Possibilities and challenges using advanced high strength steel sheets for automomotive applications

Applications of high strength steels in automotive parts and components are already implemented. Nevertheless, new advanced high strength steels continue to be investigated and developed. An understanding about these steels as well as the implementation has become more and more important. In order to fulfill the CO2 commitment and meet high customer satisfaction, the car manufacturers have to reduce weight and cost while simultaneously improving crash performance and quality. To use these materials, there are many challenges to overcome, e.g., springback compensation and adaptation of simulation tools. Optimized product development and a flawless production process beginning with forming followed by joining and painting are and will be a challenge. Using advanced high strength steels leads to improved products by the improvement of comfort, design, fuel consumption, safety and driving quality. These improvements may be achieved with at no cost increase or just slightly increased costs. The right combination of all material grades and the optimized application will lead to the overall goal of an outstanding and exciting product. (AU)
