New cold rolled, deep drawing steel qualities

Ziel

High strength cold rolled steels offer the possibility of considerable weight reduction in the automotive industry if formability can be improved compared to conventional grades. Four promising steel concepts will be developed in this project:
- in multi-phase (TRIP) steels TRansformation Induced Plasticity will retard local necking and thus improve formability;
- SULC Steels with extreme low C and N levels are bake hardenable steels without the drawbacks of conventional IF (Ti, Nb) grades;
- high strength IF steels (IFHS) are potentially capable of developing optimum combinations of formability and strength by using solid solution and bake hardening;
- IF steels (IF-D) doped with surface active elements, will develop the most favourable deep drawing textures.
Generally it is intended to develop new cold rolled steels with strength levels between about 200 and 600 Mpa with improved formability compared to existing grades. This will improve the position of steel compared to alternative materials, and promote more efficient use of high strength steels.
