This research work focused on the manufacture of profiled stainless steel structures for use in automobile bodies. Lightweight components based on tailor rolled blanks can be made which was shown by the manufacture of model components for the automotive industry. These components were not only lighter in weight by 13% compared with structures of a conventional initial material, but also showed a significantly improved structural behavior in static and dynamic load tests. The process chain started with a flexible rolling process followed by an air bending step to manufacture semi-finished profile components jointed to closed profiles by laser welding. At the endof the process, the final rounding took place to desired target radii using an adapted three-roll bending process. The individual manufacturing steps and their integration within the process chain have been optimised by experimental studies and finite element analysis. New perspectives for the use of steel as the material for load-adapted and weight-optimized structure elements and sheet metal parts were opened up. Further research work will have to be carried out to increase the process reliability and to optimize the process efficiency.
