DIN 1652-3 Grade 22CrMoS3-5: Ferritic‑Pearlite Heat Treatment & Cold‑Drawing for High‑Performance Automotive Components
The steel 22 CrMoS 3 5 is used for wear loaded parts in the vehicle and mechanical engineering with medium core strength, better machinability, high toughness and high fatigue strength (e.g. gears, shafts, axles). The lowest application amounts to -60 °C, the best application up to 60 mm nominal size.
