Rust prevention of stainless steel flanges

The rust prevention method of stainless steel flange is very simple, there are two rust prevention methods:

The first one: that is to directly use anti-rust oil to prevent 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 rust prevention method, which is the passivation and rust prevention of stainless steel flanges that are often used by customers now. , which is completely different from the principle of physical rust prevention. The principle of physical rust prevention is to isolate the surface of the stainless steel flange from the air so as not to be oxidized, while the stainless steel passivation is to produce a chemical reaction by contacting the stainless steel passivation liquid with the surface of the workpiece, and to convert the chromium-poor layer of the stainless steel into a chromium-rich layer. The workpiece can achieve anti-rust effect, which is dozens of times stronger than traditional anti-rust oil, and the surface is clean and refreshing.
