 0.70-0.80 0.15-0.40 3.80-4.40 0.15-0.40 ≤ 0.30 1.00-1.40 17.5-19.0 ≤ 0.030 ≤ 0.030 


 Performance and application: 
 Tungsten high speed tool steel, high hardness, hot hardness and high temperature strength, its wide range of heat treatment, quenching is not easy to overheat, easy-to-grinding, thermal processing and heat treatment process is not easy oxidation and decarbonization. Uniformity of the carbon steel, high temperature plastic than the difference between molybdenum high speed steel, but its wear resistance. 
 Used in the manufacture of cutting tools.
