What should you pay attention to when using stainless steel screws?
The stainless steel screw refers to the shape of a screw made of stainless steel screw wire piercing, and then the thread is licked. Its material is stainless steel. Stainless steel screws are made of stainless steel SUS201 screws, stainless steel SUS304 screws, stainless steel SUS316 screws, etc.
In daily life, stainless steel screws are common fasteners. During use, rust is a common phenomenon and it is also a trouble for us. This will not only affect the aesthetics, but also affect the performance of stainless steel screws. .
Therefore, we must pay attention to the use points in the process of using stainless steel screws:
1. The surface of the stainless steel screw adheres to the organic juice (such as melon, noodle soup, glutinous rice, etc.), and in the case of water and oxygen, it constitutes an organic acid, and the organic acid corrodes the metal surface for a long time.
2, the attachment of dust or heterogeneous metal particles, in the humid air, the condensate of the attachment and the stainless steel screw, the two are connected into a micro-battery, causing an electrochemical reaction, the protective film is destroyed, called the electricity Chemical corrosion.
3. In polluted air (such as the atmosphere containing a large amount of sulfide, carbon oxide, nitrogen oxide), in the case of condensed water, sulfuric acid and acetic acid are formed, causing chemical corrosion.
4. The surface of the stainless steel adheres to acid, alkali and salt substances (such as alkali water and lime water splashing on the wall), causing local corrosion.
5. Stainless steel screws need to be strengthened during storage.
6. Stainless steel screws should be handled with care during handling to prevent excessive friction of the friction of the screw fasteners.
7. Stainless steel screws or stainless steel bolts should be aware of the performance of the matching screws and the reasonable cooperation if they encounter the nuts, washers and other connecting parts that need to be used together.
8. Stainless steel screws should pay attention to the correct use of the products during use to ensure that stainless steel screws are not damaged due to improper use.
