The hydrogen embrittlement of an AISI 304 steel containing different amounts of α′ martensite has been studied by charging the specimens with hydrogen through cathodic polarization and subsequent tensile testing. Increasing α′ martensite content was found to have a great effect on the fracture surface morphology and the cracking susceptibility.
