Mechanical properties of candidate materials for hydrogen container were studied in high pressure of gaseous hydrogen by using newly designed and installed facilities. Tensile properties, slow strain rate tensile properties, fatigue properties and fatigue crack growth properties of aluminum alloy AA6061-T6 and austenitic stainless steel of type 316L in 45 MPa gaseous hydrogen were similar to those properties tested in air. These data can give guideline not only to the reference standard and technical standard dealing with 35 MPa-class compressed hydrogen container but to future material development of various apparatuses for hydrogen.
