Material Notes:
UDIMET® alloy 720 is a nickel base 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.Information Provided by Special Metals Corporation
