[en] The effect of nature of group 1 and 3 cations on the critical stress intensity factor K_HE of high-strength steels, which characterizes quantitatively hydrogen embrittlement during corrosion cracking, is investigated. Experiments were carried out at room temperature using samples of 02N18K9M5T maraging steel 210x25x2 mm (σ_f=2100 MPa, HRC 55) with a lateral fatigue crack in case of axial stretching in a device permitting to follow the crack development continuously by measuring electric resistance. The test results obtained for 02N18K9M5T steel were compared with the ones obtained for martensitic steels 38Kh (0-3)NMFA (σ_b=1600....1700 MPa, HRC 48... 51). A decrease in the tendency of high-strength steels to hydrogen embrittlement (increase in K_HE) in solutions with a constant anion composition with the charge increase and with radius decrease in group 1-3 cations is detected. The effect of cation nature on K_HE is detected in solutions with pH 1.1... 14. The effect is particularly pronounced for anions OH^-, NO₃^-, CrO₄^2- as compared with anions Cl^-, Br^-, SO₄^2-, ClO₄^-
