How to prevent stainless steel fasteners from rusting and do four things well to save worry

Fasteners include high-strength bolts, high-strength nuts, steel structural bolts, steel structural nuts, and special-shaped bolts and nuts

Although stainless steel is called stainless steel, it is by no means rust resistant. When using stainless steel fasteners, we must know how to avoid product rust.

Rust is a common phenomenon and a concern during use, as it not only affects the aesthetics but also affects the performance of stainless steel screws. Therefore, we must pay attention to the key points in using stainless steel screws. The following are four points summarized by the editor for your reference:

1. In polluted air (such as atmospheres containing a large amount of sulfides, carbon oxides, and nitrogen oxides), condensation water forms sulfuric acid, nitric acid, and acetic acid droplets, causing chemical corrosion.

2. The surface of steel structural screws adheres to organic juices (such as melons, noodles, phlegm, etc.), which, in the presence of water and oxygen, form organic acids. Over time, organic acids corrode the metal surface.

3. The attachment of dust or heterogeneous metal particles, in humid air, and the condensate of stainless steel screws, connect the two into a micro battery, which causes electrochemical reaction and damages the protective film, which is called electrochemical corrosion.

4. The adhesion of stainless steel surface contains acid, alkali and salt substances (such as the splashing of alkaline water and Limewater for wall decoration), causing local corrosion.
