YG546 Cemented Carbide Cutting Inserts Introduction

YG546 cemented carbide cutting insert, having a density of 14.55 ~ 14.75g/cm ³, flexural strength of not less than 2700 N / MM ², hardness of not less than 90.5HRA. Cemented carbide cutting inserts due YG546 toughness, high strength to withstand a greater impact load. So YG546 carbide cutting inserts are widely used in stainless steel and cast iron roughing. If required YG546 coated carbide cutting inserts, it is possible to increase the hardness and provide lubrication, but also provide a diffusion barrier for the substrate to be exposed to high temperature to prevent oxidation. Cemented carbide substrate for coating performance is critical. In addition to the main features of the custom matrix powder, but also to select and change the surface chemical properties of the sintered substrate of custom method. By migrating cobalt in the outermost surface of the blade within the thickness of 20-30μm enriched relative to the remaining parts of the workpiece more of cobalt, the substrate surface to impart better strength and toughness, it has a strong resistance to deformation.
