In fact, many people believe that stainless steel bolts do not rust, but in daily life, sometimes we find ourselves using household appliances or some accessories on doors and windows. In fact, stainless steel bolts have begun to rust, which is why? Next, the manufacturer of stainless steel bolts will take you to have a chat:
Stainless steel screws have strong scandium corrosion resistance, high temperature resistance, and good rust resistance. However, stainless steel screws can still rust in some harsh environments. If they are exposed to long-term humid environments or come into contact with acid and alkali chemicals, they will inevitably be corroded and rust. In addition, rust on stainless steel screws is also related to their own material quality. Poor material quality naturally leads to poor corrosion resistance.
Stainless steel screws have the ability to obtain scandium corrosion by simulating the continuous infiltration and oxidation of oxygen atoms through a thin, solid, fine, and stable chromium rich oxide film on their surface. Once this thin film is constantly damaged due to external environmental factors, oxygen atoms in air or liquid will continue to penetrate, or iron atoms in metal will continue to separate out, forming loose iron oxide, and the metal surface will also receive continuous corrosion.
Overview of stainless steel screw manufacturers: To ensure that the metal surface of stainless steel screws is bright, in daily life, we should often clean and scrub the surface of stainless steel screws, remove attachments, and eliminate external factors that cause corrosion. In addition, when purchasing stainless steel screws, we should also choose a manufacturer with good product quality and suitable stainless steel screws.
