1) Remark: The steel 20NiCrMoS-2 is suitable for parts in the automobile and machine construction the parts are such that they are used for wear with a medium core strength, high toughness and fatigue strength (for example cog wheels,axles, shafts). It also possesses improved treatment properties The lowest temperature of use is -60 °C, the most favourable dimension range is up to 60 mm nominal dimension. As bright finished steel product, the steel is used in the shape of bars, bright, straight and in varying conditions (see DIN EN 10277 : 1999-10).
