1) Remark: Steel 25CrMo4 is suitable for components with high strength and toughness requirements at mean and higher heat-treatment cross-sections in vehicle, engine and machine engineering (e.g. crankshafts, steering knuckles, pinions). Lowest working temperature -40 °C Further application for mounting elements at increased and lower temperatures.
