Grade: G40 Hardness :83-84.5 Flexural strength: 400 Uses: screw die, hot forging dies, impact tools, stainless steel. Carbide tool material type, performance and features carbide tools (especially indexable carbide cutting tools) is the leading CNC machining tool products, some countries more than 90% of turning, milling more than 55% knives are used carbide manufacturing, and this trend is increasing. Since the 1980s, various tool industry continues to expand the overall style and indexable carbide tool or blade-type production, the species has been extended to a variety of cutting tool fields, including indexable carbide cutting tools from simple turning, face milling expanded to a variety of sophisticated, complex, forming cutter fields. Or manufacturing carbide drills, face milling and other materials commonly used generic tool. Meanwhile, reamers, end mills, machining hardened medium and big modulus gear cutters, broaches and other complex tool use carbide are increasing. Currently, carbide cutting tools and blades cutting tool output value accounted for 30% of GDP or more.
