81- 86.5 HRA Tungsten Carbide Seal Rings Excellent Wear Resistance
Tungsten carbide is widely used as seal faces with resistant-wearing, high fractural strength, high thermal conductivity, small heat expansion co-efficient. It is the best material to resist heat and fracture in all hard face materials.
Product Feature of tungsten carbide seal ring
1. Excellent abrasion resistance
2. High wear resistance
3. High fractural strength
4. high thermal conductivity
5. Small heat expansion co-efficient
