Alloy N06230 offers particularly good resistance to oxidation at temperatures greater than 1800°F (980°C). It also offers good resistance to carburization and nitridation.

The alloy is nickel-base. Chromium imparts resistance to high temperature corrosion. Oxidation is further enhanced by a micro-addition of the rare earth element, lanthanum. Tungsten and molybdenum in conjunction with the alloy's high carbon content are largely responsible for the strength of the alloy. The creep resistance of alloy N06230 is optimized by control of the boron content.

The combination of high temperature strength and resistance to creep, stress rupture, and corrosion make the alloy attractive for service at temperatures above 1800°F (980°C). Potential applications include equipment and components for land-based gas turbines, thermal and petrochemical processing, heat treating, and ore and metal refining.
