Abstract : Daido Steel is the largest specialty steel maker in the world, and therefore has a strong interest in aerospace materials, such as heat and corrosion resistant steels, and Ti and Ni-based alloys. Daido Steel features some of the most advanced melting and processing equipment and practices available, and appears to be constantly upgrading their facilities and capabilities. Daido Steel has recently designed and is now testing an in-house developed unique spin forming press, designated the SRH, for Spinning and Rolling - Hot. This unique press allows for complex case and ring production in a single work piece, with the ability to produce both variable diameter and thickness with good precision. Additionally, utilizing it's high speed rotary forge, the Shibukawa Plant has unique capabilities for producing very large turbine shafts economically. Several Ti alloy/part development programs currently underway are also reviewed. (MM)
