The alloy is nickel-based. Chromium imparts resistance to high temperature corrosion. Oxidation is further enhanced by a micro-addition of 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 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.
