Material requirements for threaded rods


It can be seen from threaded rod 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-resistant and long life;
3) Corrosion resistance, the material is corrosive;
4) High strength, can withstand large torque and high speed;
5) Has good cutting performance;
6) The residual stress after heat treatment is small, and the thermal deformation is small.
