Abstract

Aimed at the retention of steel in the car body, steel producers, including ArcelorMittal, are developing ultra high strength steels with tensile strength above 1000 MPa to facilitate weight reduction of critical safety parts while ensuring crash worthiness (high absorbed energy) and high anti-intrusion resistance. In conjunction with ultra high strength, such steels are being designed for high formability including not only high elongation, but also high bendability and high hole expansion. New developments include TRIP (TRansformation Induced Plasticity) assisted dual phase steels, carbide free bainitic steels, medium Mn steels, Q&P (Quenching and Partitioning) steels and fully martensitic steels. This presentation, based on laboratory results of AM as well as on literature review, covers key features
