    Product Specification

    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. Aim hardness is 63/65.

    CPM REX M4 is a registered trademark of Crucible Industries LLC.

    Typical chemistry: C 1.42, Mn .30, S .06, Cr 4.00, V 4.0, Mo 5.25, W 5.5
