Abstract
A method is proposed for determining the effect of an aggressive hydrogen-containing medium on the tensile strength of steel. For this, an experiment was carried out on the tension of a 09G2S steel specimen after hydrogenation. Since the processes of heat transfer and diffusion of hydrogen in a metal have different physical times, but are described by equations that are identical in structure, the study uses a well-developed mathematical apparatus for solving heat conduction problems to solve the problem of hydrogen diffusion into the metal. The results of experimental and numerical studies of the cylindrical part of the specimen allow us to obtain an equation describing the change in the breaking strength for the steel depending on the concentration of hydrogen in it.
