Experimental and numerical investigations of the surface roughening (namely, ridging or roping) in ferritic stainless steels were presented in this paper. Stainless steels exhibiting distinct level of ridging were selected as samples; i. e., MatA: severe ridging, MatR: low ridging. The roughness of the uniaxially elongated specimens up to 15% in rolling direction was measured and predicted using rate-dependent crystal plasticity FEM. For the input of the material model, initial textures of the two materials on the 5 sequential RD planes which were obtained by mechanical polishing in identical abrasive depth were measured by EBSD (Electron back-scatter diffraction). Measured respective 2-D textures were collected and mapped onto the FE mesh in each material. Ridging profiles by CPFEM using both 1-layer and 5-layer texture were compared to the experimental results. Predicted ridging profile of MatR by 3-dimensional, i.e. using 5-layer EBSD, orientations was in good agreement with experiment. On the other hand, 2-dimensional approach was sufficient to estimate the ridging in MatA.
