Stainless steel generally refers to steel that has the ability to resist corrosion by air, water, acid, alkali salt or other media. According to the different alloy components, the focus is on rust resistance and acid resistance.

The production fasteners are mainly austenitic stainless steel. In people’s daily life, the stainless steel that is 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 screws are mainly used for:

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.

In daily life, stainless steel screws are very common fasteners. In the process of use, people also found that it is prone to the following problems.

One, loosening problem

When using stainless steel screws, screw loosening is a very common problem. Under certain shocks and vibrations, it will become more and more loose.

Second, the problem of blackening

The beginning of the blackening of stainless steel screws is that the screw has too high displacement during the process of screwing or cold heading.

In addition, the material of the screw itself will also cause the screw to turn black, and the blackened part is mainly manifested in the cross groove part.

Third, the corrosion problem

Stainless steel screws can also corrode. Many factors can cause corrosion damage to stainless steel screws. Some air containing carbon oxide, sulfuric acid and other substances can cause screw corrosion. Dust and moisture in the air can cause chemical corrosion. The top of the screw surface After the organic matter is cut, it will also cause damage to the screws.

Fourth, the fracture problem

Generally, stainless steel screws are not prone to breakage. The main reason for the breakage of the screw is that the quality of the material itself is not good, or the processing technology is unreasonable. In addition, if the user uses the screw too hard, it may also cause the screw to break.
