CPM REX M-4
CPM REX M-4® Powder Metal
CPM REX M-4® high speed steel is an extremely versatile high speed steel which provides a unique combination of high wear resistance with high impact toughness and transverse bend strength. A large volume of vanadium carbides provides the high wear resistance. The high impact toughness and high transverse bend strength are results of the fine grain size, small carbides, and superior cleanliness of the powder metallurgy (CPM®) microstructure. CPM REX M-4® offers improved cutting tool life compared to conventionally wrought M-1, M-2, M-7 and other lower-alloyed high speed steels. CPM REX M-4® also excels in cold work tooling applications where it provides better toughness and wear resistance than high-carbon, high-chromium die steels such as D-2 and D-3.
