For API 5L X52 steel, it has been found that C H ∗ = 4.3 × 10 6 mol / cm 3. Without hydrogen absorption, API 5L X52 is ductile and fatigue initiation occurs by formation of dislocation cells, slipping bands. The mechanism is controlled by plastic shearing strain. When hydrogen is absorbed in metals, hydrogen atoms pin dislocations.
The maximum decrease in the fracture toughness was about 49%. Capelle et al.
