Grade: HSF928 Metal content: 99.96 impurity content: 0.4 Uses: It is high speed milling grain size of ultrafine grades, suitable for low-alloy steel, high alloy steel, titanium, stainless steel, heat-resistant alloys, hardened steel, gray cast iron, glass fiber reinforced plastic and other materials processing. Carbide is manufactured by powder metallurgy method chromium-molybdenum alloy, wherein the binding phase steel containing TiC as hard phase. Its performance between steel and cemented carbide, and is available for quenching and other heat treatment, machining alloy steel so convenient, but is much higher hardness than steel.
