Tungsten Carbide High Carbon Steel Wire Drawing Die Manufacturer

Under the wear-resistant working conditions of impact or strong impact, the Cemented Carbide Die requires good impact toughness, fracture toughness, fatigue strength, bending strength and good wear resistance.
1. Medium and high cobalt and medium and coarse grain alloy grades are usually selected, such as YG15C, YG20C, YG25C, etc. To
2. The relationship between the wear resistance and toughness of cemented carbide is contradictory: the increase in wear resistance will lead to a decrease in toughness, and the increase in toughness will inevitably lead to a decrease in grindability. Therefore, when selecting alloy grades, it is necessary to meet the specific use requirements according to the processing object and processing working conditions.
3. If the selected grade is prone to early cracking and damage during use, a grade with higher toughness should be selected; if the selected grade is prone to early wear and damage during use, it should be selected with higher hardness and good wear resistance. Grade.
4. The following grades: YG15C, YG18C, YG20C, YG22C, YG25C From left to right, the hardness decreases, the wear resistance decreases, and the performance improves; on the contrary, the opposite is true.

1. Using 95% high-purity raw material tungsten carbide powder and cobalt.
2. The hardness of the cold heading mold is as high as HRA 90 degrees or more, and the bending strength reaches 2520.
3. It has high wear resistance and impact resistance.
