Abstract: In order to study the effect of cold rolling process on the formability of 19Cr2Mo1W ferritic stainless steel, the micro structure and texture evolution of this steel during cold-rolling and annealing processes were investigated by X-ray diffraction(XRD), electron back-scatter diffraction(EBSD),roughness and plastic strain ratio analytical methods. The results indicated that the amount of α and γ fiber textures in cold-rolled sheet increased with the increase of cold rolling reduction, and the stable orientation of α and γ fiber textures during cold rolling was223〈110〉and 111〈011〉component, respectively. In addition, the strength of the γ recrystallization texture became higher, when the amount of223〈110〉component increased. After annealing at 1050℃ for 1 min, the recrystallized ferritic grains in the sheet distributed uniformly with a fine grain size, the surface roughness was small and the strength of the γ fiber texture was relatively high, i.e.,the formability of the cold-rolled steel sheet was the best.

Key words: ferritic stainless steel, cold rolling, texture evolution, microstructure, formability
