Material Notes:
A precipitation-hardenable nickel-chromium-cobalt alloy having high stress-rupture strength and creep resistance at temperatures to about 1700°F (920°C). The alloy also has good resistance to high-temperature corrosion and oxidation. Used for blades and discs in gas turbines, hot-working tools, and springs. Standard product forms are round, flats, extruded section, plate, sheet, strip, tube, and wire.Data provided by the manufacturer, Special Metals.
