Abstract
The paper deals with the influence of the hydrogen on the behaviour of martensitic steel of type 22MnB5. Steels with the high yield strength reveal quite great predisposition for hydrogen present in the structure, so quite non-stable behaviour. Such behaviour increases with material loading, but can also occur even without acting of any outer forces. This process is termed as the hydrogen embrittlement and presents a great risk for structural parts in the whole industrial range. Because of utilization materials that are sensitive to the hydrogen embrittlement already in the advanced safety and strength applications, there is necessary to perform a lot of tests and analysis to eliminate hydrogen activity in metal structure before their application. There are mostly used mechanical tests which loaded sample by the tensile, bending or combine loading. Moreover, by utilization sophisticated devices, there is even possible to detect own hydrogen and determine its amount in the analysed structure.
