This study presents a novel in situ methodology combining potentiostatic electrochemical charging and mechanical testing to investigate HE in vintage API 5 L X52 pipeline steel. The effects of electrolyte acidity, applied potential, and hydrogen recombination suppression were systematically explored and related to the absorption of ∼1 ppm of hydrogen simulating the critical operating condition in pipelines. This led to a sharp drop in ductility and transition to mixed-mode fracture with a brittle fracture evolving radially in the outer layer and progressing to a ductile core. Additionally, the role of MnS inclusions was confirmed not only as crack initiators but also as crack propagators, even under moderate hydrogen levels.

The corrosion kinetics of nickel Alloy 270 (pure nickel) was also assessed for reference. To evaluate the kinetics of metal dissolution under aggressive conditions, downward potential scans were performed on one-dimensional (1D) pit samples. These scans were used to determine the dissolution current density across a range of temperatures at a fixed metal cation concentration at the metal surface corresponding to the saturation level at 20 °C (C<sub>sat_20</sub>). Repassivation behavior was evaluated using constant potential and constant temperature tests. In the first approach, downward potential scans at 25 °C were employed to identify the potential and pit depth at which repassivation occurs for each alloy. In the second method, downward temperature scans under constant applied potential were used to assess the corresponding temperature and pit depth at repassivation. Under charge-transfer-controlled conditions, pure nickel exhibits the slowest dissolution kinetics, followed by Alloy 600, with SS304 exhibiting the fastest rate. However, SS304 demonstrates a greater tendency to repassivate compared to Alloy 600. The critical concentration for repassivation was 60 % of the saturation concentration for SS304 and 15 % for Alloy 600.

Fatigue crack growth (FCG) tests revealed that adding 991 vol ppm water vapor to a hydrogen environment markedly suppressed hydrogen-induced acceleration in the SCM435 steel. The crack growth rate in moist hydrogen was reduced by approximately 8 times compared to dry hydrogen for both strength levels, reaching levels comparable to those in air. Scanning electron microscopy analysis indicated that fracture surfaces in the moist hydrogen exhibited ductile transgranular fracture, contrasting with the quasi-cleavage and intergranular fracture features observed in dry hydrogen, confirming the protective effect of water vapor.

Increasing water coverage raised the hydrogen dissociation barrier from 0 to 0.39 eV, reducing the dissociation rate constant by over 10⁷.
