How to prevent stainless steel fasteners

Although stainless steel is called stainless steel, it is definitely not rust-free. When using stainless steel fasteners, we must know how to avoid product rust. In the process of use, rust is a common phenomenon, and it is also an annoying thing 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 key points in the use of stainless steel screws. The following are the four points summarized for your reference:

1. In polluted air (such as the atmosphere containing a large amount of sulfide, carbon oxide, and nitrogen oxide), it will form sulfuric acid, nitric acid, and acetic acid liquid spots when encountering condensed water, causing chemical corrosion. (Guide: How to take a high-strength bolt after it is broken?)

2. The surface of the stainless steel screw adheres to the organic juice (such as melon, vegetable, noodle soup, sputum, etc.), which forms organic acid in the presence of water and oxygen, and the organic acid 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 condensed water of the stainless steel screw, connect the two into a micro battery, triggering an electrochemical reaction, and the protective film is damaged. It is called electrochemical corrosion.

4. The surface of stainless steel is adhered to contain acid, alkali, and salt substances (such as alkali water and lime water splashing on the decoration wall), causing local corrosion.
