TM52 Titanium carbide-based cermet cemented carbide products are characterized by: hardness can not be higher than HRC62, HRC60 is best because it is combined with high manganese steel substrate, has a characteristic, in a strong impact, extrusion conditions , The surface of the rapid occurrence of hardening phenomenon, so that while maintaining toughness and plasticity at the same time hardening layer has a good wear resistance. If the TM52 titanium carbide-based cermet cemented carbide rod itself is too high hardness, in the course of the use of crisp, the phenomenon of fracture.
