Subway bolts are a common type of fastener in daily life. When using subway bolts, they are prone to rusting, which can affect their appearance and performance. Therefore, when using subway bolts, we must pay attention to their rust prevention. Below, we will introduce the causes of subway bolt rusting. If there is dust or other metal particles adhering to the surface of subway bolts, they will form a micro battery with the condensation of subway bolts in humid air, resulting in electrochemical reactions. In this case, subway bolts will rust.
The surface of subway bolts may be contaminated with organic juices, and subway bolts will form organic acids in the presence of water and oxygen. Under the corrosion of organic acids, subway bolts will rust. If the surface of subway bolts is contaminated with acidic, alkaline or other substances, it can also cause rusting. During use, as long as we pay attention not to let the subway bolts come into contact with these substances, the subway bolts will not rust.
