Austenitic stainless steel and its hydrogenation method |
| abstract |
The austenitic stainless steel and the hydrogenation method of the present invention are intended to suppress the occurrence of fatigue cracks and the development of fatigue cracks by occupying hydrogen in the austenitic stainless steels. In particular, paying attention to the amount of diffusive hydrogen and non-diffusible hydrogen which are the cause of hydrogen embrittlement of austenitic stainless steel, the amount of diffusible hydrogen and non-diffusible hydrogen contained in the austenitic stainless steel is 0.0030 mass% (30 mass). ppm) or more to improve the fatigue strength characteristics of the austenitic stainless steel. Austenitic stainless steels are heat treated at a heating temperature of 200 to 500 ° C. for up to 460 hours in a hydrogen environment. Therefore, hydrogen (H) contained in austenitic stainless steel is made into 0.0030 mass% (30 mass ppm) or more. |
