| 1) Remark: Steel 25CrMoS4 is suitable for high loaded parts (also heavy forged parts) of high heat-treatment sections as well as favorable ductility qualities in aircraft, heavy vehicle and machine engineering (e.g. propellershafts, connecting rods, transmission shafts). As a bright steel product it is used in the form of bars, bright, straight, in various conditions (see DIN EN 10277 : 1999-10). |
