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 dissimilar metal particles in humid air, combined with the condensed water of stainless steel screws, forms a micro battery, triggering an electrochemical reaction and damaging the protective film, which is called electrochemical corrosion.

4. The surface of stainless steel adheres to substances containing acids, alkalis, and salts (such as alkaline water and lime water splashing during wall decoration), causing local corrosion.
