TWM80 is a Cemented Carbide with improved oxidation resistance based on cemented carbides with superior in heat-shock resistance. It has contributed to long tool life by restraining oxidative wear and strength degradation under warm/hot temperature condition. It is suitable for forging tools or shearing tools under warm/hot temperature condition.
