bending resistance of the cemented carbide of the pump tube manufacturer?

The article Time : 2019-05-17

Cemented carbide is produced by powder metallurgy from a refractory metal hard compound (hard phase) and a metal binder (bonded phase). A widely used hard compound is a carbide. Commonly used carbides for cemented carbides for cutting tools include tungsten carbide (WC), titanium carbide (TiC), tantalum carbide (TaC), niobium carbide (NbC), and cobalt (Co). The content of Co determines the hardness.we are concrete pump parts sellers.
 The strength of the alloy. The carbides in the pump tube manufacturers have high melting point, high hardness, good chemical stability and good thermal stability. The hard component of the hard alloy is WC.

WC has good wear resistance, high yield strength and plastic deformation resistance, and WC has good thermal conductivity and low thermal expansion coefficient. /3, the modulus of elasticity is 710 GPa.
The hardness of cemented carbide is 89~94HRA, which allows the highest cutting temperature to reach 200~1000°C. The hardness at 540°C is 82~87HRA, and the hardness at 77°C is 77~85HRA. It can be fashionable at 1000~1100°C. Keep 73~76HRA. The wear resistance of cemented carbide is 15~20 times higher than that of high-speed steel. The hardness and wear resistance of cemented carbide are good.

Its cutting performance and durability are several times higher than that of high-speed steel. It is widely used in tool materials. The addition of TiC, TaC or NbC to WC-Co cemented carbide increases the hardness of the cemented carbide. The content of TiC, TaC or NbC added increases, and the hardness of the cemented carbide increases.

TiC is added to the YT type cemented carbide. Therefore, the YT type is harder than the YG hard alloy. The grain size of the carbide in the cemented carbide also affects the hardness. The fine grain and the ultrafine grained cemented carbide A hard alloy with a hardness higher than that of coarse grains and medium grains. The wear resistance of hard alloys with high hardness of pump tube manufacturers is also increased.
