Definitions

  • the invention relates to a martensitic steel with a Z phase and a component thereof.
  • forged rotor disks In correlation with the application conditions, forged rotor disks have so far been made from different forged steels.
  • a steel based on NiCrMoV is used for compressor disks and a steel based on CrMoWVNbN is used for the turbine disks.
  • the application conditions and design requirements are decisive for the choice of forging material.
  • the material with the highest operating temperature is currently a steel based on CrMoWVNbN and a steel based on CrMoCoVB. Both materials are not suitable for use above 773K or 823K in the 800-900MPa strength class.
  • Nickel materials are currently being discussed for higher operating temperatures. Nevertheless, current research suggests that iron alloys can be used up to 873K.
  • the alloy according to the invention has at least in% by weight: Carbon (C): 0.15% - 0.25%, preferably 0.19% - 0.21%, Silicon (Si): 0.0% - 0.08%, preferably 0.0% - 0.06%, Manganese (Mn): 0.03% - 0.20%, preferably 0.05% - 0.15%, Chromium (Cr): 9.5% - 10.5%, preferably 9.8% - 10.2%, Molybdenum (Mo): 0.4% - 1.0%, preferably 0.6% - 0.8%, Tungsten (W): 1.6% - 2.4%, preferably 1.9% - 2.1%, Cobalt (Co): 2.5% - 3.5%, preferably 2.8% - 3.2%, Nickel (Ni): 0.0% - 0.40%, preferably 0.0% - 0.20%, Boron (B): 0.003% - 0.02%, preferably 0.006% - 0.01%, Nitrogen (N): 0.0% - 0.40%, preferably 0.
