82-85HRA Tungsten Carbide Cold Heading Blank Die for Bolts And Nuts
Tungsten carbide cold heading die is widely used in cold heading machine as machine mold core material.
With high hardness and impact strength and good wear resistance, they are used in different working conditions for processing di
Different materials.We have grades with different hardness :
G40 G45 Tungsten Carbide Cold Heading Die for Multi Stations Cold Heading Machine
The advantage charactors of tungsten carbide cold heading die
High density
The density of tungsten carbide cold heading dies ranges from 13.3 to 14.5g/ cm^3
This determines its high hardness and good wear resistance,suitable to be used in forming steel wire products.
2.High Hardness
The regular hardness for tungsten carbide cold heading die includes 82HRA, 83HRA,84HRA,85HRA.
Widely used in Multi-station cold heading machines as molds core.
3.High impact strength
The particle size decides the impact strength of the carbide.The smaller of the particle size is, the impact strength is lower
4.Good wear resistance
The particle size and the structure of the powder determines the wear resistance of the tungsten carbide products.
Tungsten carbide hot forging die are widely used in hot forging industry.
ardness is 83.5 HRA for HRS7, Which is used in forging M16-M30 bolts and Nuts at high temperature.

During the cold heading process of standard parts, the cemented carbide cold heading die has to withstand large impact forces. In order to meet the usage requirements, it is necessary to choose cemented carbide with high cobalt content, high strength and good impact toughness.
Carbide heading dies have replaced steel dies for process steel and non-ferrous metals. They have the advantages of high hardness, toughness and good wear resistance, we have independently developed 48 Grades for your choice suitable for various working conditions.
