 Performance and application: 

 Tungsten-molybdenum high-speed tool steel commonly used, even small carbide, high toughness, thermoplastic. As the thermoplastic of the steel, so the shape can be thermoplastic, but because of easy oxidation and decarbonization, heating must be taken to protect. 

 In addition to the general tools used in the manufacture of various types, can also be used in the manufacture of large tools.
