Industry knowledge：

How to choose the material for precision screws?

1. There are provisions on the performance of mechanical equipment and compressive strength of precision screw materials
2. Provisions on corrosion resistance of materials
3. Regulations of operating temperature on high temperature resistance (high temperature compressive strength, oxidation resistance) of materials
4. Regulations on production and processing performance of materials at the level of production process flow
5. Other factors, such as net weight, price, purchase and so on, should be taken into account
