Processing steels to achieve particular useful properties is a science as well as an art. Many of the properties of modern steels are a successful combination of empiric and scientific knowledge. Deep drawing low carbon steels have been used and improved through many decades of research and technological advance. However the micro mechanisms involved in the development of particular microstructures and properties are still under discussion. The current paper shows an integrated attempt to obtain consistent microscopical data from micromechanical simulations coupled with recrystallization and phase transformation codes. The simulations are performed in a way such that the information obtained from certain temperature, level or process is used in the next step to proceed further. The goal is not avoiding experiments but having a whole through scale and time integration for judging the validity of similar parameters and assumptions during the different processing steps. The simulations include high and low temperature deformation and recrystallization in the austenite region, phase transformation to room temperature, low temperature deformation and recrystallization in the ferrite phase region. The results are compared with experiments available in the literature.
