Grade, size, and surface treatment can be customized according to needs
A 304 stainless steel sheet with 8 mirror finish is a highly reflective, polished sheet known for its exceptional smoothness and shiny appearance. The #8 mirror finish is achieved through a multi-step polishing process that creates a non-directional, mirror-like surface.
Mirror finish is also called 8K, No.8, and polish finish, which is the most reflective mirror finish with high quality to similar as a glass mirror. The final surface is blemish-free with high image clarity and is the true mirror finish.

304 stainless steel sheet 8 mirror process
Polishing Process of 304 Stainless Steel Plate
304 stainless steel plates can achieve a mirror-like finish through either electrolytic or mechanical polishing methods:
- Electrolytic Polishing:
This process uses electrochemical principles to polish the stainless steel surface in a specific electrolyte, resulting in a smooth, mirror-like effect.
- Mechanical Polishing:
In this method, mechanical equipment grinds and polishes the stainless steel surface, also producing a mirror-like finish.
Process Flow (Electrolytic Polishing Example):
The electrolytic polishing process typically follows these steps:
- Degreasing: Removes oil and grease from the surface.
- Soaking: Prepares the surface for polishing.
- Electrolytic Polishing: Polishes the surface using an electrochemical reaction.
- Soaking (again): Further cleans the surface after polishing.
- Stripping (optional): Removes any unwanted layers.
- Neutralization: Neutralizes residual chemicals.
- Pure Water Rinse: Ensures a clean surface.
- Drying and Packaging: Prepares the stainless steel plate for storage or shipping.
These steps remove surface oils and impurities, forming a uniform, smooth oxide film that creates a high-gloss, mirror-like finish.
