The existing length of the materials development cycle is currently far too long. Validation of a new methodology to reduce this time requires evidence of its applicability to a wide range of materials. This study focuses on 18Cr–12Ni–Mo steel because of its importance to future power generation. The methodology is shown to accurately predict the strengths of numerous batches of this material obtained from different test facilities out to 100,000 h by analysis of short-term tests from just a single batch of this material. This may justify rapid prediction of 100,000 h strengths for newly-developed austenitic products, such as Save25, Sanicro 25 and BGA4, for which the absence of long-term creep design data now prevents their plant adoption.
