AB Ferritic stainless steel (FSS) is widely used to manufacture deep-drawn products forcorrosion resistance applications, being the alloy drawability strongly affected by its microstructuralanisotropy. This study combines a variety of microscopy techniques enabling in-depth analyses of themicrostructural evolution of two different FSSs correlated to their deep drawing performance. One ofthe steels has a good correspondence with the standard EN-1.4016 (AISI 430). The other is a modifiedversion of the previous one with higher contents of the ferrite-stabilising elements Si and Cr, andlower contents of the austenite-stabilising elements C, N, and Mn. Electron Backscatter Diffractionresults confirm that the microstructural properties and drawability of FSS in the deep drawingprocess are improved in the modified steel version. Scanning transmission electron microscopy underlow-angle annular dark field conditions evidences that the deformation mechanism of FSS duringdeep drawing follows a microstructural distortion model based on the grain size gradient and showsa variation of the deformation texture depending on the alloy composition. This work demonstratesthe potential of advanced microscopy techniques for optimising the processing and design of ferriticstainless steels, with slight variations in the alloy composition, for deep drawing applications.
