EN 10269 Grade 42CrMo4 treated for cold shearing (+S)
EN 10269 Grade 42CrMo4 treated for cold shearing (+S) introduction
Steel 42CrMo4 is suitable for high-stress components (also large forged parts) in vehicle, engine and machine engineering with high wear resistance and very favorable core properties ( e.g. crankshafts, pinions, balance shafts). The steel shows a high resistivity to static and dynamic loading.
Lowest working temperature -40 °C
Further application for mounting elements at increased and lower temperatures.
