1) Remark: Steel 34 CrNiMo 6 is suitable for high loaded parts (also heavy forged parts) of high heat-treatment sections and favorable ductility qualities in aircraft and heavy-vehicle construction and in machine engineering (e.g. propeller shafts, connecting rods, transmission shafts). Lowest application temp. -40 °C.
