A nickel-iron-chromium alloy precipitation hardened by titanium and aluminum and solid-solution strengthened by an addition of molybdenum. It was developed as a high-strength sheet alloy for use at temperatures to 1020°F (550°C). The high iron content provides good workability and also relatively high tensile ductility, especially after welding. Used for components of gas turbines.

STANDARD PRODUCT FORMS

Sheet, plate, round bar, flat bar, forging stock and wire.
