Abstract: A steel workpiece may have an edge region and a core region. The object of specifying a steel workpiece wherein a maximum near-surface strength and nevertheless favorable surface properties are achieved, especially favorable scaling characteristics during hot rolling, is achieved in that the steel workpiece may be softer in the edge region than in the core region, and in that a sum total of alloy constituents C, Si, Mn, Cr, and N of the steel workpiece overall is greater than 1.45% by weight. And in some examples the sum total of the alloy constituents C, Si, Mn, Cr, and N of the steel workpiece is less than 4.5% by weight.

Abstract: A chassis component may include at least one first component part made from a structure-borne soundproofing composite material with a first metal layer, at least one second metal layer, and at least one damping layer. The damping layer may be positioned partly or entirely across a surface between the metal layers. In some cases, the first metal layer and the second metal layer may be thermally joined together in at least one place. In addition, a material thickness of the first metal layer is at least 0.2 mm. Moreover, the present disclosure relates to corresponding methods for producing such chassis components.
