What is the difference between hard alloy steel and high speed steel?
1, two kinds of material composition is different: the former WC+Co+TiC, etc., the latter is generally C+Cr+W+Mo+v2, forming methods are generally different: hard alloy is powder metallurgy process (of course, some are powder metallurgy high speed steel)
3, hardness is not the same: cemented carbide hardness, especially at high temperature hardness, but high-speed steel toughness better4, can withstand the cutting speed is not the same: due to the red hard high, can withstand higher cutting speed, and high-speed steel is now not high speed
5, the scope of application is not the same: the general tool materials used carbide, complex difficult to shape, or require very sharp, high toughness and other field applicable high-speed steel
