CPM high-performance tool and high-speed steels are premier products of Crucible Specialty Metals Division. The process of producing CPM tools involves gas atomization of pre-alloyed molten steel to form powder that is then isostatically compressed into 100% dense compacts. CPM steels have no alloy segregation and exhibit extremely uniform carbide distribution.

This special process creates alloys with unique or enhanced properties that cannot be made by conventional steel manufacturing methods. In almost any application, CPM grades offer improved wear-resistance, toughness and grindability.

In addition, CPM tool steel carbides are extremely fine and uniformly distributed, resulting in superior grinding and heat-treating characteristics. Benefits for the tool user include improved tool performance and ease of regrinding.

Since the introduction of the CPM process in 1970, Crucible has developed a number of grades for high speed and tool steel applications. Among these are CPM H13S, and the vanadium CPM tool steel grades 3V, 9V, 10V, 15V, as well as CPM 420V and CPM 440V.

In the high-speed product area, we produce a number of grades with tooling applications -- CPM Rex M4 and M4HC (HS), CPM Rex 45 (HS)-M3 + Co, CPM Rex 54 (HS) - M4 + Co, CPM Rex 20, CPM Rex T15, CPM Rex 76, and CPM Rex 121.
