We study the crystallographic textures and microstructures in longitudinal and cross sections of circular hot-rolled rods made of 25G2S and St3kp reinforcing steels. The distribution of orientations of the crystal is specific. It is described as a double “cylindrical” axial texture with 〈100〉 and 〈110〉 directions parallel to the axis of the rods. The anisotropy of elongation of grains is insignificant. We discuss the mechanisms of formation of the crystallographic texture responsible for the anisotropy of electrochemical corrosion of hot-rolled rods with circular cross sections made of steels with low contents of carbon. In steel rods with medium and high contents of carbon, the anisotropy of electrochemical corrosion is caused by the structural texture.
