Abstract The aim of this paper is to study the effects of different initial solidification structures in Cr17 ferritic stainless steel on the evolution of grain colonies associated with ridging and to reveal the ridging difference of cold-rolled and annealed sheets. Five kinds of grain colonies of the rolled and annealing samples were investigated by using electron back-scattered diffraction (EBSD) analyses. The experimental results showed that the evolution of grain colonies depends on the initial solidification structure. The cold-rolled and annealed sample of equiaxed solidification structure has less {001}<110> grain colony but more {111}<112> grain colony in comparison with columnar solidification structure. Moreover, these two kinds of grain colonies of cold-rolled and annealed sample with initial equiaxed solidification structure show close distribution. The ridging difference of cold-rolled and annealed with different initial solidification structures is attributed to the differences of amount and distribution of {001}<110> grain colony and {111}<112> grain colony, but not related with {001}<010>, {111}<110>, {112}<110> grain colonies.
