Screw the material requirements

ZHENYA FASTENER | Updated: Aug 14, 2015

By the extrusion process, screw at high temperature, corrosion, wear strong, working under high torque, so screw you must:

1) high temperature resistance, high temperature deformation;

2) abrasion resistant, long service life;

3) corrosion-resistant, the material is corrosive;

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

5) has good machinability;

6) after heat treatment, residual stress and thermal deformation is small, and so on.
