With the improvement of people’s living standards, 304 stainless steel is being used more and more widely, and there are more and more manufacturers of 304 stainless steel. Of course, there will inevitably be mixed with bad quality, which is very important to customers. It is said that how to choose has become a big headache. 304 stainless steel has a smooth surface, high plasticity, toughness and mechanical strength, and is resistant to corrosion by acid, alkaline gas, solution and other media. It is an alloy steel that does not rust easily, but not rust-free. 304 stainless steel plate refers to a steel plate that is resistant to corrosion by weak media such as atmosphere, steam and water, while acid-resistant steel plate refers to a steel plate that is resistant to chemical corrosive media such as acid, alkali, and salt. The following 304 stainless steel plate manufacturers will teach you how to distinguish the quality of stainless steel plates?
1. There should be no scratches on the surface of the stainless steel plate. This is a more critical point that directly affects the quality of the stainless steel mirror panel. If there are scratches on the stainless steel raw material 2B board, the slight ones can be eliminated in the process of grinding the mirror surface (8K), and the deeper scratches cannot be eliminated. If the scratches are left after grinding the mirror surface, there is no way to eliminate them. Generally speaking, the newly left scratches are caused by the workers not paying attention to the operation process during the operation, and the scratched lines are new And the surface of the scratch is relatively sharp, while the scratch on the plate is relatively smooth after grinding the mirror surface.
2. There should be no trachoma on the surface of 304 stainless steel. Trachoma is a small hole that can be seen with the naked eye on the panel. This is also a very important point. The occurrence of trachoma has a lot to do with the raw material.
3. The 304 stainless steel plate cannot have the grinding head pattern. The grinding head pattern is circle after circle, which is the mark left by the 8K machine grinding head and the equipment not in good contact.
4. The 304 stainless steel plate cannot have roller prints. This is left by the rollers of the 8K machine, which are rows of roller prints.
