How to prevent stainless steel from rusting
The first one: that is to directly use anti-rust oil for anti-rust, that is, the so-called oil film anti-rust, and it is called physical anti-rust.
The second: that is the so-called chemical anti-rust method, which is the stainless steel passivation anti-rust that is often used by customers. The anti-rust agent is a metal anti-rust, and it is called the chemical passivation anti-rust method. It is completely different from the principle of physical antirust. The principle of physical anti-rust is to isolate the surface of stainless steel from the air so as not to be oxidized, while the stainless steel passivation solution is in contact with the surface of the workpiece to produce a chemical reaction, transforming the chromium-poor layer of stainless steel into a chromium-rich layer so that The workpiece achieves the anti-rust effect of high salt spray, which is dozens of times stronger than traditional anti-rust oil, and the surface is clean and fresh.
