DIN 17440: X6CrMoS17 Soft-Annealed Steel (Grade +A) – Industrial Specification

The steel 20 Cr 4 is used for high wear loaded parts in the vehicle and mechanical engineering (e.g. camshafts, piston pins, cylinder). The lowest application amounts to -25 °C, the best application up to 25 mm nominal size.PropertiesGeneralPropertyTemperatureValueDensity20.0 °C7.83 - 7.85 g/cm³Mech

The steel 20 MoCrS 4 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.

The steel 16 MnCr 5 is used for larger parts with higher core strength and advantageous toughness properties in the vehicle and mechanical engineering (e.g. gears, shafts, steering parts). The lowest application amounts to -25 °C, the best application up to 50 mm nominal size.PropertiesGeneralProper
