We propose a theoretical and experimental approach to the quantitative evaluation of the influence of hydrogen on the mechanical properties of 40Kh steel. We experimentally determine the characteristics of strength and plasticity and construct analytic dependences of the yield strength, true fracture stresses, and relative narrowing of 40Kh steel on the concentration of hydrogen in steel.
