It can remain 60HRC at temperature ranges 900{-}1000°C 7

HighWear-resistance

The cutting speed of cemented carbide tools is 4-7 times higher than high-speed steel, and the tool life is 5-80 times longer.the tool life could be longer than alloy tool steel 20-150 times if they are used for Manufacturing molds and measuring tools.
