3mm Stainless Steel Plate Price
The difference between cold rolled and hot rolled 3mm stainless steel plates directly affects both application and price.
- Cold rolled plates offer better surface quality and precision
- Hot rolled plates provide cost efficiency and structural strength
- Description
3mm stainless steel plate is a widely used thickness in industrial and architectural applications. It offers a balance between strength, corrosion resistance, and workability.
When discussing 3mm stainless steel plate price, one of the key influencing factors is the production process, mainly divided into:
- Cold rolled stainless steel plate (CR)
- Hot rolled stainless steel plate (HR)
These two types differ significantly in surface quality, mechanical properties, and application fields.
Cold Rolled 3mm Stainless Steel Plate
Manufacturing Characteristics
- Processed at room temperature after hot rolling
- Further rolling improves surface finish and dimensional accuracy
- Typically supplied with smooth finishes such as 2B, BA, or mirror
Key Features
- High surface quality and flatness
- Precise thickness tolerance
- Better appearance for decorative use
- Higher production cost compared to hot rolled
Common Applications
1. Architectural and Decorative Use
- Elevator panels
- Wall cladding and interior decoration
- Ceiling and facade panels
2. Precision Fabrication
- Kitchen equipment
- Food processing machinery
- Medical equipment
3. Light Industrial Components
- Enclosures and cabinets
- Sheet metal fabrication parts
Cold rolled 3mm stainless steel plates are mainly used where surface quality and appearance are critical.
Hot Rolled 3mm Stainless Steel Plate
Manufacturing Characteristics
- Rolled at high temperature (above recrystallization temperature)
- Produced directly from slabs
- Surface is relatively rough, often requiring further processing
Key Features
- Lower cost compared to cold rolled
- Good mechanical strength
- Less strict dimensional tolerance
- Surface typically in No.1 finish
Common Applications
1. Structural and Engineering Use
- Steel structures and frames
- Industrial platforms
- Load-bearing components
2. Heavy Equipment Manufacturing
- Machinery parts
- Pressure vessels
- Storage tanks
3. Industrial Fabrication
- Base plates and supports
- Welding structures
Hot rolled 3mm plates are preferred where strength and cost efficiency are more important than appearance.
Cold Rolled vs Hot Rolled – Comparison
| Feature | Cold Rolled (CR) | Hot Rolled (HR) |
|---|---|---|
| Surface Finish | Smooth, bright | Rough, scaled |
| Thickness Accuracy | High | Moderate |
| Strength | Slightly higher due to work hardening | Good structural strength |
| Cost | Higher | Lower |
| Main Use | Decorative, precision | Structural, industrial |
Impact on Price
For 3mm stainless steel plates:
- Cold rolled plates → Higher price due to additional processing and better surface quality
- Hot rolled plates → More cost-effective for large-scale structural use
Other factors affecting price include:
- Stainless steel grade (e.g., 304, 316, 430)
- Surface finish (2B, BA, No.1, mirror)
- Order quantity and processing requirements
Application Selection Guide
- Choose cold rolled 3mm stainless steel plate for:
- Decorative panels
- Food-grade and hygienic environments
- Precision fabrication
- Choose hot rolled 3mm stainless steel plate for:
- Structural components
- Heavy-duty industrial use
- Cost-sensitive projects
