Development of new DDQ grade combining low ageing sensitivity, BH and higher n-value

Objective

In the production process of exposed car panels, cold rolled sheets are deformed and submitted to a paint baking process. To obtain the required final stamped steel sheet, several steel properties must be developed and controlled for deep-drawing such as high n-value, low ageing sensitivity and Bake hardening. In order to obtain a better understanding of the involved mechanisms, correlation will be searched between these three properties, the process parameters (coiling temperature, annealing temperature) and metallurgical characteristics such as precipitation density and distribution, solute carbon distribution and dislocation density. Two types of steel grades will be investigated, Nb and/or Ti sub-stoechiometric ULC steel grades.
