The stainless steel mirror sheet is made of stainless steel plate by professional polishing equipment.
It is commonly used in various high-end products and decorative materials.
There are different grades of stainless steel mirrors.

What does 8K mean and what do other grades represent?
Stainless steel mirror sheet is used to polish the stainless steel plate on the initial surface such as 2B or No.1 into a mirror surface (scientific name: 8K mirror or No.8), which is used for luxurious decoration of hotels, shopping malls, clubs, bars, KTVs, display cabinets, etc., and can be used for decoration of hall wallboards, ceilings, elevator sheets, trunk boards, signs, etc.
The surface polishing of stainless steel materials can make the stainless steel surface bright and clear.
The mirror stainless steel surface can be divided into 6k, 8k, etc. according to the grade.
The higher the grade, the higher the brightness, and the less defects allowed on the surface.
The mirror stainless steel plate is usually called “mirror” only when its surface roughness value Ra ≤ 0.05um and surface finish is greater than 10.
8K mirror stainless steel plate is the base plate for processing subsequent color plates or etched plates, which is mainly used for various decoration or metal optical products.
The literal meaning of 8K: the corrosion resistance of stainless steel white steel depends on its alloy composition (inscription, nickel, titanium, silicon, manganese, etc.
The “8” in 8K refers to the proportion of alloy components (304 stainless steel mainly refers to the content of elements),
“K” refers to the grade of reflectivity after polishing.
8K mirror surface is the mirror surface grade reflected by chrome nickel alloy steel.
The common mirror stainless steel is also extended to 6K, 10K, 12K, etc. due to the different degrees of fineness required by customers, and the larger the “definition” is, the higher the fineness of its mirror.
6K refers to the mirror sheet with rough grinding and polishing, which is less effective than the mirror;
10K refers to the fine grinding and polishing mirror sheet, which is comparable to ordinary mirrors;
12K refers to ultra-fine grinding and polishing mirror sheet, which can meet optical purposes.
However, there is no uniform standard for the mirror sheet of any steel type at any level.
The higher the brightness, the greater the reflectivity, and the fewer surface defects (white spots/pinholes/silk lines), the better the mirror effect.
