In the past decades, tempered martensitic ferritic steels with 9-12% chromium and containing carbide stabilizing elements have been widely used for components which operate within the creep range in power and industrial processing plants. The investigated samples made of X20CrMoV12-1 steel were taken from the main steam pipeline in thermal power plant after 250.000 h (545°C and 19MPa). The low values of impact toughness are the consequence of aging and weakening of grain boundaries, despite the fact that aging processes have not significant effects on the microstructural degradation and drop of the other mechanical properties.
