Product Description

A precipitation-hardenable nickel-chromiumcobalt alloy with an addition of molybdenum for solid-solution strengthening. It has high strength and corrosion resistance along with good formability and high-temperature ductility in welded structures. The alloy is especially suitable for sheet applications. Used in gas turbines for rings, casings and various sheet fabrications.
STANDARD PRODUCT FORMS
Sheet, strip, plate, round bar, flat bar, forging stock, wire and extruded section.
