<p>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.</p> |
