Method for prolonging service life of 304 stainless steel plate

With the development trend of social economy, 304 stainless steel plate is more and more widely used. Everyone is closely related to 304 stainless steel plate commodities in daily life, but many people know little about the characteristics of 304 stainless steel plate and think 304 stainless steel plate is not raw embroidery.

In fact, the corrosion resistance of 304 stainless steel plate is very good. Due to a layer of purification treatment film on the surface, it exists in a more stable way of metal oxide in nature. However, 304 stainless steel plate is based on the application standard, and the air oxidation level is also different, but it will be oxidized. This situation is usually called etching.

304 stainless steel plate product is a position with poor corrosion resistance of purification treatment film in appearance design, because exposed to the etching natural environment, the metal surface produces photocatalysis or chemical changes, resulting in galvanic corrosion imagination and small round holes. Combined with the closed type of aerobic ions, it forms a strong corrosion saturated solution to speed up the etching reaction rate.

In order to better increase the service life of 304 stainless steel plate, the following aspects are summarized in the categories and countermeasures that 304 stainless steel plate is likely to be etched by 100 plating needles:

1. Cleaning method

When cleaning the appearance of 304 stainless steel plate, you must pay attention not to attack the scratch of the appearance. Avoid using bleach, coarse wax, steel ball and special tools for grinding to remove the detergent. After cleaning the appearance, clean it with tap water.

2. How to deal with dust

The appearance of 304 stainless steel plate contains dust and stains that are easy to eliminate. It can be cleaned with detergent composed of soap, weak detergent and adhesive, and cleaned with ethanol or organic solution (medical ether and benzene).

3. Lubricating grease

The surface of 304 stainless steel plate has vegetable grease, which is oily and clean without oil stain. Clean it with soft rag, neutral detergent or ammonia solution or special detergent.

4. Acid etching

304 stainless steel plate has bleach and various acid-base accessories. It shall be cleaned immediately with clean water, then soaked with ammonia solution or neutral sodium carbonate solution, and cleaned with neutral detergent or warm boiled water.

5. Seven color rainbow pattern appearance

The appearance of 304 stainless steel plate has rainbow pattern. If there is too much detergent or oil, it can be washed off with warm boiled water and neutral detergent.

6. Stick rust

The rust caused by the stain on the surface of 304 stainless steel plate can be cleaned with 10% sodium cyanide or crude wax or special detergent.
