DESCRIPTION
SUS 304 2B Stainless Steel is a common variant of SUS 304 stainless steel, finished with a 2B surface. It is an austenitic stainless steel known for its excellent corrosion resistance, high strength, and good formability, making it one of the most widely used stainless steels.
Key Characteristics of SUS 304 2B Stainless Steel:
- Chemical Composition:
- Carbon (C): Maximum 0.08%, helps reduce the susceptibility of the steel to intergranular corrosion.
- Chromium (Cr): 18.0-20.0%, provides corrosion and oxidation resistance.
- Nickel (Ni): 8.0-10.5%, enhances corrosion resistance and ductility.
- Manganese (Mn): Maximum 2.0%, improves machinability.
- Silicon (Si): Maximum 1.0%, contributes to strength and corrosion resistance.
- Phosphorus (P) and Sulfur (S): Both are present in maximum amounts of 0.045% and 0.030% respectively, maintaining the steel's high purity.
- 2B Surface Finish:
- Surface Finish: The 2B finish is achieved through cold rolling, followed by heat treatment and light polishing. The result is a smooth, slightly reflective surface that is ideal for both aesthetic and technical applications.
- Surface Characteristics: The 2B surface is more resistant to staining and easier to clean, making it suitable for applications in food, medical, and industrial environments.
- Physical Properties:
- Corrosion Resistance: SUS 304 2B offers good corrosion resistance in various environments, including humid and mildly corrosive chemical settings.
- Strength and Ductility: Combines high tensile strength with ductility, making it easy to machine and form.
- Heat Resistance: SUS 304 2B has good heat resistance, suitable for applications requiring high-temperature tolerance.
- Applications:
- Food and Medical Industry: Used in manufacturing food processing equipment, medical instruments, and surfaces requiring high hygiene standards.
- Household Appliances: Used in making kitchen equipment, refrigerators, and washing machines.
- Decorative and Construction: Applied in architectural projects, facades, and interior details due to its smooth, easy-to-maintain surface.
- Chemical Industry: Used in tanks, pipes, and chemical processing equipment due to its corrosion resistance.
Manufacturing and Processing:
- Production Process: SUS 304 2B is produced through modern metallurgical processes, including cold rolling to achieve the desired thickness, followed by heat treatment and surface treatment to create the 2B finish.
- Fabrication: This steel is easily weldable, cuttable, bendable, and polishable, making it suitable for a wide range of manufacturing processes.
