Latrobe DuraTechâ„¢ M48 Powder Metal High Speed Steel (ASTM M48)

DuraTech M48 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, and wear resistance comparable to that of T15. DuraTech M48 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. DuraTech M48 offers improved cutting tool life compared to the M-series high speed steels. Typical applications include form tools, broaches, milling cutters, hobs, and any special cutting tool where high hot hardness is required.Information Provided by Timken Latrobe Steel.Timken sold Latrobe in December 2006.
