Alloy steel is a kind of steel in addition to containing silicon and manganese as alloying elements and deoxidizing elements, but also contains other alloy elements such as chromium, nickel, molybdenum, vanadium, titanium, copper, tungsten, aluminum, cobalt, niobium, zirconium and other elements, and some also contain some nonmetallic elements (such as boron, nitrogen, etc.) of the steel. Alloy steel due to the presence of different kinds and quantities of alloying elements and take appropriate measures in the process, can be respectively, with high strength, toughness, quenching through resistance, abrasion resistance, corrosion resistance, resistance to temperature resistance, heat resistance and other special properties.
Alloy steel bar is mainly applicable to drill, milling cutter, reamer. It can also be used for cutting, stamping and measuring tools. It is used in the paper, packaging, printing, non-ferrous metal processing industry. In addition, it is also widely used for processing high-speed steel cutting tool, hard alloy cutter, hard alloy cutting tools, NAS cutting tool, air tool, hard alloy bit, cutter from core bit, high speed steel, taperd milling cutter, cutter metric, micro end milling cutter, the hinge pilot, electronic tools, drilling ladder, metal cutting saw, double assurance diamond, guns, angle cutter, tungsten carbide rotary burrs, hard alloy cutting tools and so on.
