Abstract

The 9-12% Cr family of ferritic steel is emerging as one of the most important groups of materials for power engineering applications with higher steam temperatures. The materials are at the stage of development where several different steels, with slight but important variations in composition, have been produced and data on mechanical properties at high temperature have been collected. COST 501 has included a significant effort on these materials involving the turbine builders and boiler-making companies and one aim of the survey was to place the COST work within the context of worldwide activity. Another objective was to assess critically the published information on the microstructure and performance of various steels in the different compositional categories. Particular attention was given to the requirements of large steam turbine rotors. The report summarizes and illustrates all the data considered from sources in the USA, Japan and Europe and a full list of references is included. Deficiencies in the data are highlighted and recommendations are made regarding future research activities in Europe which include the in-depth evaluation of forgings with selected composition types.
