The model formed by distributing the concentration of hydrogen in a wire influenced by acidic removal of scales and further calibration has been developed. It is shown that hydrogen strengthens steel, developing homogeneous and inhomogeneous solid solutions, and blocking the movement of dislocations. Besides, hydrogen causes steel to be brittle, forming micropores and microcracks. The transition from strengthening to brittleness of steel occurs with a slight change of hydrogen concentration and alloy elements. The developed electron-microscopic investigations of steels, of ferrite-pearlite class influenced by hydrogenation, brought to light the specific role of hydrogen in the formation of substructure during drawing, and further deformation by compression.
