hydrogen in the ferrite- pearlite pipeline steel leads to irreversible changes in the material’s microstructure, increasing its defectiveness and, consequently, affects on the macroscopic mechanical behaviour of steel. The formal description of the received unobvious experimental observations is done and the corresponding evidence was presented. For a detailed explanation of these phenomena and the mechanisms of their realization, further special multidisciplinary studies are required. The obtained results may be useful for the development of new models of hydrogen effect on the engineering metallic materials and will promote to review the existed conceptions where the hydrogen is considered as the exclusively negative agent. These results also might be applicable under the modification of the technology for processing of this class steels for the optimization of their service characteristics.
