Influencing factors of 304L stainless steel coil
Some people think that the brighter the surface and the higher the purity of the 304L antibacterial stainless steel coil, the better its quality. In fact, this is a misconception, the purity and chroma of 304L antibacterial stainless steel coil have nothing to do with each other. At present, there are many technologies that can change the color of the surface of antibacterial stainless steel, and the polishing technology is very good now, but polishing does not mean that the composition of antibacterial stainless steel will change.
In the production process, many different metal elements will be added to finally become 304L antibacterial stainless steel, so what is the basis for distinguishing the quality of 304L antibacterial stainless steel coil? In fact, the purity of 304L antibacterial stainless steel coil is not the same as Quality, on the contrary, is judged by the content of various chemical molecules in the production process. For example, in the national standard, the chromium content contained in 304L antibacterial stainless steel coil is 18~20%, and the antibacterial stainless steel has relatively strong compressive strength, wear resistance and ductility. The nickel content in 304L antibacterial stainless steel coil is 8~12%, and the increase of the proportion improves the corrosion resistance of the antibacterial stainless steel. The carbon content of 304L antibacterial stainless steel coil is extremely low, less than 0.03%, so 304L antibacterial stainless steel has the ability to resist stress corrosion. Therefore, if you need to distinguish the quality of 304L antibacterial stainless steel coil, you can look at the ingredients it contains.
How to store 304L stainless steel coil
1. When storing, use wooden sticks to separate from the ground to avoid scratches on the surface.
2. When storing, pay attention to moisture, dust, oil, lubricating oil, etc., to avoid long-term storage in such an environment that may cause surface rust or other performance degradation.
3. 304L stainless steel coils should be stored in a clean, dry, and ventilated place, and the original packaging should be kept, and the packaging should not be easily opened.
4. The 304 stainless steel coil with film should be protected from direct light. If the film deteriorates during storage, it should be replaced immediately.
5. If the backing paper is soaked, the backing paper should be removed immediately to prevent surface corrosion.
Advantages of 304L Stainless Steel Coil
The advantage of 304L stainless steel coil is that it is high quality and low price. You can freely customize the length and width of the stainless steel open plate, but the thickness is set at the factory and cannot be changed; it is convenient for transportation, and you don’t have to worry about the size of the 304L stainless steel coil being too large to fit. ;Some metal product processing factories determine the size of 304L stainless steel coils according to practical needs, which can effectively save resources and reduce costs.
Disadvantages of 304L stainless steel coil
304L stainless steel coils have a high degree of internal stress and thus poor dimensional stability. With the different process parameters of Kaiping operation, the distribution of internal stress is also different, showing different directions of vertical length and different bearing capacity. Moreover, this carrying capacity is difficult to weigh with the strength standard. Therefore, the 304L stainless steel coil will have a large welding deformation during welding, and the adjustment is difficult. Therefore, the 304L stainless steel coil cannot be used for workpieces that require high appearance quality.
