Abstract: The influence of hydrogen on the strength and ductility of 30KhGSA and EI659 steels in quasi-static and shock-wave tests was studied experimentally. The sensitivity of the steels to hydrogenation in air under normal pressure or in hydrogen at a pressure of 25 MPa was determined from the results of tests of samples in the initial state and samples pre-hydrogenated at a temperature of 773 K and a hydrogen pressure of 50 MPa for 24 h. It is found that EI659 steel doped with tungsten and vanadium is less sensitive to to hydrogen than 30KhGSA steel doped with manganese and chromium.

Keywords: strength, ductility, steel, hydrogen, quasi-static and shock-wave tests.
