Crucible CPM® Rex M4 HC(HS) Tool Steel

 

Subcategory: Tool Steel; High Carbon Steel; Metal

Close Analogs:

Composition:
Iron content calculated as remainder

Material Notes:
CPM REX M4 HC(HS) is a high vanadium special purpose high speed steel exhibiting better wear resistance and toughness than M2 or M3 in cold work punches, die inserts and cutting applications involving high speed and light cuts.

The high carbon (HC) modification to standard M4 is designed to provide optimum hardening response in larger cross-section tools or in vacuum or atmosphere heat treating.

The high sulfur (HS) modification is standard for larger diameter bars, providing enhanced machinability and grindability.

The CPM process produces very homogeneous, high quality steel characterized by superior dimensional stability, grindability, and toughness compared to steels produced by conventional processes.
