| Term / Finish | Description |
| No. 1 | A hot-rolled, annealed, and descaled finish, typically rough and dull. It's commonly used for industrial applications where the finish isn't a primary concern. |
| No. 2D | A dull finish produced by cold rolling, annealing, and descaling. May be used for deep-drawn parts or those where a glossy finish isn't necessary. |
| No. 2B | A smooth, moderately reflective cold-rolled annealed and pickled or descaled finish. A standard finish for most stainless steel appliances and for sheet metalwork. |
| No. 3 | An intermediate polished finish obtained with approximately 100-grit abrasive, typically used where a semipolished finish is required. |
| No. 4 | A general-purpose polished finish, typically obtained with a 150-180 grit abrasive. Common in kitchen appliances and elevator panels. |
| No. 6 | A soft satin finish having a lower reflectivity than No. 4. It is produced with a pattern of very fine polishing lines. |
| No. 7 | A highly reflective finish that is obtained by polishing with successively finer abrasives and buffing extensively until all grit lines are removed. |
| No. 8 | Known as a "mirror finish". Highly reflective, with very clear image capabilities, achieved by polishing with successively finer abrasives followed by extensive buffing. |
| Hairline | A finish that results in long lines that extend along the length of the coil giving it a patterned texture which resembles hair strands. It's created through a continuous linear polishing. |
| Brushed or Satin Finish | Obtained by mechanically polishing the metal with fine abrasives to create a brushed appearance. Less reflective than No. 4 finish. |
| Bead Blasted | A matte finish with a frosted appearance produced by propelling a stream of abrasive material against the steel surface. |
| BA (Bright Annealed) | A highly reflective finish obtained by annealing in a controlled atmosphere to prevent oxidation, resulting in a bright and smooth surface. |
| PVD Coating | Physical Vapor Deposition is a process to produce a metal vapor that can be deposited as a thin, highly adhered pure metal or alloy coating. It is used to enhance surface properties such as color, corrosion resistance, and wear resistance. |
These finishes are used for various applications ranging from aesthetic considerations to functional purposes like enhanced corrosion resistance or reduced particle retention for better cleanability. Selection of the right finish will depend on the requirements of the application and the environment in which the stainless steel product will be used.
Stainless Steel Plate production process
The production process of a stainless steel plate involves several steps, each contributing to the final product's quality, properties, and characteristics. Here are the general stages:
Melting and Casting: The process begins with the melting of iron and alloying materials such as chromium, carbon, nickel, and others in an electric furnace. This process takes a few hours to complete, and the result is liquid stainless steel which is then cast into rectangular slabs or blooms, depending on the dimensions of the required final product.
Forming: The casted slabs or blooms are then rolled in a process known as hot-rolling to reduce the stainless steel's thickness and make flat, uniform sheets. The more a slab is rolled, the thinner it gets, forming a plate.
Heat Treatment (Annealing): After hot rolling, the plate goes through a heat treatment process to relieve stresses from the hot rolling and to enable recrystallization and grain refinement. This process, known as annealing, also enhances the ductility of the metal. The plate is heated and then cooled in a controlled environment.
Descaling: After the heat treatment process, a scale layer forms on the stainless steel, which must be removed. Frequently, this is achieved by pickling in acid or by blasting the surface with an abrasive substance (shot blasting).
Cold Rolling: Depending on the desired thickness, the stainless steel plate might go through further rolling under room temperature. This process is known as cold rolling. This step can help achieve a more precise dimension and improve surface quality.
Annealing and Descaling, Again: After cold rolling, the plate might be annealed and descaled again. This helps to further refine the crystalline structure and eliminate any remaining stresses.
Cutting: The rolls are cut into standard sizes and lengths based on market requirements.
Finishing: Finally, the stainless steel plate can be given a final finish, such as heat treating for hardening, polishing for shine, or being covered with a protective layer depending on the desired outcome and intended use.
Inspection and Testing: Before being shipped, the final plates are inspected and tested to ensure they meet the required characteristics and standards. This testing often includes chemical analysis, mechanical testing, and surface inspection.

Common forms of Stainless Steel Plate
Stainless steel plate is available in a variety of forms, which are designed to meet specific requirements concerning thickness, size, finish, and structural properties. Here are several common forms of stainless steel plate:
Hot Rolled, Annealed, and Pickled (HRAP) Stainless Steel Plates: Frequently used for applications requiring corrosion resistance, these plates have been heated above their recrystallization temperature and then cooled. This process relieves internal stresses and hardens the plate. Subsequently, it is thoroughly cleaned, or "pickled," in acid to remove scale.
Cold Rolled Stainless Steel Plates: These plates are hot-rolled stainless steel, but are then further reduced at room temperature under mildly critical conditions. This process increases the strength and hardness of the metal, improves surface smoothness, and brings tighter dimensional tolerances. These plates often have a slightly dull or matte finish.
Checkered or Diamond Plate: A pattern is added to one side of the plate, usually in a diamond-shaped grid or similar pattern, to provide additional grip. This is used for walkways, ramps, steps, truck beds, and similar applications where it's important to avoid slips and falls.
Perforated Stainless Steel Plate: Holes are punched into the plate for applications that need increased airflow or as part of the design, such as for filters or soundproof barriers.
Brushed or Satin Finish Plates: These plates have a finely scratched surface that hides fingerprints and is popular for architectural uses.
Mirror Finish Plates: These plates are polished to a highly reflective finish for decorative applications, such as mirrors or aesthetic elements in architecture.
These forms are available in a wide range of stainless steel grades, each of which has particular properties and are better suited to specific applications. Selecting the appropriate grade and form depends greatly on the intended use, environment, and requirements of the end result.
Stainless steel plate, known for its durability and high resistance to corrosion, is favorable across a wide range of industries and applications. Here are some of the primary advantages:
Corrosion Resistance: Most grades of stainless steel, including grade 304, provide excellent resistance to corrosion, largely due to the inclusion of chromium. This makes it suitable for use in environments that are corrosive or harsh, such as marine environments, chemical processing plants, etc.
High Temperature Resistance: Stainless steel can resist high temperature and maintain its strength and durability under extreme heat conditions, making it suitable for use in environments with high temperatures, such as aerospace and power generation industries.
Easy Maintenance and Cleaning: Stainless steel plates are easy to clean, making them popular in applications that prioritize hygiene, such as kitchen appliances, food processing equipment, hospitals, etc.
Longevity: Due to its high corrosion resistance and durability, stainless steel plate tends to have a long service life, reducing the need for replacement and thereby lowering costs in the long run.
Aesthetics: Stainless steel plates have a modern, clean look and can be finished in a variety of ways (such as brushed, satin, or mirror finish) to suit different visual preferences.
Non-Porous: Stainless steel plate is a non-porous material. This makes it ideal for use in the food industry as it does not absorb bacteria or odors, and it prevents the growth of bacteria and other pathogens.
Strength-to-Weight Advantage: Due to its structural strength, the thickness of stainless steel can be reduced without compromising integrity, leading to a significant strength-to-weight advantage over other materials.
Recyclability: Stainless steel is 100% recyclable, and a large amount of stainless steel is produced from previously recycled materials. This adds to its appeal from an environmental sustainability perspective.
These advantages make stainless steel plate a highly valuable material for various applications in industries such as construction, transportation, food service, medical, and more.
