Abstract: The invention relates to a steel and a processing method for high-strength fracture-splittable machine components that are composed of at least two fracture-splittable parts. The steel and method are characterized in that the chemical composition of the steel (expressed in percent by weight) is as follows: 0.40%?C?0.60%; 0.20%?Si?1.00%; 0.50%?Mn?1.50%; 0%?Cr?1.00%; 0%?Ni?0.50%; 0%?Mo?0.20%; 0%?Nb?0.050%; 0%?V?0.30%; 0%?Al?0.05%; 0.005%?N?0.020%, the rest being composed of iron and smelting-related impurities and residual matter.

Abstract: The invention relates to a steel and a processing method for producing machine components formed from solid stock, particularly for vehicle construction, having a primarily bainitic structure, characterized in that the chemical composition thereof has the following contents in weight percent: 0.10%?C?0.25%, 0.15%?Si?0.40%, 1.00%?Mn?1.50%, 1.00%?Cr?2.00%, 0.20%?Ni?0.40%, 0.05%?Mo?0.20%, 0.010%?Nb?0.040%, 0.05%?V?0.25%, 0.01%?Al?0.05%, 0.005%?N?0.025%, 0%?B?0.0050%, with the remainder being iron and the steel making-related accompanying elements and residual materials.
