ABSTRACT:
A method of manufacturing formable as-rolled thin steel sheets having excellent ridging resistance and other properties is disclosed, which comprises rolling a low carbon steel to a given thickness without cold rolling and recrystallization annealing steps. In this rolling, at least one rolling pass is carried out within a given temperature range at high draft and high strain rate.
