Stainless steel screw use points

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.). In the case of water and oxygen, it constitutes an organic acid. For a long time, the organic acid corrodes the metal surface. 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, acetic acid liquid point is 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.
