In order to understand the degrading behavior of hydrogen embrittlement of SUS 316 austenitic stainless steel weldment, base metal and welded joints which were welded with EBW and SMAW and heat-treated at 650℃-24hr for carbide and 850℃-6hr for Sigma-phase precipitation after welding were evaluated in tensile test at room temperature with and without hydrogen charging in the autoclave at 450℃-220atm-48hr treatment. As a result the drastic degrading to 40% in reduction in area of the welded joint was observed when hydrogen of 41ppm was contained in the welded joint of SUS 316 stainless steel.
