By focusing on non-diffusible hydrogen causing hydrogen embrittlement in austenite base stainless steel, it is intended to provide austenite base stainless steel free from the non-diffusible hydrogen by heating austenite base stainless steel at a heating temperature of 200 to 500oC for not longer than 460 hours while maintaining it in an evacuated atmosphere of 0.2 Pa or less to thereby eliminate hydrogen (H) contained in the austenite base stainless steel to 0.00007% by mass (0.7 ppm by mass) or less.
En se concentrant sur l'hydrogène non diffusible provoquant une fragilisation par l'hydrogène d'un acier inoxydable austénitique, on vise à proposer un acier inoxydable austénitique exempt d'hydrogène non diffusible par chauffage de l'acier inoxydable austénitique à une température de chauffage de 200 à 500°C pendant au plus 460 heures tout en le maintenant dans une atmosphère sous vide de 0,2 Pa ou moins, ce qui permet de diminuer la quantité d'hydrogène (H) contenue dans l'acier inoxydable austénitique jusqu'à 0,00007 % en masse (0,7 ppm en masse) ou moins.
