Detailed Description
1. W18Cr4v, a tungsten high speed steel commonly used, it belongs to the ledeburite steel, is a kind of high speed steel used the longest. Like other high speed steel, often called the "white steel", "Feng Steel" or "wind steel" (air cooling can quench).
2. Chemical composition:
C : 0.7 - 0.8%, W:17.5 - 19%, Cr:3.80 - 4.4%, V:1 - 1.4% ,
V: less than 0.4%, Mn: less than 0.4%, Mo: less than 0.3%.
3 .Red hardness:
The cutting temperature of 540 degrees, the hardness can keep HRC66
The cutting temperature of 600 degrees, the hardness can keep HRC63
4. Advantages: strong versatility, mature technology.
5. Shortcomings:
Carbide segregation, thermoplastic low hardness and red hardness, cutting tool can not meet the needs of machining hard and tough materials.
The 6 cutting speed: 80 m / S (600 degrees Celsius).
6. Use: small tool shape complex.
7. W18Cr4V tungsten high speed steel, with high hardness, red hardness and hot hardness. The heat treatment of a wide range of quenching is not easy to overheat, heat treatment process is not easy to oxidation and decarbonization, grinding performance. The steel hardness at 500 ℃ and 600 ℃ respectively at HRC57 ~ 58 and HRC52 ~ 53, for large, the processed material has good cutting performance.
