1.3243die steel
Detailed Introduction:
Characteristics and Scope of Application:
For tungsten molybdenum series general cobalt containing high-speed steel, the red hardness and high temperature hardness have been increased, the wear resistance has been improved, and it has good cutting performance, but the strength and impact toughness are low, and it is easy to oxidize and decarburize. It is generally used as a gear cutting tool, milling tool, punch, tool head and other tools for cutting hard materials。
