Neue Ergebnisse zum Kriech- und Zeitstandverhalten des warmfesten Rohrstahles 15 CrMoV 5-10 : Ergebnisse des VGB-Forschungsprojektes 129

The results of comprehensive investigations carried out over two decades in the creep rate of the heat-resistant pipework steel 15 CrMoV 5 10 are presented. Various methods of evaluation are in use. At the same time, the paper looks into possibilities, which offer a component-specific evaluation of creep strength by means of the Z-Factor concept for the determination of remanent life and rate of depletion.
