Abstract: The Cr17 ferritic stainless steel specimens of different initial microstructures were produced by thin strip casting and investigated comparatively for their texture evolution via the same cold rolling and annealing processes. The results showed that the texture evolution closely relates to the initial microstructure and texture of the cast strips. The cast strip with columnar crystals presents clearly the <001>//ND fiber texture, while the cast strip with equiaxed crystals presents the weak and nearly random texture. Then, after cold rolling, the mild α-fiber texture and homogeneous γ-fiber texture form in both the two types of cast strips, among which the latter shows much stronger α-fiber and γ-fiber textures than the former. After the recrystallization annealing, both the two types of cast strips form the homogeneous γ-fiber recrystallization texture which is clearly stronger in the latter than in the former.
