A predictive rule for long-term creep data, necessary to determine S t of the ASME Code, was proposed with special reference to a Cr-Mo-V steel. This rule can predict long-term creep curves as well as rupture lives. A creep curve three hundred times longer than the longest test was estimated without unreasonable extrapolation.
