Nimonic 90 is a precipitation-hardenable nickel-chromium-cobalt alloy having high stress-rupture strength and creep resistance at temperatures to about 1700°F (920°C). Nimonic 90 also has good resistance to high-temperature corrosion and oxidation. Nimonic 90 is used for blades and discs in gas turbines, hot-working tools, and springs.
Available forms of Nimonic 90 are round, flats, extruded section, plate, sheet, strip, tube, and wire.
