Definitions

the following relates to a martensitic steel having delayed Z-phase formation and a component made of this.
forged rotor disks As a function of the use condition, forged rotor disks have hitherto been produced from various forging steels. Thus, a steel based on NiCrMoV is used for compressor disks and a steel based on CrMoWVNbN is used for turbine disks.
the use conditions and the design requirements are decisive for the selection of the forging material.
the material having the highest use temperature is at present a steel based on CrMoWVNbN and a steel based on CrMoCoVB. Both materials are unsuitable in the 800-900 MPa strength class for use above 773K and 823K, respectively.
An aspect relates to solving the abovementioned problem.
the alloy composition of martensitic steels has hitherto been restricted by the formation of the Z-phase.
the following relates to an alloy which comprises at least (in % by weight):
the inventive step lies in the development and validation of new Z-phase-delaying alloys for primary use as rotor disk in gas turbines.
use temperature can be increased and therefore makes power and performance increases for the machine possible without external cooling being necessary.
