SUS 304 COLD Stainless Steel is a type of SUS 304 stainless steel that has been processed through cold rolling. This process enhances the strength, hardness, and precision of the steel compared to hot-rolled steel.

Key Characteristics of SUS 304 COLD Stainless Steel:

- Chemical Composition:
- Chromium (Cr): 18-20%, providing corrosion resistance.
- Nickel (Ni): 8-10.5%, improving ductility and heat resistance.
- Carbon (C): Up to 0.08%, maintaining corrosion resistance.
- Manganese (Mn): 2%, supporting the steel structure.
- Silicon (Si): 1%, enhancing corrosion resistance and machinability.

- Physical Properties:
- Corrosion Resistance: Good in various environments, particularly in moist and chemical conditions.
- Strength: Cold rolling increases the strength and hardness compared to hot-rolled steel.
- Ductility: Easily machinable, bendable, and cut without cracking or breaking.

- Applications:
- Manufacturing: Suitable for applications requiring a good surface finish and high precision, such as mechanical components, bolts, and screws.
- Food Processing: Used in food processing equipment and medical devices due to its corrosion resistance and ease of cleaning.
- Construction: Utilized in construction components, doors, and household appliances.

- Form and Size:
- SUS 304 COLD is typically available in sheets, bars, tubes, and wires, with sizes and shapes customized according to application needs.

Manufacturing and Processing:
- Production Process: SUS 304 COLD is produced through cold rolling, which enhances the steel’s strength, hardness, and precision.
- Machining: Can be machined using various mechanical methods such as cutting, drilling, and bending, while maintaining a good surface finish.
