SLIMulations mit ahss classic

ahss classic dual-phase and complex-phase steels are the proven, high-strength solution for a wide range of applications. In the SLIMulations, original steels were compared with possible ahss classic steels based on specific components. Corresponding crash tests were simulated. The baseline represents a 5-star-safety mid-size car (source: NCAP).
