Raymond, E L; Vandervoort, R R

The effect of high-pressure hydrogen gas on the tensile properties of welded or sensitized 316 stainless steel was studied to find out if hydrogen embrittlement occurs. Tensile tests on unnotched and notched specimens in air, 70-MPa helium, and 70-MPa hydrogen were conducted, using the air test results as baseline tensile properties. Results show that all specimens had good ductilities and were not notch-sensitive in high-pressure hydrogen. Fractographs reveal classic ductile-dimple failure in all specimens, but no evidence of hydrogen embrittlement.
