Methodological Aspects of Determination of Hydrogen Resistance of Steels

We consider main conditions of the adequate estimation of degradation of mechanical properties of chromium–nickel alloys in gaseous hydrogen. We establish that evacuation is a necessary procedure for preparing a working chamber for testing. The low-cycle fatigue and relative contraction are the most sensitive to hydrogen embrittlement. We determine the strain rate and hydrogen pressure that maximally impair mechanical properties.
