Tensile and fatigue tests were performed on 304 stainless. Samples were exposed to high pressure hydrogen (138 MPa) or 1 atm hydrogen or were unexposed. Tensile tests were performed at displacement rates ranging between 3.81 mm min-1 to 0.05 mm min-1. Tensile results preliminarily indicate that there is a displacement rate effect. The effect of supersaturation hydrogen exposure is to decrease the tensile failure stress to approximately half that of the unexposed sample failure stress. Bending fatigue samples show a marked decrease in fatigue life from supersaturation hydrogen exposure.
