F Superalloy Case Study BACKGROUND This case study examines the status of the superalloy industry in the United States and abroad today. It is based on data gathered in personal interviews1 and from other sources.2 In particular, this case study examines companies in the United States that melt and produce superalloy materials, that cast parts from superalloys, or that use superalloys.
