PRODUCT INTRODUCTION
Low Friction Cemented Carbides with Excellent Duability for Warm/Hot Forging Application
PWM Series
- Corrosion
Resistance - Impact
Resistance - Seizure
Resistance - Oxidation
Resistance - High Fracture
Toughness - Hot Forging
PWM Series adopts ultra-coarse grained WC and has excellent heat-crack and oxidation resistance. Furthermore, it is a grade added low friction to W Series, and also has excellent seizure resistance while retaining the characteristics of W Series. It is suitable for harsh hot forging applications.
