Modeling the fatigue crack growth of X100 pipeline steel in gaseous hydrogen

•FCG tests performed on pipeline steel in air and high-pressure gaseous hydrogen.•Hydrogen-assisted (HA) FCG highly dependent upon hydrogen pressure.•HA FCG falls into two regimes depending upon the crack extension per cycle.•Single relationship proposed to correlate HA FCG of X100 steel. This work...
