The bright surface means that the stainless steel is very bright, and the common specular gloss stainless steel is divided into three types: 6K, 8K, and 10K. The bright surface does not refer to the specific, relatively speaking, the requirement is relatively low, that is to say, as long as there is brightness, it can be referred to as 6K.
The mirror surface refers to the surface state of stainless steel. The mirror surface is an 8K surface in the industry.
Double mirror stainless steel, as its name suggests, is a stainless steel mirror on both sides. Double-sided stainless steel is much more difficult than single-sided stainless steel.
Common mirror stainless steel is divided into three types: 6K, 8K, and 10K. Generally it is ordinary polishing, ordinary 8K, fine grinding 8K, super fine grinding 10K effect. The same thickness is generally not much different, the 10K mirror is brighter; the thicker the thickness, the worse the effect and the higher the processing cost. At present, the most high-end mirror effect is the effect of hand grinding more than 12K.
The stainless steel mirror panel is polished by mirror polishing to a stainless steel plate of the initial surface such as BA, 2B or No. 1 to resemble a mirror surface (scientific name 8K mirror or No. 8).
8K mirror definition: stainless steel surface polished and polished, the surface is bright as a mirror, according to the object, commonly known as mirror 8K, it has corrosion resistance; and mirror plate is the substrate for processing subsequent color or etching plate. Mainly used in various decorative or metal optical products.
The literal definition of 8K: the corrosion resistance of stainless steel white steel depends on its alloy composition (chromium, nickel, titanium, silicon, manganese, etc.) and the internal structure, which plays a decisive role in chromium, which can be on the surface of steel. The passivation film is formed so that the metal is isolated from the outside without oxidation, and the corrosion resistance of the steel sheet is enhanced. The “8” in 8K refers to the proportion of the alloy containing components (304 stainless steel mainly refers to the content of nickel), and “K” refers to the grade achieved by the reflectance after polishing (K grade is the specular reflection grade). ). The 8K mirror is also the mirror grade of chrome-nickel alloy steel.
Common mirror stainless steels have been introduced to 6K, 10K, 12K, etc. due to the different degree of fineness required by customers, and the larger the number is defined, the higher the fineness of the mirror. 6K refers to the rough-polished mirror panel, which is slightly worse than the mirror; 10K refers to the fine-polished polished mirror panel, which can be compared with ordinary mirrors; and 12K refers to the ultra-fine grinding and polishing mirror panel, which can meet optical applications.
But no matter what level, which steel mirror panel has not yet had a uniform standard, the higher the brightness, the greater the reflectivity, the more surface defects (white spots, pinholes, orange peel, water ripples, etc.) Less, the more you can be recognized by customers. In fact, this is a strategy that satisfies people’s wishes in response to the market’s expectation of a higher demand for demand, and does not have much practical significance. The same high brightness can be collectively referred to as 8K.
