There is significant interest in the development of wrought and cast alumina forming austenitic (AFA) stainless steel alloys for use in various industrial process environments. Earlier studies of wrought AFA alloys showed that these alloys achieve good high-temperature oxidation resistance due to the formation of protective Al2O3 scales while multiple second-phase precipitation strengthening contributes to excellent creep resistance. This work will present the progress in the design and development of cast alloys. These alloys were initially designed using small laboratory scale heats and subsequently fabricated in the form of centrifugal castings. Particular emphasis will be placed on the computation-aided approach used in the development of these alloys and the need for the development of additional tools that can benefit the development of these and similar alloys. Research sponsored by the U.S. Department of Energy, and The Technology Innovation Program (TIP) under contract DE-AC05-00OR22725 with UT-Battelle, LLC.
