What are the key points to pay attention to when using stainless steel screws?

Stainless steel screws refer to the shape of screws made by beating stainless steel screw wire, and then the thread is rubbed. The material is stainless steel. Stainless steel screws are divided into stainless steel SUS201 screws, stainless steel SUS304 screws, stainless steel SUS316 screws, etc. according to the material.

In daily life, stainless steel screws are common fasteners. During use, rust is a common phenomenon and also a thing that bothers us. This will not only affect the aesthetics, but also affect the performance of stainless steel screws.

Therefore, we must pay attention to the key points of use in the process of using stainless steel screws:

1. Organic juice (such as vegetables, noodle soup, sputum, etc.) adheres to the surface of stainless steel screws. In the presence of water and oxygen, organic acid is formed, and the organic acid corrodes the metal surface for a long time.

2. The attachment of dust or heterogeneous metal particles in humid air connects the attachments and the condensed water of stainless steel screws into a micro-battery, triggering an electrochemical reaction, and the protective film is damaged, which is called electrochemical corrosion.

3. In polluted air (such as atmosphere containing a large amount of sulfide, carbon oxide, and nitrogen oxide), condensed water forms sulfuric acid and acetic acid spots, causing chemical corrosion.

4. Acid, alkali, and salt substances (such as alkaline water and lime water splashing from wall decoration) adhere to the surface of stainless steel screws, causing local corrosion.
