Hydrogen embrittlement of a 2205 DSS has been evaluated by in-situ tensile tests at high-pressure hydrogen gas. Mechanical tests
were conducted in smooth and notched samples, following the ASTM G142 standard. Hydrogen embrittlement susceptibility was
studied at 70 and 140 bar. In the smooth samples, the loss of ductility was marked. However, the increase in hydrogen pressure
from 70 to 140 bar seems to be practically negligible. On the other hand, in the notched samples, hydrogen damage was especially
remarkable at 140 bar. Finally, hydrogen embrittlement susceptibility is also discussed based on the fracture micromechanims.
The authors would like to thank the Spanish Government for the financial support received to perform the research projects PID2021-124768OB-C21 and TED2021-130413B-I00–HyDuplex3D. This work was also supported by the Regional Government of Castilla y León (Junta de Castilla y León) and by the Ministry of Science and Innovation MICIN and the European Union Next Generation EU/PRTR (MR4W.P2 and MR5W.P3).
