Austenite Stainless Steel Material Grade
| Stainless Steel Surface Finishes | Description | Application |
| No.1 | The No. 1 surface of stainless steel is finished by annealing and pickling after hot rolling production. It is characterized by a rough, dull, and non-reflective appearance. | No.1 Stainless Steel is commonly used in applications where the surface finish is not critical, such as for industrial equipment, furnace parts, and other applications where a coarse finish is acceptable. |
| 2B | The 2B surface finish of stainless steel is a smooth and reflective finish produced through cold rolling, followed by annealing, pickling, and a final cold rolling pass on polished rolls. This finish provides an attractive, uniform appearance that is easy to clean and has excellent corrosion resistance. | The 2B surface finish of stainless steel is commonly used in a variety of applications, including kitchen equipment, food processing, chemical containers, and architectural panels, where both aesthetics and functionality are important. |
| BA (Bright Annealed) | The BA (Bright Annealed) surface finish of stainless steel is characterized by its highly reflective, mirror-like appearance. This finish is achieved by bright annealing in a controlled atmosphere furnace, which prevents oxidation and ensures a smooth and bright surface. | The BA surface finish of stainless steel is often used in applications where an attractive, high-gloss appearance is essential, such as in architectural elements, household appliances, and automotive trim. |
| No. 4 | The No. 4 surface finish of stainless steel, also known as a brushed or satin finish, is characterized by its fine, directional grit lines and a moderately reflective appearance. This finish is achieved by mechanical polishing with abrasive belts or brushes, typically using a 150-180 grit size. | The No. 4 surface finish of stainless steel is widely used in both functional and decorative applications, including kitchen equipment, architectural panels, elevator interiors, and automotive trim. |
| HL (Hair Line) | The hairline surface finish of stainless steel is characterized by its fine, continuous, unidirectional lines that resemble strands of hair. This finish is achieved through a precision grinding process using specialized abrasive belts. | The hairline surface finish of stainless steel is commonly used in high-end architectural applications, interior design, and premium consumer products, such as kitchen appliances and electronic devices. |
| SB (Scotch-Brite) | The SB (Scotch-Brite) surface finish of stainless steel is achieved using Scotch-Brite abrasive pads, resulting in a fine, matte texture with a uniform appearance. This finish is noted for its ability to diffuse light, minimizing the visibility of fingerprints and small scratches. | The SB surface finish of stainless steel is commonly used in commercial kitchen equipment, elevators, and architectural applications |
| NO.8 (Mirror) | The No. 8 surface finish of stainless steel is characterized by its highly reflective, mirror-like appearance. This finish is achieved through extensive polishing with progressively finer abrasives to achieve a bright mirror-like surface. | The No. 8 surface finish of stainless steel is often used in decorative and architectural applications where a flawless, high-gloss look is essential, such as in mirrors, decorative trim, and high-end appliances. |
| Etching | The Etching surface finish of stainless steel is characterized by its intricate, decorative patterns or designs that are created through a controlled chemical etching process. | Etched stainless steel is commonly used in architectural applications, signage, elevator panels, and custom design projects. |
| Checker Plate | The Checker Plate surface finish of stainless steel, also known as tread plate or diamond plate, is characterized by a raised pattern of lines or diamonds on one side. | Checker Plate is widely used in applications where slip resistance and durability are crucial, such as in flooring, stair treads, ramps, and industrial platforms. |
