The demands on suspension components for their safety standards over the entire vehicle life are paramount. This requires completely trouble-free production processes in the forming of the individual parts and their subsequent assembly, including the joining operations. This report introduces a steel, which sustains most complicated deformation processes and ensures high component durability. In as-annealed delivery state, blanks of such kind of steel can be excellently formed into highly complex components using deep drawing or other modern forming techniques. As welded pipe, the steel can be formed with hydroforming processes without intermediate annealing. With a subsequent heat treatment, tensile strength levels of more than 800 MPa can be achieved. The new steel grade found its first industrial application in the integral support member of the new Mercedes-Benz E-Class. Due to the combination of high strength and ductility of the steel, the integral support member has a high capacity to absorb energy during a crash and yet remains insensitive to the occurring high operating loads.
