Long-term creep rupture strength prediction for a new grade of 9Cr martensitic creep resistant steel (G115)—An application of a new tensile creep rupture model

A method is presented to firstly rationalise the short-term creep rupture strength data and then to predict the 100,000 h creep rupture strengths of a new 9Cr grade of martensitic creep resistant steels (G115) at different temperatures. The method is made possible by a new tensile creep rupture model, which is formulated by combining a new tensile creep model that integrates tensile strength at creep temperature with the Monkman–Grant...
