Which consequence results when high hydrogen partial pressure degrades steel?

💡 Explanation

Hydrogen embrittlement weakens steel because hydrogen atoms diffuse into the metal lattice, causing **decohesion** along grain boundaries; therefore, the fracture toughness decreases rather than increases. This effect accelerates cracking under mechanical stress, rather than improving yielding or oxidation resistance.
