PRODUCT INTRODUCTION
Cemented Carbides with Excellent Duability for Warm/Hot Forging Application
W Series
- Corrosion
Resistance - Impact
Resistance - Oxidation
Resistance - High Fracture
Toughness - Hot Forging
W Series excels in wear and oxidation resistance at high temperatures. Even when used under harsh high-temperature conditions, oxidative wear is less likely to occur, contributing the longevity of molds.
