Description

MP35N™ is a nickel-cobalt alloy which provides a unique combination of properties including ultra high strength, toughness, ductility, and outstanding corrosion resistance. MP35N™ is produced by vacuum induction melting followed by VAC-ARC remelting to provide exceptional control of chemistry and ingot solidification. MP35N™ has a face centred cubic structure matrix of cobalt and nickel, in which chromium and molybdenum are soluble at elevated temperatures. The FCC structure persists upon cooling to room temperature and below. The combination of the amount of cold work and ageing temperature achieves the final properties desired. For AMS 5844/5 (fully strength/heavily cold worked) material, the alloy is typically aged at 1050ºF for 4 hours.
