A turbocompressor rotor for a turbocompressor for compressing process gas has a rotor body which makes contact with the process gas and which is produced entirely from a martensitic, non-rusting steel material which has 0.5 to 1.3% carbon and 26 to 30% chromium. A method for producing the turbocompressor rotor has the following steps: producing a casting model corresponding to the geometry of the rotor body by means of rapid technology, and producing a casting mould by means of the casting model; or producing a casting mould corresponding to the negative geometry of the rotor body by means of rapid technology; filling the casting mould with the liquid steel material so as to form a cast workpiece as the rotor body; completing the turbocompressor rotor with the rotor body. |
