  It can be seen from the extrusion process that the screw works under high temperature, certain corrosion, strong wear and high torque. Therefore, the screw must:

  1. High temperature resistance, no deformation at high temperature

  2. Wear resistance and long life

  3. Corrosion resistance, the material is corrosive

  4. High strength, can withstand large torque and high speed

  5. It has good cutting performance

  6. Small residual stress and small thermal deformation after heat treatment
