The effect of H2S concentration and pH on the cracking resistance of AISI 410 stainless steel in 5% brine

Contribution of acoustic emission to the understanding of sulfide stress cracking of low alloy steels

“…Moreover, immersion of steel in H 2 S containing solutions leads to the formation of a rough surface [11]. In the present case, pitting initiation could be enhanced by the presence of H 2 S, as reported for martensitic stainless steel [47], or the presence of a relatively rough surface could constitute occluded cells and play the part of initiating pits in which acidic electrolyte can be retained.…”

Effect of nickel on hydrogen permeation in ferritic/pearlitic low alloy steels

“…Hydrogen atoms primarily occupy the tetrahedral interstitial sites in bcc iron at ambient temperatures (<100 C [44]) with the corresponding N l value of 5.2 10 23 sites cm À3 [9]. Equation ( 6) can be re-arranged to give Equation (7). If D eff is measured at several temperatures, a plot of the left hand side value of Equation ( 7) against the inverse of the temperature should fit to a straight line with a slope a and an intercept b, from which the values of N r and E b are found [32].…”

Effect of Nickel on the Hydrogen Stress Cracking Resistance of Ferritic/Pearlitic Low Alloy Steels

“…Saenz De Santa Maria and Turnbull 65 found that the SSRT performance of a martensitic stainless steel decreased with increasing values of Jss L, obtained by varying the hydrogen charging conditions. This illustrates the now well-established understanding of decreasing HSC/SSC resistance with increasing hydrogen content for a given material.…”
