The susceptibility of precipitation hardening 13-8 Mo stainless steel to hydrogen embrittlement (HE) was measured by both post hydrogen charging tensile tests and by time to failure tests while being subjected to hydrogen charging and a static stress below the yield stress. In the former, it was found that the ductility was decreased substantially after only 30 min charging time. The strength was markedly reduced after 2 h charging time. In the delayed failure tests, it was found that a localized cold worked surface condition promoted crack formation.
