UDIMET® alloy 188

A cobalt-base alloy with excellent high temperature strength and good oxidation resistance to 2000°F (1093°C). The high chromium level coupled with small additions of lanthanum produce an extremely tenacious and protective scale. The alloy also has good sulfidation resistance and excellent metallurgical stability displayed by its good ductility after prolonged exposure to elevated temperatures. Good fabricability and weldability combine to make the alloy useful in typical gas turbine applications such as combustors, flame holders, liners and transition ducts.

UDIMET® alloy L-605

A cobalt-base superalloy with good formability, high strength to 1500°F (816°C), and good oxidation resistance to 2000°F (1093°C). The alloy also has good sulfidation resistance and resistance to wear and galling. The alloy is used in the hot sections of aircraft and land based gas turbines in combustor liners and other applications requiring moderate strength and good oxidation resistance at high temperatures. The alloy can also be used in industrial furnace applications such as muffles/liners in high temperature kilns.

UDIMET® alloy 520

A precipitation hardenable nickel superalloy with an exceptional combination of high temperature mechanical properties, corrosion resistance and forgeability characteristics. Developed for use in the 1400–1700°F (760–927°C) temperature range, the alloy has excellent structural stability and unusually good fabricability. Primary application is blading for aircraft and land-based gas turbines.

UDIMET® alloy 720

A nickel alloy solid solution strengthened with tungsten and molybdenum and precipitation hardened with titanium and aluminum. The alloy combines high strength with metallurgical stability as demonstrated by excellent impact strength retention after long exposures at elevated temperatures. Good oxidation and corrosion resistance combined with high strength make the alloy useful in gas turbine blade and disc applications.

UDIMET® alloy D-979

An iron-nickel alloy designed for turbine disc applications at temperatures up to 1200–1400°F (649–760°C). Hardened by a complex precipitation of intermetallic phases, the alloy combines corrosion resistance with excellent tensile and stress rupture strength.

UDIMET® alloy R41

A precipitation hardenable nickel-chromium alloy containing significant amounts of cobalt and molybdenum along with lesser amounts aluminum and titanium that exhibits extremely high room and elevated temperature mechanical properties. Excellent corrosion resistance and fabricability have led to wide usage in critical aircraft engine components such as nozzle partitions, turbine blades and wheels, combustion chamber liners and structural hardware.

UDIMAR® alloy 250

An age hardenable (maraging) iron-nickel steel combining ultra-high strength, Toughness and resistance to crack propagation. The alloy is well suited to applications where heat treatment distortion and dimensional changes must be minimized and where high Fracture Toughness is required, such as rocket motor casings, light aircraft landing gear, power shafts and low temperature tooling.

 

 UDIMAR® alloy 300

An age hardenable (maraging) iron-nickel steel combining ultra-high strength and resistance to crack propagation. The alloy is well suited to applications where heat treatment distortion and dimensional changes must be minimized and where high Fracture Toughness is required, such as rocket motor casings, light aircraft landing gear, power shafts and low temperature tooling.
