Textures of hot rolled strips of low carbon steel were determined. Samples were taken at the entrance and exit of the hot finishing train and between each stand of it. The principal preferred orientation was (100)[011].{110}<110> was also found, which weakened with decreasing thickness. Obtained {200} pole figures can be accounted for by assuming (1) that the rolling texture of γ-phase was composed of two preferred orientations of {110}<112> and {112}<111> (2) that the compressive stress σ normal to the rolling plane and the tensile stress-σ parallel to the rolling direction are operative in rolling and (3) that the austenite transforms to the ferrite by a Kurdjumow-Sachs relationship where the austenite slip plane and slip direction which have large resolved shear stress are parallel to (110)_α and [11^^-1]_α respectively.
