   High-speed steel is a high-alloy steel with the addition of tungsten, molybdenum, chromium, vanadium and other alloying elements. High-speed steel has a high strength, bending strength of the general carbide 2 to 3 times; toughness is also high, several times higher than the carbide. High-speed steel hardness above 63HRC, and have good heat resistance, cutting temperature reached 500 ~ 650 ° C, still able to cut. High-speed steel can be machinable, heat treatment deformation is small, is currently used in the manufacture of various complex tools (such as drill, tap, broach, forming tools, gears, etc.). High-speed steel cutting tools can be processed from non-ferrous metals to high temperature alloys. Table 2-15 lists the grades of several commonly used high speed steels and their main applications, which are available for selection.
