Screw anti-corrosion technology

Stainless steel screw is made by metal and metal corrosion method mainly has four aspects, namely the nature of the material itself, the use of environment, data and environment of the interface, and improve the metal structure design, with a complete corrosion of the alloy to produce stainless steel screws, unless there are special requirements, or in terms of the concept of uneconomical in economy, the appearance of the screw corrosion environment factor is the complete isolation is unrealistic. Improved metal structure design can be in a certain situation to improve the impact of special circumstances, but most of the design of stainless steel screws can not be fully modified, and its maintenance role is not eternal, so this method can not be basic treatment, as long as the surface corrosion prevention, that is, the appearance corrosion treatment is the most widely used method.

Stainless steel screw surface corrosion treatment is the use of a variety of methods in the metal appearance of the maintenance layer, its role is to isolate the metal and corrosive environment, in order to inhibit the corrosion process, or reduce the corrosive medium and metal surface contact, so as to avoid or reduce the purpose of corrosion.
