The selection of stainless steel screws is mainly considered from the following five aspects.
1. Requirements for the corrosion resistance of materials under working conditions;
2. Requirements for the mechanical properties of the material, especially the strength;
3. The requirements of the working temperature on the heat resistance (high temperature strength and oxidation resistance) of the material;
4. Requirements for material processing performance in terms of production process;
5, other aspects, such as weight, price, procurement factors must be considered.
