SUS 430 2B Stainless Steel is a type of stainless steel in the chromium stainless steel group, with a 2B finish surface, commonly used in applications requiring both aesthetics and good corrosion resistance. The 2B finish is a cold-rolled surface with a dull shine, often used for products that require a non-reflective surface but still offer good corrosion resistance.

Key Characteristics of SUS 430 2B Stainless Steel:

- Chemical Composition:
- Carbon (C): Max 0.12%
- Chromium (Cr): 16.00-18.00%
- Nickel (Ni): Max 0.75%
- Manganese (Mn): Max 1.00%
- Silicon (Si): Max 1.00%
- Phosphorus (P): Max 0.04%
- Sulfur (S): Max 0.03%

- Physical Properties:
- Corrosion Resistance: Good in less aggressive environments, particularly in high humidity or exposure to certain chemicals.
- Hardness: High enough to provide good mechanical strength but not comparable to other stainless steels like SUS 304.
- Machinability: Easy to machine and weld due to good ductility.
- Aesthetics: The 2B finish provides a dull shine, suitable for applications requiring aesthetic appeal without a highly reflective surface.

- Applications:
- Household Industry: Used in household products such as sinks, stoves, and kitchen appliances.
- Automotive Industry: Used in exhaust system parts and other components requiring corrosion resistance and aesthetics.
- Construction Industry: Utilized in architectural accessories, partitions, and decorative products.

- Form and Size:
- SUS 430 2B is typically available in sheets, coils, bars, or custom-fabricated products depending on specific application requirements.

Manufacturing and Processing:
- Production Process: SUS 430 2B steel is produced through cold-rolling processes to achieve the 2B finish and desired mechanical properties.
- Machining: Can be easily machined and welded due to its good ductility.
