The threshold diffusible hydrogen contents of steel SM90, SM95 and C90 for hydogen blistering are 1 .76, 4.3, and 8.38×10-6, respectively, and the total hydrogen contents 4.24, 6.35 and 10.22 × 10-6 respectively. The threshold stresses of hydrogen-induced fracture corresponding to SM90, SM95 and C90 in NACE solution are σ_(th) /σ_s = 0.64, 0.80 and 0.85, respectively. The threshold stress intensity of hydrogen- induced fracture for C90 decreases with the increase in the diffusible hydrogen content w_o and the experimental result which is consistant with theoretical analysis is as follows: K_(IH) = 46- 1 2. 5lnw_0.
