Material Notes:
CPM Rex 45 is an 8% cobalt modification of M3 high speed steel made by the CPM (Crucible Particle Metallurgy) Process. It has red hardness comparable to that of M42 but offers abrasion resistance even better than that of M3. With its excellent red hardness, good wear resistance and good toughness, CPM Rex 45 is suitable for difficult machining applications or high cutting speed applications.

The CPM process results in a homogeneous microstructure with a finer, more uniform carbide distribution imparting superior dimensional stability, grindability and toughness when compared to steels produced by conventional processes. The CPM process also allows the design of more highly alloyed grades which cannot be produced by conventional steelmaking.
