It is important to be able to predict the creep life of materials used in power plants. Levi De Oliveira Bueno has suggested an equivalence between creep and high temperature tensile testing for 2.25Cr-1Mo steel. This offers the potential for reducing the development cycle for new materials designed to operate at ever higher temperatures. This paper reviews the literature to identify some suitable statistical tests for this equivalence. When applied to 2.25Cr-1Mo steel, it was found that this equivalence was only valid if the Monkman-Grant exponent equalled −1. However, this constraint was not accepted by the data based on the proposed statistical tests, and when this constraint was relaxed the equivalence between these different types of test data disappeared.
