Characteristics
-
- Hardness and Fracture Toughness of RF・Series
- RF Series offers improved high hardness and fracture toughness in comparison with conventional ultrafine grained Cemented Carbide (WC-Co).
-
- RF20 Microstructure
Chipping Resistance Evaluation
-
- Chipping of conventional ultrafine grained Cemented Carbide (WC-Co)
- Chipping of RF20
As a result of chipping test by adding overstress on the edge part, RF20 offers improved chipping resistance comparing to that of conventional ultrafine grained Cemented Carbide (WC-Co).
