  • High Fracture
    Toughness

PRV Series is particularly characterized by high toughness by adopting ultra-coarse grained WC. Furthermore, it also excels in seizure resistance by adding low-friction to RX Series while retaining the original characteristics. It is suitable for applications such as irregular-shaped die molds where stress is concentrated locally.
