: Data confirms that high-pressure hydrogen has minimal influence on the alloy’s fracture elongation (34–36%), demonstrating superior resistance to embrittlement compared to standard alloys.

: Tensile testing conducted in pressurized gaseous hydrogen (GH2) at up to 5 ksi. Results & Discussion : hr2.zip

: The alloy maintains an ultimate tensile stress of approximately 165 ksi. : Data confirms that high-pressure hydrogen has minimal
