Using the Fourier analysis method, we studied the anisotropy of the Young's modulus (E) in the crystallographic planes of the main ideal orientations (IO) of the textures in α-iron sheets. The dependences of E on the direction of measurement, the anisotropy coefficients and the average values of E for the various IOs of annealing and rolling textures in α-iron are obtained. The texture of low-carbon DC04 (0.06 % C, up to 0.35 % Mn, up to 0.40 % Si, ~ 0.025 % S and P) steel sheets after annealing and cold rolling was investigated. The IO set of annealed sheets provides anisotropy of E with a maximum in the transverse direction (TD) and a minimum in the rolling direction (RD) + 45°. The process of rolling forms IOs which increase the Young's modulus in the TD and RD + 45°. The experimental values of E are in satisfactory agreement with the results of the calculations from the anisotropy of the IO obtained from an X-ray texture experiment.
