A structural chassis or body part, in particular axle support, includes at least two steel components having different strengths, with one of the components being heat-treated. The components have different strengths, whereby the heat-treated component can have a yield strength of about 900 MPa. The components may each be made of separate parts, with the separate parts as well as the components themselves being joined together, for example by welding.
