Products Description
Stainless Steel Fastening Spot Welding Screw usually refer to steel screws that have the ability to resist corrosion by air, water, acid, alkali salt or other media. Stainless steel screws are generally not easy to rust and are durable, and can be used in environmental protection equipment, medical equipment, communication equipment and other fields.
According to the different alloy components, the focus is on rust resistance and acid resistance. Although some steels are rust-proof, they are not necessarily acid-resistant, and acid-resistant steels are usually rust-proof. In people's daily life, the stainless steel often referred to is also austenitic stainless steel. The stainless steel fasteners we use mainly use austenitic 302, 304, 316 and "low nickel" 201 as raw materials.
Stainless Steel Fastening Spot Welding Screw Collapse edit the scope of application of this paragraph
Mainly used for: environmental protection equipment, medical equipment, communication equipment, power facilities, electronic products, instrumentation, food machinery, petrochemical industry, ship assembly, pump valve pipeline, building curtain wall, open air, sports facilities, outdoor decoration, etc.
Selection principle
Principles of selection of Stainless Steel Fastening Spot Welding Screw:
The choice of stainless steel materials is mainly considered from the following five aspects.
1. Requirements for the mechanical properties of stainless steel screw materials, especially strength;
2. The requirements of working conditions on the anti-corrosion performance of materials;
3. The requirements of the working temperature on the heat resistance of the material (high temperature strength, oxidation resistance);
4. Requirements for material processing performance in terms of production technology;
5. Other aspects, such as weight, price, purchase and many other factors must be considered.
