Carbide punch die are required to have good impact toughness, fracture toughness, fatigue strength, bending strength and good wear resistance under the wear-resistant working conditions of impact or strong impact.
1. Usually select medium and high cobalt and medium and coarse grain alloy grades, such as YG15C, YG20C, YL60, YG25C, etc.
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 abrasiveness. 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 better wear resistance Grades.
