Processing methods and applications of common stainless steel surfaces
No.1 stainless steel surface:
Processing method: Surface No.1 is cleaned with chemicals and annealed after the hot rolling stage.
Application: Suitable for making industrial tanks, cold rolling, and tools in the chemical industry.
No.1 stainless steel surface
No.2D stainless steel surface:
Processing method: No.2D surface has no gloss, after the cold rolling stage, the product is treated with chemicals.
Application: Used in petrochemical plant equipment, auto parts, construction materials and stainless steel pipes.
No.2D stainless steel surface
2B stainless steel surface:
Processing method: 2B surface is smoother than No.2D, and has more gloss and smoothness.
Application: Popular in making solar water heaters, water tanks, and other products in many different fields.
2B stainless steel surface
No.3 stainless steel surface:
Processing method: No.3 surface is polished with a polishing pad with a density of 100 to 200 mesh.
Application: Often used in interior and exterior decoration, household appliances and kitchen utensils.
No.3 stainless steel surface
No.4 stainless steel surface:
Processing method: No.4 surface is polished with a density of 150 to 180 mesh, providing a higher gloss than No.3.
Application: Often used in making bathtubs, exterior decoration, and tools in the food processing industry.
No.4 stainless steel surface
BA stainless steel surface
Processing method: The BA surface is cared for and polished after the cold rolling process, creating a shiny, mirror-like surface.
Application: Suitable for household appliances, small mirrors, kitchen utensils, construction materials and items that require a shiny surface.
BA stainless steel surface
8K stainless steel surface:
8K stainless steel surface is popular on 304 and 201 stainless steel plates, created by continuous polishing from BA, 2B, No. 8K stainless steel has a bright and clear surface like a mirror.
Application: Often used in interior and exterior decoration.
Dull stainless steel surface:
Dull stainless steel surface is a type of stainless steel with a dull surface, created by reducing the gloss of 2B stainless steel and creating a rough surface.
Application: Often used to make elevator ceilings and walls in interior and exterior decoration.
Superior properties of stainless steel surfaces
Corrosion resistance
The most outstanding advantage of stainless steel surfaces is their extremely high corrosion resistance, allowing it to be exposed to a variety of chemicals in different environments. Thanks to its good rust resistance and food safety, stainless steel is often used in the production of tools for the food processing, medicine, and dyeing industries,…
High heat resistance
The heat resistance of each type of stainless steel surface may be different. For example, Stainless Steel 304 has good oxidation resistance at 870 degrees Celsius and can withstand heat up to 925 degrees Celsius, making it suitable for devices that require good heat resistance.
Ability to shape and process
Stainless steel surfaces have good shaping and machining capabilities thanks to their ductility and weldability. This allows stainless steel to be laminated without having to use heating methods, commonly applied in the production of stainless steel parts.
Stainless steel surfaces can be shaped and machined
Mechanical and physical properties
Under normal conditions, the surface of stainless steel, also known as Austenitic stainless steel, has very weak magnetism (almost non-existent). However, in low temperature environments or after undergoing angle cutting processes, the magnetism of 304 stainless steel can become strong.
