Abstract
The tensile properties of Types 304L and 310 austenitic stainless steels have been studied at 20 and 150 C (68 and 302 F) after cathodically charging with hydrogen at 100 C (212 F). The charging conditions were such as to avoid the complicating effects of hydrogen induced phase changes and surface cracking. It was found that a substantial decrease in ductility and flow stress was produced by the dissolved hydrogen. The implications of these results relative to the current controversy concerning the role of hydrogen in stress corrosion cracking (SCC) in the alloys is examined.Keywords
