Thanks to the introduction of UHSS (Ultra-High Strength Steels) and a consequent design, Fiat Auto can reach significant weight reduction (requested by the new emissions requirements) and an increased crash resistance (increased attention of the customers for Euro-NCAP evaluations). The use of UHSS steels has increased in the recent Fiat Auto car models. In this paper, the main characteristics of such steels are presented. Fiat Auto has been cooperating with the steel mills and the steel component suppliers. Their resident engineers have chosen the materials with Technical Direction, in order to avoid some problems that caused the failure of these steels in the past projects. Furthermore, the increased technical information given by Fiat Materials Engineering and the steel mills, allowed Fiat Technical Direction to build a reliable virtual model. This paper describes the work done till today and the efforts in order to introduce more UHSS steels in car models, facing the increased spring back problem. Some examples are given explaining the importance of the involvement from the beginning of the suppliers that before were not part of the decision process.
