How to stainless steel screws, screw processing manufacturers to teach you!

Although stainless steel is called stainless steel, it is by no means free from rust. When we use stainless steel screws It is necessary to know how to avoid rusting of the product. In the process of use, rust is a common phenomenon, and it is also something that annoys us, which 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. The following are the four points summarized by the screw processing manufacturer for your reference:

1. In polluted air (such as atmosphere containing a lot of sulfide, carbon oxide, nitrogen oxide) , In case of condensed water, the formation of sulfuric acid, nitric acid, acetic acid liquid point, causing chemical corrosion.

2. Organic juices (such as vegetables, noodle soup, sputum, etc.) adhere to the surface of stainless steel screws, and when there is water In the case of oxygen, organic acids are formed, and organic acids will corrode the metal surface for a long time.

3. The attachment of dust or foreign metal particles, in the humid air, the attachment and the stainless steel screw The condensed water connects the two into a micro-battery, which triggers an electrochemical reaction and damages the protective film, which is called electrochemical corrosion.

4. The stainless steel surface adheres to substances containing acids, alkalis, and salts (such as lye water, lime for wall decoration, etc.) water splash), causing localized corrosion.
