Products Description
What Is CPM REX M4? often called simply PM M4 steel, is a special-purpose type of high speed steel. It is noted for its wear-resistance characteristics. It has very high carbon and vanadium contents. It is an excellent choice for premium cutting tools such as those used on abrasive alloys, heat-treated materials and castings.
This type of steel provides a distinctive combination of malleable strength, high-impact toughness and extreme wear resistance. The high percentage of vanadium carbides provides the high wear resistance and the fine grain size provides extreme toughness and bending strength.
It is designed to provide an optimum hardening response when treated with vacuum or atmosphere heat methods. Further, this steel performs exceptionally well in cold work tooling applications, outperforming most other high-carbon, high-chromium die steels.
Common Applications for PM M4 High Speed Steel
High-speed steels such as CPM Rex M4 high speed steel rod can be used in a multitude of applications. Durable steels are routinely used to create industrial tools that need to withstand environmental and working condition stresses.
Tools that feature high-speed steels include drill bits, taps and hammers. Other applications include high-impact construction, aerospace engineering, manufacturing, tooling and automation.
High speed steel offer exceptional hardness and wear resistance, with various grades for toughness or reduced brittleness. Thus, these steels types are commonly used in industrial cutting devices such as milling cutters, saw blades, broaches and more.
These are a few common uses for REX M4:
Form tool manufacturing
Punch manufacturing
Broach inserts
End mill manufacturing
Taps
Header tooling
