Material Notes:
UDIMET® alloy 520 is a precipitation-hardenable nickel base 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. The primary application for alloy 520 is blading for aircraft and land-based gas turbines.Information Provided by Special Metals Corporation
