Orientation distribution in the 17%Cr stainless steel rough rolled with inter-pass time of 10s (specimen A) and 30s (specimen B) respectively were investigated utilizing SEM-ECP (selected area electron channeling pattern).<BR>Large colonies, groups of grains with the same orientation, of {100} <011>orientation are found in the specimen A after rough rolling. It is proposed to be formed by the poor static recrystallization during rough rolling due to the short inter-pass time and the suppression effect of static recrystallization caused by the &alpha;-&gamma; transformations immediately after the final pass of the rough rolling.<BR>Large ridging is observed in the cold rolled and annealed specimen A.<BR>The cause of the large ridging is considered to be due to the large colonies of {100} <011> orientation inherited from the rough rolled stage and scattered asymmetrically along the central line of the specimen thickness.
