Increased resistance to hydrogen embrittlement in high-strength steels composed of granular bainite

This paper presents two high-strength steels composed of granular bainite microstructure that have higher extrinsic resistance to hydrogen embrittlement (HE) than conventional tempered-martensite steel, because the granular bainite steel traps less hydrogen than tempered-martensite steel. However, t...
