First of all, we need to know that stainless steel mirror sheet is through a mirror polishing technology to polish the initial surface of the BA, 2B or NO.1 stainless steel sheet into a mirror-like surface, its scientific name is 8K mirror or NO.8.
The definition of 8K mirror sheet is: the surface of stainless steel plate after grinding and polishing process, the surface can be bright as a mirror, reflecting the object, which is commonly known as the mirror 8K plate. 8K mirror sheet has corrosion resistance, and mirror sheet can also be color plating and etching process, mainly used in various types of decoration or metal optical products.
8K literal definition: the corrosion resistance of stainless steel sheet is mainly dependent on its alloy composition (chromium, nickel, titanium, silicon and manganese, etc.) and internal structure, which plays a decisive role is the chromium element, which can form a passivation film on the surface of the steel, so that the metal and the outside world to produce isolation and thus play a role in preventing oxidation, to enhance the corrosion resistance of stainless steel plate. 8K mirror stainless steel sheet in the "8" refers to the proportion of alloy components, to 304 stainless steel plate, for example, the "8" worth is the content of nickel; and "K" It refers to the stainless steel sheet after polishing process of the reflectivity can reach the level (K level is the level of mirror reflection), so 8K mirror sheet is also the chromium-nickel alloy embodied in the grade of mirror.
