The shipbuilding industry is increasingly exploring new technologies for the transportation and storage of liquid hydrogen (LH2) to support the transition to a sustainable green economy. Ensuring structural safety in LH2 storage tanks is critical due to the extreme storage conditions (−253 ℃ at 1 atm), where the selection of appropriate materials is of paramount importance. For LH2 membrane-type tanks, corrugated austenitic stainless-steel sheets are considered among the candidate materials for constructing the primary barrier due to their excellent mechanical properties at cryogenic temperatures, high resistance to hydrogen penetration, and superior weldability. However, the pre-deformation of the steel caused by corrugation favors strain-induced martensitic transformation, which may reduce resistance to hydrogen embrittlement (HE). Understanding and controlling this transformation is essential for maintaining structural integrity. The combined effect of pre-deformation and hydrogen environment remains unclear; therefore, this work aims to provide insights into the interaction of these factors. AISI 316L was chosen as the material for this study and was subjected to various levels of uniaxial pre-strain (10%, 20%, and 30%) to simulate the different pre-deformation levels of corrugation. Metallographic analysis via Electron Backscatter Diffraction (EBSD) provided invaluable insights into the phase transformations induced by pre-deformation. Cathodic charging was used to introduce hydrogen into tensile specimens, and the effect of hydrogen (H) was evaluated through the study of fracture surfaces. It is anticipated that the experimental findings will enhance the understanding of phase transformations influencing hydrogen embrittlement (HE) in austenitic stainless steels exposed to LH2, ultimately guiding the development of structures with tailored properties for LH2 storage and marine transportation applications.
