Latrobe Double Six™ ASTM M2 High Speed Steel
Categories:	Metal; Ferrous Metal; Alloy Steel; Carbon Steel; High Carbon Steel; Tool Steel
Material Notes:	DOUBLE SIX (M2) is a tungsten-molybdenum high speed steel with a well balanced composition suitable for a wide variety of applications. World wide, the M2 type is by far the most popular high speed steel having replaced T1 high speed in most applications because of its superior properties and relative economy. Typical applications for Double Six high speed steel include twist drills, taps, milling cutters, reamers, broaches, saws, and knives. Information Provided by Timken Latrobe Steel. Timken sold Latrobe in December 2006. They are now Latrobe Specialty Steels Co.
