Hexagon screw manufacturers show you what is metal corrosion?

With the rapid development of the times, there are more and more things people can't live without, such as our smartphones and the Internet. And metal has become one of the widely used materials in contemporary society, it is as large as cars, ships, rockets, as small as a small screw. The common problems with metals are corrosion, fracture and wear, and today we are talking about metal corrosion.

Metal corrosion can be divided into general corrosion and local corrosion. Comprehensive corrosion is also called uniform corrosion. It refers to the distribution of corrosion phenomena in different degrees, which can be uniform or uneven. This kind of corrosion is less harmful and often appears in steel materials in the atmosphere and sea water.

Localized corrosion, also known as non-uniform corrosion. According to the data, local corrosion accounts for 80% of the industry, and local corrosion is concentrated in one location, and the material will be eroded quickly. This kind of corrosion is very harmful and can easily cause sudden disasters. In order to avoid the corrosion of screws, customers will be advised to do passivation treatment, which can extend the service life of screws.
