Product Details
2mm 304 stainless steel sheet is a commonly used medium-thickness austenitic stainless steel product. It is widely applied in construction, machinery manufacturing, kitchen equipment, automotive components, and industrial fabrication due to its balanced strength, corrosion resistance, and workability.
This thickness is typically produced through cold rolling or hot rolling processes, depending on surface requirement, dimensional tolerance, and application purpose.
2mm Stainless Steel Sheet Thickness and Dimensional Characteristics
The nominal thickness of 2mm 304 stainless steel sheet refers to a final finished thickness after rolling and surface treatment.
| Item | Specification |
|---|---|
| Material Grade | 304 stainless steel |
| Nominal Thickness | 2.0 mm |
| Thickness Tolerance | Typically ±0.05 mm to ±0.15 mm (depends on standard) |
| Surface Types | 2B, BA (cold rolled), No.1 (hot rolled) |
| Processing Type | Cold rolled / Hot rolled |
Common sheet size formats include:
- 1000 mm × 2000 mm
- 1219 mm × 2438 mm
- 1500 mm × 3000 mm
- 1500 mm × 6000 mm
These sizes vary slightly depending on ASTM, EN, JIS, and GB production standards.
Cold Rolled 304 Stainless Steel Sheet (CR)
Cold rolled stainless steel is the most common production route for 2mm sheets when high surface quality and tight dimensional tolerance are required.
Key characteristics:
- Smooth surface finish (commonly 2B or BA)
- High dimensional accuracy
- Better flatness and consistency
- Slightly higher strength due to work hardening
- Suitable for precision fabrication and decorative use
Cold rolled 2mm stainless steel sheet is widely used in:
- Kitchen equipment
- Architectural panels
- Precision machinery parts
- Electrical enclosures
Hot Rolled 304 Stainless Steel Sheet (HR)
Hot rolled stainless steel is processed at high temperature and is generally used for thicker plates and structural applications.
Is there thin hot rolled stainless steel sheet?
Yes, hot rolled stainless steel sheets can be produced in relatively thin gauges, but they are less common compared to cold rolled products. In most industrial standards:
- Hot rolled stainless steel typically starts from around 3.0 mm thickness and above
- Some mills can produce thinner hot rolled sheets, but surface quality and flatness are lower than cold rolled sheets
- Thin hot rolled sheets are usually used for non-decorative structural applications
Characteristics of hot rolled stainless steel:
- Rough surface finish (typically No.1 finish)
- Lower dimensional precision compared to cold rolled
- Better suitability for heavy structural applications
- Lower internal stress in thicker sections
Cold Rolled vs Hot Rolled Comparison for 2mm Stainless Steel
| Feature | Cold Rolled (CR) | Hot Rolled (HR) |
|---|---|---|
| Surface Finish | Smooth, uniform (2B/BA) | Rough, matte (No.1) |
| Thickness Accuracy | High precision | Lower precision |
| Flatness | Excellent | Moderate |
| Typical Thickness Range | Thin to medium (0.3–6 mm) | Medium to thick (generally ≥3 mm, sometimes lower) |
| Application | Decorative, precision parts | Structural, industrial components |
