Generally, we can judge whether the quality is high-quality products from the following five aspects:
1. The requirements of stainless steel screw material in mechanical properties, especially in strength;
2. The requirements of working conditions on the corrosion resistance of materials;
3. The requirements of working temperature on the heat resistance (high temperature strength, oxidation resistance) of the materials;
4. The requirements of production technology on the processing performance of stainless steel screw materials;
5. Other factors, such as weight, price and purchase, should be considered.
