CPM Rex 76 High Speed Steel Composition
CPM Rex76 super high speed steel is a high-performance high speed steel which exhibits superior hot (red) hardness compared to T15 and M42 high speed steels. Can be heat treated to 70 HRC, and the high cobalt content enables the steel to maintain high hardness at elevated service temperatures. Vanadium carbides provide the high wear resistance, and the fine grain size, small carbides, and superior cleanliness of the powder metallurgy (PM) microstructure maximize the toughness of the steel. Offers improved cutting tool life compared to the M-series high speed steels.
