Technical Characteristics
According to GOST, steel with cobalt content of at least 3% is used for tool reinforcement. But if the cobalt content is more than 20%, the hard alloy becomes brittle and the increased tool wear is observed. The use of tungsten carbide alloys requires careful observance of production technology.
Using
Tool production for machining parts made of structural steel, when working through impact, interrupted cutting. Such tools can be used for machining titanium alloys and stainless steel, heat-resistant and high-strength steel.
Quality requirements
According to GOST, the surface of carbide plates - ground, smooth, no cracks, grease, burrs, chips, grease spots.
