Abstract: Objectives This study investigates the effects of asymmetric rolling on the texture evolution and ridging resistance of ferritic stainless steel (FSS) 430. Methods By integrating crystal plasticity finite element modelling with experimental methods, the mechanical behaviour, microstructural evolution, and ridging height under various differential speed ratios (DSRs=1.0, 2.5, and 4.0) were systematically analysed. Results The results demonstrated that the FSS 430 exhibits the best ridging resistance among the tested DSR conditions, accompanied by a significant reduction in ridging height. When rolled with the DSR of 2.5, deleterious texture components such as the {001} <110> and {114} <110> components are suppressed, whereas favourable orientations including the {111} <110> and {111} <112> components are enhanced. This transition facilitates the transformation of α-fibre into γ-fibre textures, thereby effectively disrupting banded texture clusters and promoting randomized grain orientation distribution. Conclusion The findings underscore that precise control of the DSR enables effective texture optimization, leading to the enhanced anti-ridging performance in the FSS 430 strips.
