201: A commonly used austenitic stainless steel with good corrosion
resistance and moderate strength.
203: There isn't a widely recognized stainless steel grade called
"203." It is possible that it refers to a specific proprietary or
less common grade.
304: A popular austenitic stainless steel grade known for its
excellent corrosion resistance, versatility, and ease of
fabrication.
316: An austenitic stainless steel grade that contains molybdenum,
which enhances its corrosion resistance, particularly against
chlorides and acids.
316L: A low-carbon version of 316 stainless steel, providing
improved weldability and resistance to sensitization (carbide
precipitation during welding).
304L: Similar to 316L, it is a low-carbon version of 304 stainless
steel, offering better weldability and corrosion resistance in
certain environments.
904: Refers to a specific stainless steel grade known as 904L,
which has high corrosion resistance, especially against strong
acids like sulfuric acid.
Surface Finishes:
2B: A smooth, semi-reflective finish obtained through a
cold-rolling process, followed by annealing and descaling.
BA: Stands for "bright annealed." It is a highly reflective,
mirror-like finish achieved by annealing in a controlled atmosphere
furnace.
No.4: Also known as a brushed or satin finish, it has a
unidirectional texture obtained by mechanical polishing.
8K: A high-gloss, mirror-like finish achieved through an extensive
polishing process.
4x8 Size: Refers to the standard size of the stainless steel sheet,
which is 4 feet by 8 feet (approximately 1.2 meters by 2.4 meters).
Cold Rolled: Indicates that the stainless steel sheet was produced
through a cold rolling process, which involves passing the metal
through rollers at room temperature to reduce thickness and improve
surface finish.
In summary, the information you provided describes various
stainless steel grades (201, 203, 304, 316, 316L, 304L, 904) with
different surface finishes (2B, BA, No.4, 8K). The stainless steel
sheets are cold-rolled and have a standard size of 4x8 feet.
Prodcut Name | Stainless steel sheet/plate |

| Surface Treatment Method | Description |
|---|---|
| Mirror Polishing | Achieves a highly reflective mirror finish on the stainless steel surface through mechanical or chemical methods. |
| Electrolytic Polishing | Removes rough portions of the stainless steel surface through an electrolytic process in an electrolyte solution, resulting in a smoother surface. |
| Sandblasting | Uses high-pressure air or a sandblasting machine to project abrasive particles onto the stainless steel surface, removing stains and creating a rough surface texture. |
| Chemical Etching | Treats the stainless steel surface with a chemical solution to achieve specific textures or decorative effects. |
| Passivation | Forms a protective oxide film on the stainless steel surface to enhance its corrosion resistance. |
| Coating/Painting | Applies a layer of paint or coating on the stainless steel surface to enhance both decorative and protective properties. |
| Vaporizing | Creates a fine particle texture on the stainless steel surface through specialized spraying techniques, resulting in a unique tactile and visual appearance. |
| Brushing | Mechanical treatment of the stainless steel surface using brushing or rolling tools to create uniform scratch patterns. |
Stainless steel surfaces can be classified into various categories, each with different characteristics and applications. Here are some common classifications of stainless steel surface finishes and their distinguishing features and applications:
Bright finishes:
Rough finishes:
Corrosion-resistant treatments:
Decorative treatments:
