Application ：

Architecture and Construction: Mirror stainless steel sheets are used in architecture and construction for interior and exterior design elements such as wall panels, cladding, elevator doors, and column covers.

Automotive and Aerospace: Mirror stainless steel sheets are used in the automotive and aerospace industries for various applications, including trim and decorative accents, exhaust systems, and engine components.

Food and Beverage: Mirror stainless steel sheets are used in the food and beverage industry for equipment such as countertops, sinks, and food processing equipment due to their easy maintenance, corrosion resistance, and hygienic properties.

Medical and Pharmaceutical: Mirror stainless steel sheets are used in the medical and pharmaceutical industries for applications such as clean rooms, medical instruments, and laboratory equipment due to their easy maintenance, corrosion resistance, and hygienic properties.

Art and Decor: Mirror stainless steel sheets are used for artistic and decorative purposes, such as sculptures, art installations, and furniture, due to their reflective and aesthetically pleasing surface finish.

Electronics and Technology: Mirror stainless steel sheets are used in the electronics and technology industry for applications such as computer and mobile device casings, as well as for decorative purposes in home electronics.

Q1. What is a mirror stainless steel plate?

A1:Definition: Stainless steel plates with mirror effects after polishing are professionally called "8K plates". They are divided into three grades: 6K (ordinary polishing), 8K (fine grinding), and 10K (super fine grinding). The higher the value, the better the brightness.
Material: Commonly used 304 and 316 stainless steel (strong corrosion resistance), 201, 301, etc., the base material needs to use 2B/BA surface (smooth surface without defects) to ensure the mirror effect.

Q2. What are the size specifications of mirror stainless steel plates?
A2:Conventional size:
Thickness 0.5-3mm: width 1m/1.2m/1.5m, length 2m-4.5m;
Thickness 3-14mm: width 1.5m-2m, length 3m-6m5.
Extreme size: Maximum width can reach 2m, length can reach 8-12m (limited by processing equipment, the cost and risk of super long plates are higher).

Q3. What are the key processes of mirror processing?
A3:Process:
Sandblast the substrate to remove the oxide layer.
Grind with 8 sets of coarse and fine grinding heads (coarse sandpaper determines brightness, fine felt controls grinding head flower);
Wash → dry → apply protective film.
Quality points: The slower the travel speed and the more grinding groups, the better the mirror effect; surface defects of the substrate (such as sand holes) will directly affect the quality of the finished product.

Q4. How to deal with surface scratches?
A4:Minor scratches: Manual polishing and repair with polishing wax (mirror surface), or repair with a wire
drawing machine (wire drawing surface).
Deep scratches:
Point scratches: TIG welding, repair welding → grinding → re-polishing
Linear/large area scratches: Need to return to the factory to lower the grinding head and reduce the speed of grinding. Deep scratches may not be completely repaired
Preventive measures: Apply 7C thickened protective film, and use wooden frames + waterproof paper to pack during transportation to avoid contact with hard objects.

Q5. Why may the corrosion resistance of mirror stainless steel be reduced?
A5:Chloride ion corrosion:
destroys the passivation film, avoid contact with chlorine-containing environments (such as swimming pools, salt spray environments), and clean regularly.
Insufficient surface cleanliness: residual acid or stains will accelerate corrosion, and thorough cleaning and passivation are required after processing.
Material factors:
low nickel (such as 201) or martensitic structure stainless steel has weak passivation performance, and 304/316 materials are recommended.

Q6. How to inspect the quality of mirror stainless steel plates?
A6:Visual inspection: tear off the four corners of the protective film and check whether there are sand holes (pinholes), grinding head flowers (hair-like lines), and peeling (white lines).
Thickness tolerance: allowable error ±0.01mm (1 wire), exceeding the tolerance may be inferior products. Film layer requirements:
high-quality boards with 7C or above thickened laser film to prevent transportation scratches.
