A carbide strengthened nickel-chromiumtungsten 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. Potential applications for this alloy include equipment and components for landbased gas turbines, thermal and petrochemical processing, heat treating, and ore refining.
