AB EN 1.4016 stainless steels combine good corrosion resistance with good formability and ductility. As such, their most popular applications are related to sheet forming. During re-crystallisation of Fe-Cr steels, deviations from the desired gamma-fibre (gamma fibre, ||ND) texture promote a decrease in deep drawability. Additionally, alpha-fibre (alpha fibre, ||RD) has been found to be damaging to formability. In this study, an EN 1.4016 basic material and a modified one with optimised settings as regards to chemical composition and manufacturing process, in order to improve the formability properties, are characterised. The phase diagram, microstructure, Lankford coefficients and Electron Backscatter Diffraction (EBSD) (results confirm the evolution of texture during the processing of ferritic stainless steel. Texture is analysed by the interpretation of Orientation Distribution Function (ODF), using orientation density results for each sample obtained in the processing route. The cube ({001} ) and rotated cube ({001} ) textures dominate the crystal orientation from the slab until the intermediate annealing stage. After final annealing, there is a texture evolution in both materials; the gamma-fibre component dominates the texture, which is much more intense in modified material supported by components that show good deep drawability, {554} , and good transition from hot to cold rolling, {332} . The modified composition and process material delivers a better re-crystallisation status and, therefore, the best drawability performance.
