Orientation microscopy (EBSD) is used to study structural and textural states through the thickness of pipe steel strips after a controlled thermomechanical treatment. It is shown that texture formation in the form of a selection of components (3 – 7) with a large number of versions of crystallographic orientations, arising with shear phase transformations in accordance with the orientation ratios, suggests presence within the steel structure of elements limiting the number of possible α′-phase orientations. It is proposed that these elements are special boundaries formed during hot rolling close to boundaries RSU Σ3 and Σ11 between deformed austenite grains.
