Definitions
- the invention relates to a martensitic steel with delayed Z-phase formation, powder and a blank or a component from it.
- forged rotor disks of turbines in particular gas turbines, have hitherto been made from various forged steels.
- a steel based on NiCrMoV is used for compressor disks and a steel based on CrMoWVNbN for turbine disks.
- the application conditions and design requirements are decisive for the choice of forging material.
- the material with the highest application temperature is currently a CrMoWVNbN-based steel and a CrMoCoVB-based steel.
- Nickel materials are currently being discussed for higher operating temperatures.
- the object is achieved by an alloy according to claim 1, a powder according to claim 2 and a blank or component according to claim 3.
- the alloy according to the invention has at least (in % by weight): carbon (C): 0.16% - 0.24%, preferably 0.19% - 0.21%, silicon (Si): 0.0% - 0.08%, preferably 0.0% - 0.06%, more preferably 0.02% - 0.06%, Manganese (Mn): 0.04% - 0.16%, preferably 0.07% - 0 1.13%, chromium (Cr): 10.6% - 11.5%, preferably 11.2% - 11.5%, more preferably 11.2%, molybdenum (Mo) : 0.5% - 0.9% %, preferably 0.7%, tungsten (W) : 2.2% - 2.6%, preferably 2.3% - 2.5%, more preferably 2.45%, cobalt (Co) : 3.0% - 3.6%, preferably 3.25% - 3.40%, nickel (Ni): 0.09% - 0.19%, preferably 0.13% - 0.17%, Boron (B) :
- Remainder iron consisting in particular of these elements.
- silicon (Si) has the positive effect of making the melt more fluid and also serves as a deoxidizing agent. Another positive influence of silicon (Si) is that it increases tensile strength, yield point and resistance to scaling.
- chromium (Cr) and cobalt (Co) also play an important role. They increase oxidation resistance and increase heat resistance.
- a titanium (Ti)/nitrogen (N) ratio of 1.5 to 2 has proven advantageous.
- An advantageous embodiment is (in % by weight): carbon (C): 0.20%, silicon (Si): ⁇ 0.08%, manganese (Mn): 0.10%, chromium (Cr): 11, 2%, molybdenum (Mo) : 0.7%, tungsten (W) : 2.4%, cobalt (Co) : 3.3%, nickel (Ni) : 0.15%, boron (B) : 0, 0.05%, nitrogen (N) : 0.013%, titanium (Ti) : 0.02%, vanadium (V) : 0.20%, niobium (Nb) : 0.05%, copper (Cu) : 1.75% , aluminum (Al): 0.02%, balance iron (Fe) .
