In the realm of stainless steel, there exists a variant that shines with the brilliance of a mirror, a material that finds its place in industries demanding high brightness, such as decoration and optics. This is the Mirror 8K stainless steel coil, a product that combines aesthetic appeal with practical functionality. Its vibrant surface and high corrosion resistance make it an ideal choice for wallboards and a myriad of other applications. Let's delve deeper into the world of Mirror 8K stainless steel coil.
What is Mirror 8K Stainless Steel Coil?
Mirror 8K stainless steel is a product of meticulous mechanical grinding and polishing of BA, 2B, or matte stainless steel surfaces. This process transforms the steel into a material with a surface as bright as a mirror, capable of reflecting objects. The polished steel is then rolled to form the Mirror 8K stainless steel coil.
The terms 'mirror' and '8K' in Mirror 8K stainless steel have specific meanings. 'Mirror' signifies a treatment standard for stainless steel surfaces, achieved through polishing and grinding. '8K', on the other hand, refers to the alloy proportion and reflectivity grade of the processed stainless steel. The '8' denotes the alloy proportion, while 'K' represents the mirror grade.
Mirror 8K stainless steel comes in two types: single-sided and double-sided. The difference lies in the polishing process, with the double-sided variant requiring more time and cost due to the additional polishing on the other side.
The Mirror Grade of Mirror 8K Stainless Steel Coil
The mirror grade of stainless steel varies, with options including 6K, 10K, and 12K. The larger the number, the finer the mirror:
- 6K refers to a rough grinding and polishing mirror panel, slightly less effective than a mirror.
- 10K denotes a finely ground and polished mirror panel, similar in reflectance to an ordinary mirror.
- 12K signifies an ultra-fine grinding and polishing mirror panel, suitable for optical applications.
However, this grading standard is not uniform. As long as the brightness is greater, the reflectivity is higher, and surface defects are fewer, the stainless steel is considered equivalent to 8K stainless steel.

The Production Process of Mirror 8K Stainless Steel Coil
The production of Mirror 8K stainless steel coil involves a series of steps, starting with the basic plates, which are mostly 2B and BA. The process requires a grinding liquid, a mixture of water, nitric acid, and iron-red powder in a specific ratio. The better the ratio, the higher the quality of the product.
-
Rough Polishing: This step involves grinding the stainless steel from coarse to fine using six sets of grinders. This process removes surface defects such as roughness, burrs, and trachoma.
-
Fine Polishing: High-density wool felt and slurry are used in this step to remove the oxide layer, sand marks, and grinding headlines on the stainless steel surface, thereby improving its luminosity.
-
Washing and Drying: After polishing, the stainless steel surface is cleaned with a brush dipped in clean water, followed by drying using a baking lamp.
-
Quality Inspection: The processed stainless steel is checked for breadth, blisters, dark bones, scratches, deformation, and whether the grinding head is within the standard range.
-
Packing with Protective Film: The finished Mirror 8K stainless steel is covered with a protective film and packed in a box.
The production process for double-sided Mirror 8K stainless steel coil is similar, but it requires additional steps to prevent scratches on the other side and to replace the protective film after polishing the second side.

Colouring the Mirror 8K Stainless Steel Coil
Mirror 8K stainless steel coil can also be coloured using various methods:
- Plating: An electrolyte is used to attach a metal film to the surface of the coloured stainless steel, improving corrosion resistance, abrasion resistance, conductivity, light reflection, and aesthetics.
- Water Plating: The stainless steel is placed in an aqueous solution, causing ions on the surface to form a metal coating.
- Fluorocarbon Paint: In this process, fluororesin is the main film-forming substance.
- Spray Paint: Paint is sprayed on the stainless steel plate in the form of mist, resulting in different colours.
Features and Applications of Mirror 8K Stainless Steel Coil
Mirror 8K stainless steel coil boasts good corrosion resistance and thermal fatigue. However, its resistance to inter-granular corrosion is not as good as the 200 series stainless steel. It is often used as a substitute for the 200 series stainless steel.
Compared to the 304 material, Mirror 8K stainless steel has lower tensile properties, welding properties, and thermal expansion, making it relatively cheaper and widely used. It is also magnetic and highly durable.
Mirror 8K stainless steel coil is primarily used in various decoration or metal optical products. It is also suitable for cabinet decoration and architectural applications due to its aesthetic appeal and durability.

The Future of Mirror 8K Stainless Steel
The future of Mirror 8K stainless steel looks promising. Its beautiful colour, good corrosion resistance, and equipment properties make it a sought-after decoration material. The colour surface layer of Mirror 8K stainless steel coil can withstand high temperatures of up to 200 degrees and does not fade for a long time. The colour changes with the angle of light, adding to its aesthetic appeal.
In the future, Mirror 8K stainless steel can be used for decorating hall wall panels, ceiling elevator car panels, car box panels, architectural decorations, signboards, and more. It is also very suitable for wall decoration.
Conclusion
Mirror 8K stainless steel coil is a product of meticulous mechanical grinding and polishing of BA, 2B, or matte stainless steel surfaces. It is a material that combines aesthetic appeal with practical functionality, making it a popular choice in various industries. With its good corrosion resistance, heat fatigue resistance, tensile properties, and welding properties, Mirror 8K stainless steel coil is not only relatively cheap but also widely used. Its future looks promising, with potential applications in various decoration or metal optical products.
