Hydrogen embrittlement is the process by which various metals, most importantly high-strength steel, become brittle and fracture following exposure to hydrogen.

Hydrogen embrittlement is also known as hydrogen induced cracking or hydrogen attack. Materials that are most vulnerable include high-strength steels.

Since it was realised many years ago that increasing strength levels tend to decrease the resistance of steels to hydrogen embrittlement [2], [3], the work carried Cited by: Mechanisms of hydrogen embrittlement in steels and other materials are described, and the evidence supporting various hypotheses, such as those based on hydride.
