          Introduction to Hydrogen Embrittlement Hydrogen embrittlement is a critical phenomenon in mechanical engineering, particularly affecting high-strength threaded fasteners made from steel or other metals. It occurs when hydrogen atoms diffuse into the metal lattice, leading to reduced ductility and sudden brittle failure under stress levels below the material’s yield strength.
