Cold heading dies usually use medium and high cobalt and medium and coarse grain alloy grades, such as YG15C, YG20C, YG25C, etc.
The relationship between the wear resistance and toughness of cemented carbide is contradictory: an increase in wear resistance will lead to a decrease in toughness, and an increase in toughness will inevitably lead to a decrease in wear ability. Therefore, when selecting alloy grades, it is necessary to meet specific usage requirements based on the processing objects and processing working conditions.
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, a grade with higher hardness and good durability should be selected.
The following grades: YG15C, YG18C, YG20C, YG22C, YG25C from left to right, the hardness decreases, the wear resistance decreases, and the wear resistance increases; vice versa.
