Rex 49 is a high-speed tool steel designed to give much longer life in machining difficult to cut metals such as highly-alloyed steels, stainless steels, superalloys, and titanium. Rex 49 heat treated to 67/69 Rockwell C makes it outstanding for difficult machining operations. This datasheet provides information on composition, physical properties, hardness, elasticity, and compressive strength. It also includes information on forming, heat treating, and machining. Filing Code: TS-114. Producer or source: Crucible Steel Company of America.
