In hydrogen energy, petroleum and chemical industries the bearing parts in high pressure hydrogen systems are prone to hydrogen-induced damage due to the coupling effect of manufacturing residual effects, high-pressure hydrogen and complicated loadings. In order to ensure long-term, stable, safe and reliable operations of the high-pressure hydrogen system, it is necessary to provide the data of material properties for the development of high-pressure hydrogen system products. Considering the independence and extendibility of data, a database for mechanical properties of metallic materials in high-pressure environment is developed with VB programming language. based on the materials data previously obtained in high-pressure hydrogen environments (slow strain rate tension test, fracture toughness test and fatigue crack propagation test). The analysis of the database, which combines domestic and foreign researches and applications, has shown its versatility and comprehensiveness in terms of metal material hydrogen embrittlement data.
