1) Remark: Steel 34CrMo4 is suitable for parts with high strength and toughness requirements at mean and higher heat-treatment sections (also large forged parts) in vehicle manufacturing, engine and machine engineering (e.g. shafts, gear wheels, steering knuckles). The steel shows high resistivity to static and dynamic loading. Lowest working temperature -20 °C.
