High pressure hydrogen tensile test
WebMar 4, 2024 · As mentioned above, the study of hydrogen-resistant materials for high-pressure hydrogen environments indicates that high-strength steels may replace austenitic stainless steels in hydrogen energy systems. Unfortunately, high-strength steels are more likely to suffer from HE than austenitic stainless steels. Webtemperatures [7-9] down to 80 K under 1.1 MPa gaseous hydrogen. However, no tensile or fatigue data is available neither for the higher pressure hydrogen and low temperature environments nor fatigue properties.
