What is 8K stainless steel?
The stainless steel mirror panel is polished to be similar to the mirror surface (scientific name: 8K mirror or No.8) by mirror polishing method ba, 2b or No.1.
Definition of 8K mirror surface: stainless steel surface after grinding and polishing, the appearance is bright as a mirror, reflecting people, commonly known as mirror 8K, which has corrosion resistance; and mirror plate is the substrate for processing subsequent color or etching plate. It is mainly used in all kinds of decoration 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 its internal structure. Among them, chromium plays a decisive role. It can form a passivation film on the surface of the steel, which can block the metal from the outside without oxidation and enhance the corrosion resistance of the steel plate. The "8" in 8K refers to the content of alloy (304 stainless steel mainly refers to the content of nickel), and "K" refers to the level of reflectivity after polishing (Grade K is the specular reflection grade). 8K mirror is also the mirror grade of chromium nickel alloy steel.
The common mirror stainless steel is also extended to 6K, 10K, 12K, etc. due to the different fineness required by customers, and it is "defined" that the larger the number, the higher the fineness of the mirror. 6K refers to the mirror panel with rough grinding and polishing, whose efficiency is a little worse than that of mirror; 10K refers to fine grinding and polishing mirror panel, which can compare with general mirror; and 12K refers to ultra-fine grinding and polishing mirror panel, which can satisfy optical application.
However, there is no consistent standard for the mirror panel of any kind and steel grade. The higher the brightness, the greater the reflectivity, and the less appearance defects (white spots, pinholes, orange peel lines, water ripple, etc.), the more recognized by customers. In fact, this is a strategy that the market puts forward to satisfy people's desire in response to people's higher expectations for demand, and it is not of great practical significance. Similarly, high brightness can be collectively referred to as 8K.

What are the functional features of stainless steel plate?
Analysis of functional characteristics of stainless steel plate: 1. Corrosion resistant stainless steel plate has similar ability to resist general corrosion as unstable NiCr 304. Long time heating in the temperature scale of chromium carbide may affect the corrosion resistance of alloys 321 and 347 in harsh corrosive media. It is mainly used at high temperature, which requires strong sensitization resistance to prevent intergranular corrosion at lower temperature. 2. High temperature oxidation

Four factors affecting the coating of stainless steel plate
There are four kinds of factors that affect the coating of stainless steel plate: first, the connotative factor of stainless steel plate. What we all know is that the low nickel content in stainless steel makes the passivation function of stainless steel low. Therefore, the content of martensite and chromium and nickel in stainless steel has great influence on the passivation function of stainless steel plate. Second, stainless steel plate uses the medium in the environment. In thermodynamics, t

What are the materials that cannot be cut by fiber laser cutting machine?
People who have a certain understanding of the fiber laser cutting machine should know that its use scale is very wide, and the cutting effect is also very good. But fiber laser cutting machine is not what kind of material can be cut, there are some materials on the fiber laser cutting machine damage is relatively large, so can not use the fiber laser cutting machine to cut. Although the fiber laser cutting machine has many excellent characteristics, it is not invincible. There are still many da

What kinds of laser cutting machines are there?
According to the different laser generators, laser cutting machines on the market can be roughly divided into three types: CO2 laser cutting machine, YAG (solid state) laser cutting machine and optical fiber laser cutting machine. One: CO2 laser cutting machine, CO2 laser cutting machine can stably cut carbon steel within 20 mm, stainless steel within 10 mm, and aluminum alloy below 8 mm. The wavelength of CO2 laser is 10.6um, which is easy to be absorbed by nonmetallic materials. It can cut woo
