Resumen: Hydrogen embrittlement of verious sensitizated stainless steels was compared with actual defects found in components of PWR or BWR type nuclear plants. Hydrogen charging was performed at 300°C by electrolysis in a bath of molten salts. Impact toughness instrumented tests were carried out at -180°C. It was found that hydrogen affects mainly cohesion of the austenite grain boundaries. In order of importance other paths of fracture were detected : boundaries of annealing twins, 8 phase and inclusions - matrix interfaces.
