Abstract The through-thickness texture evolution and formation mechanism of γ–fiber recrystallization texture in ultra–low C, N 17%Cr ferritic stainless steel during warm rolling were investigated. The results show that: 1.The texture of the cold rolled and annealed sheet displayed pronounced throughthickness texture gradients that were inherited from the hot rolling texture gradients due to the variation of strong through-thickness strain states during warm rolling; 2. After hot rolling and annealing the surface texture consists of a strong shear texture, and the textures with major components at {112}<110>and {111}<110> can be obtained after cold rolling. Therefore, the inhomogeneous γ–fiber recrystallization texture was formed after cold rolling and annealing; 3. The γ–fiber is the major component after the hot
rolling and annealing at mid–section and 1/4–section, and after cold rolling γ–fiber with major component at {111}<112> and the intensity close to that of α–fiber can be obtained. Therefore, a uniform γ–fiber recrystallization texture was formed after cold rolling and annealing.
