The purpose of the project is to develop and deploy high-temperature corrosion-resistant alumina-forming austenitic (AFA) steels into turbine and other energy-related applications (e.g. chemical process industry) in order to improve engine efficiency and/or durability at a potentially lower cost than current alloys. An increased database of the properties and performance of wrought and cast AFA steels will enable additional U.S. industrial partners to employ these materials in applications including fuel cells, boilers and chemical processing. AFA steels are a low-cost, high-performance alternative to conventional advanced austenitic steels and Ni-base alloys. The use of AFA steels, for example, can lead to turbines with increased energy efficiency, lower cost and higher durability that will improve the competitiveness of U.S. turbine manufacturers.
