Stainless Mirror Processing
Stainless steel surface processing is more common in stainless steel processing, usually wire drawing, mirror surface and so on.
Among them, the stainless mirror panel is a very common metal decoration material, and we can often see it in public places or large entertainment facilities.
However, the stainless mirror products processed and sold on the market are different due to various reasons, and the effects of processing into mirrors are uneven.
So, what is the cause of such “chaos”?
Stainless steel mirror plates are commonly known as “8K”. The “8” in “8K” refers to the proportion of alloy components (304 stainless steel mainly refers to the content of nickel), and “K” refers to the reflectance achieved after polishing The grade (K grade is the specular reflection grade). 8K mirror is the mirror grade embodied in chromium-nickel alloy steel.
Common mirror stainless steels have been extended to 6K, 10K, 12K, etc. due to the difference in the degree of fineness required by customers, and the greater the defined number, the higher the fineness of the mirror surface. 6K refers to the rough grinding and polishing mirror panel, which has a slightly worse effect than mirrors; 10K refers to the fine grinding and polishing mirror panel, which can be comparable to ordinary mirrors; and 12K refers to the ultra-fine grinding and polishing mirror panel, which can meet optical applications.
Normally, the stainless steel on the BA surface that has been brightly annealed and the 2B surface of the passivation treated is processed to remove the oxide layer on the surface of the stainless steel, revealing the original bright and clean “natural color” of the metal, which can be called a mirror surface. At present, stainless steel processing mirrors mainly use three methods: electrolytic polishing, chemical polishing, and mechanical grinding and polishing; although the first two methods are effective, they are costly and inefficient. Although the effect of mechanical grinding and polishing is slightly worse than the previous two methods, its convenience and high efficiency have become the first choice for stainless steel mirror processing.
