Stainless steel screw usually refers to the steel screw which has the ability to resist the corrosion of air, water, acid, alkali salt or other media. The main raw materials are austenite 302, 304, 316 and "low nickel" 201.
Stainless steel screw is not easy to rust, durable, can be used in environmental protection equipment, medical equipment, communication equipment and other fields.
Material selection principle of stainless steel screw:
The selection of stainless steel materials is mainly considered from the following five aspects.
1. Requirements for mechanical properties, especially strength of stainless steel screw materials;
2. Requirements of working conditions on corrosion resistance of materials;
3. The requirements of working temperature on heat resistance (high temperature strength, oxidation resistance) of materials;
4. Requirements of production technology on material processing performance;
5. Other aspects, such as weight, price, purchase and many other factors should be considered.
