Summary

A new type of apparatus for materials testing in high pressure hydrogen up to 10 megapascals at low temperatures down to 20 K was developed. The apparatus consists of a pressure vessel, cooled by a two-step external cooling method, and a hydraulic loading system. As an example of the application of the apparatus, the tensile properties of type 304L stainless steel in 1 megapascal hydrogen and helium at low temperature are measured and hydrogen environment embrittlement of the steel is briefly discussed.
