Fatigue behaviour of corrosion pits in X65 steel pipelines [PDF]

Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2018
Corrosion pits are a form of geometrical discontinuity that lead to stress and strain concentration in engineering components, resulting in crack initiation under service loading conditions and ultimately fracture and failure. Initiation and propagation of cracks in offshore pipelines can lead to loss of containment and environmental and commercial ...

The Influence of Subcritical Annealing and Cold Working on the Hydrogen Embrittlement Susceptibility of X65 D Pipeline Steel

Materials and Corrosion, Volume 76, Issue 10, Page 1478-1496, October 2025.
This study investigated the effect of subcritical heat treatment and cold work on the hydrogen embrittlement (HE) susceptibility of the X65 D pipeline steel. Hydrogen charging reduced the ductility of all specimens. Both subcritical annealing and cold working decreased somewhat the degree of HE.
