Several situations in which colored stainless steel plates will be corroded

In recent years, colored stainless steel plates can be said to be a new star in the decoration industry. They are widely favored by customers for their beautiful colors, excellent anti-corrosion, and easy processing. But do you know? Colored stainless steel plates can also cause corrosion if used improperly, which is not necessarily a quality problem with the plates.

The use environment is the primary reason: if it is in a relatively humid coastal area, colored stainless steel plate products exposed outdoors are most susceptible to chronic corrosion. Because sea water evaporates, humid air and rainwater carrying a relatively large amount of salt cover the surface of the plate, and galvanic corrosion occurs. This corrosion process is relatively slow due to the relatively weak environment and is generally not easy to detect. But over time, it will cause damage to the surface of the board.

There are also big reasons for the choice of material: the most common colored stainless steel plate products on the market are made of 201 or 304. Due to the difference in nickel content, the anti-corrosion performance of 304 stainless steel plates is much higher than that of 201 stainless steel plates. Therefore, if it is used indoors, you can consider the cheaper 201 stainless steel plates, but for outdoor use, 304 stainless steel plates are preferred. .

Human reasons also exist: some detergent products may be used during the cleaning process. Today's cleaning agents may be more or less weakly acidic or weakly alkaline. Since these cleaning agents remain on the surface of the colored stainless steel plate and are left in this environment for a long time, the surface of the colored stainless steel plate will be chronically corroded. Therefore, in daily cleaning, just wipe it with a soft cloth dipped in water. Try not to use strong detergents with chemical ingredients. If you use detergent, be sure to remove the remaining stains.
