Methods of transmission electron microscopy are used to establish the influence of preliminary surface decontamination on the microstructures of 20G2R and 30GIR steels after drawing and stamping. We explain how surface hydrogenation during decontamination by acid media leads to penetration of hydrogen into the metal and leads to an increase in long-range stress fields and formation of micropores and microcracks. We analyze the effect of the quantitative statistical characteristics of substructure evolution of steels with different contents of carbon and alloying elements. We consider possible mechanisms for hydrogen hardening of steel.
