Grade available:

1. Standard grade: 38CrMoAlA + nitriding 96 hours
2. Bimetallic grade: 38CrMoAlA + bimetallic alloy
3. TC-A grade: Tungsten carbide 40%
4. TC-B grade: Tungsten carbide 25%
5. TC-C grade: Tungsten carbide 9.5%

With the development of varieties of plastics, more and more customers are requesting for bimetallic screw to extend the

lifetime of the screw.

Normally we do PTA weld spray coating for the bimetallic screw. And we apply Stellite alloy powder which is in high wear

resistance and corrosion resistance.
