A nickel-chromium-iron-molybdenum alloy with outstanding strength and oxidation resistance at temperatures to 2200°F (1200°C). Matrix stiffening provided by the molybdenum content results in high strength in a solid-solution alloy having good fabrication characteristics. Used in gas turbines, industrial furnaces, heat-treating equipment and nuclear engineering.
STANDARD PRODUCT FORMS
Sheet, strip, plate, round bar, flat bar, forging stock,
hexagon, wire and extruded section.
