Abstract The behaviour of hydrogen induced cracking of three low carbon alloysteels, 15Mn, 15MnVB and 20MnVB, has been studied in the aqueous solution of 0.1N HCl. Three different structures ,of them: bainite, tempered martensite and F/M dual-phase revealed after heat treatment. Using the data of the delayed failure and fracture mechanics tests, the σ_n/σ_(bn) vs t_f and da/dt vs K were plotted. The experimental results showed that the best susceptibility to hydrogen embrittlement resistance is the structure of isothermal bainite, the worst one is of tempered martensite and F/M duai-phase structure is obviously reduced the hydrogen induced cracking tendency.
