Effect of microalloying on hydrogen embrittlement resistance of 125ksi grade petroleum pipe
In this study, the influence of incorporating equimolar proportions of vanadium, titanium, and niobium microalloying elements into C110 steel on the hydrogen embrittlement susceptibility of oil casing steel was investigated at a strength level of 125 ksi. Experimental analyses including microstructu...

| description | In this study, the influence of incorporating equimolar proportions of vanadium, titanium, and niobium microalloying elements into C110 steel on the hydrogen embrittlement susceptibility of oil casing steel was investigated at a strength level of 125 ksi. Experimental analyses including microstructural assessment and hydrogen permeation testing were performed to examine the impact of vanadium, titanium, and niobium microalloying elements on the stress-sustained rupture testing (SSRT) hydrogen embrittlement fracture behavior of the steel. It was demonstrated that the incorporation of vanadium microalloying elements at equimolar proportions predominantly enhances the presence of irreversible hydrogen trapping sites, enhances the resistance to tempering softening, and ultimately augments the hydrogen embrittlement resistance of the material. |
