Material Notes:
A nickel-chromium-cobalt alloy that is precipitation hardenable and also contains a relatively high (7%) level of molybdenum for solid-solution strengthening. It has an exceptional combination of high-temperature strength, creep resistance, and ductility when welded. The alloy is especially suitable for welded sheet structures. Used in gas turbines for flame tubes and other components. Standard product forms are round, extruded section, sheet, and wire.Data provided by the manufacturer, Special Metals.
