Author：SGT Source：SGT Date： 2019-11-12

Summary：

It is known from the molding 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 resistant, corrosive materials;

4) High strength, can withstand high torque, high speed;

5) Has good cutting performance;

6) Residual stress after heat treatment is small, thermal deformation is small, and the like.
