As the name suggests, the stainless steel plate gives the impression that it will not rust. So once there is a rust problem, it is a serious quality problem, but there is no lack of sparseness. The use environment of the stainless steel plate will seriously affect the composition of the material, making The corrosion resistance of stainless steel decreases, and rust will occur. There are many kinds of stainless steel rust, some are slight water rust, some are rust spots with dots, and some are large areas of rust, etc., then how to determine what causes the occurrence of What are the symptoms of rust? How to prevent stainless steel from rusting?
Generally speaking, the occurrence of rust is due to the fact that the board is wetted by rain during transportation and delivery, and then the rain penetrates into the packaging bag, causing part of the rust phenomenon. For this kind of similar rust, you can directly use the anti-rust paste to apply it for maintenance, no matter about the quality of the material itself.
And for the rust spots of the dots, most of them are due to the impact of environmental problems. For wet and dark environments, the corrosion resistance and oil resistance of stainless steel plates are reduced. For example, the use of 201 stainless steel on the river is prone to spot-like rust spots, and the spot rust may become larger and larger.
Large areas of rust are produced. After investigation by technical personnel in the industry, it is possible to determine the cause, and the occurrence of quality problems cannot be ruled out. The peeling of the surface of the raw material or the trachoma phenomenon of the board surface, which can easily cause the surface of the board to rust.
Therefore, when you buy stainless steel plates, try to choose branded stainless steel plates, and let the supplier provide a genuine quality guarantee, so as to ensure the stable quality of the stainless steel plate.
What should we do if the stainless steel rusts?
First, the use environment of stainless steel is required, and it needs to be wiped frequently to remove dust and keep it clean and dry.
Second, the hot nitric acid concentration can be 30-40%, and it can be cleaned with clean water about 5 minutes after brushing.
Three, if the area is not large and the corrosion is not serious, you can try it with wujie powder, it is easy to use. Slightly corroded, if you are afraid of rubbing, you can wipe it with a soft cloth and toothpaste, and it can also play a polishing role.
Fourth, many unscrupulous dealers are sub-charged. You want 304 to give you 201. You want 316 to give you 304 (somewhat moral), or even 201. It is recommended that you go to a test and do a spectrum to understand. If you find counterfeit goods, you should actively protect their rights.
