“…Turnbull et al [23] reported that addition of H 2 S and decreasing pH in entry electrolyte would increase the hydrogen entry. Tsuru et al [24] modified a DS set-up to study the mechanism of hydrogen entry into the steel during an atmospheric corrosion process and the effect of the steel passive layer and surface pH on the permeation rate.…”

“…Table 1 shows the chemical compositions, and Table 2 shows the thermal treatment and hardness. Figure 2 shows the metallurgical microstructures for the two materials: further details of the microstructures are given by Fallahmohammadi et al 23 Each sample of each material consisted of three specimens (1)(2)(3). In addition, samples of X65 steel Q&T at different degrees of plastic deformation obtained by tensile testing or cold rolling (6, 22 and 43%) were investigated.…”

Transport of atomic hydrogen in steels can be described by a complexmodel that takes into account\ud diffusion laws (Fick’s laws) and the phenomena of hydrogen capture and release by different traps.\ud Different electrochemical methods for measuring the diffusion coefficient of atomic hydrogen are\ud compared. Three metallurgical structures of low alloy 2.25Cr–1Mo steel and C–Mn microalloyed steel\ud are tested, the latter also with different degrees of plastic deformation. The test methodology that best\ud simulates hydrogen diffusion through a lattice is the partial charge/discharge method. Within the limits\ud of the ‘material–environment’ combinations selected for this research, highly reproducible values of\ud the diffusion coefficient are obtained, which decrease in the order of annealed,\ud quenched and tempered and quenched samples and also\ud decrease as the plastic deformation increases

“…In contrast, hydrogen can diffuse out of a reversible trap when sufficient energy is administered to the system. In a lattice with traps that contain hydrogen below its equilibrium amount, Fick's law no longer applies and a different differential equation has to be used to solve the transport equations, as discussed elsewhere (Mc Nabb & Foster, 1963;Turnbull, Saenz de Santa Maria, & Thomas, 1989).…”

Sulfide stress cracking of nickel-containing low-alloy steels

Low-alloy steels (LAS) are extensively used in oil and gas (O&G) production due to their good mechanical properties and low cost. Even though nickel improves mechanical properties and hardenability with low penalty on weldability, which is critical for large subsea components, nickel content cannot exceed 1-wt% when used in sour service applications. The ISO 15156-2 standard limits the nickel content in LAS on the assumption that nickel concentrations above 1-wt% negatively impact sulfide stress cracking (SSC) resistance. This restriction excludes a significant number of high-strength and high-toughness alloys, such as Ni-Cr-Mo (e.g., UNS G43200 and G43400), Ni-Mo (e.g., UNS G46200), and Ni-Cr-Mo-V grades, from sour service applications and can be used only if successfully qualified. However, the standard is based on controversial research conducted more than 40 years ago. Since then, researchers have suggested that it is the microstructure that determines SSC resistance, regardless of Ni content. This review summarizes the advantages and disadvantages of nickel-containing LAS in terms of strength, weldability, hardenability, potential weight savings, and cost reduction. Likewise, the state of knowledge on the effect of nickel on hydrogen absorption as well as SSC initiation and propagation kinetics is critically reviewed.
