Cemented carbide wear-resistant discs are required to have better 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 use alloy grades with high hardness, wear resistance and impact resistance, such as YG8, YG11, etc.
2. When selecting alloy grades, it is necessary to meet the specific use requirements according to the processing objects and processing working conditions.
3. If the selected grade is prone to early cracking and damage during use, it is advisable to choose a grade with higher toughness.
