Which outcome occurs when hydrogen embrittlement affects a high-strength steel pipeline carrying natural gas?

💡 Explanation

When hydrogen embrittlement occurs, hydrogen atoms diffuse into the steel lattice, reducing its cohesive strength because the hydrogen interacts with the microstructure and promotes crack initiation. Therefore, pipeline cracking occurs under sustained stress, rather than increased ductility, oxide layer formation, or improved fatigue resistance, which require different material modification mechanisms.
