Product Details
Stainless Steel Plate is a widely used corrosion-resistant metal material applied in construction, machinery, chemical equipment, and transportation. It is available in a variety of thicknesses and production processes, mainly classified into hot-rolled (HR) and cold-rolled (CR) stainless steel plates.
Common Thickness Specifications
Stainless steel plates are produced in a wide thickness range to meet different structural and processing requirements.
Typical Thickness Range
| Category | Thickness Range | Application Type |
|---|---|---|
| Thin Sheet | 0.3 – 3.0 mm | Decorative panels, appliances, light fabrication |
| Medium Plate | 3.0 – 10.0 mm | Machinery parts, structural components |
| Heavy Plate | 10.0 – 50.0 mm | Pressure vessels, industrial equipment |
| Extra Heavy Plate | 50.0 mm and above | Heavy engineering, shipbuilding, infrastructure |
Common Standard Thicknesses
- 0.5 mm
- 0.8 mm
- 1.0 mm
- 1.2 mm
- 1.5 mm
- 2.0 mm
- 3.0 mm
- 5.0 mm
- 8.0 mm
- 10 mm
- 12 mm
- 20 mm
- 30 mm
These sizes are widely stocked for industrial and commercial use.
Hot Rolled vs Cold Rolled Stainless Steel Plate
Stainless steel plates are mainly produced using two different rolling processes, which significantly affect surface quality, mechanical properties, and applications.
1. Hot Rolled Stainless Steel Plate (HR)
Hot rolling is performed at high temperatures (above recrystallization temperature).
Characteristics
- Rougher surface finish (typically No.1 finish)
- Slightly lower dimensional accuracy
- Higher thickness range availability
- Lower production cost
- Easier for heavy forming and welding
Advantages
- Suitable for thick plates
- Good structural strength
- Cost-effective for large-scale projects
- Better for heavy fabrication
Applications
- Construction structures
- Shipbuilding
- Pressure vessels
- Industrial machinery bases
2. Cold Rolled Stainless Steel Plate (CR)
Cold rolling is performed at room temperature with higher precision processing.
Characteristics
- Smooth and bright surface (2B, BA finish)
- High dimensional accuracy
- Improved mechanical strength
- More uniform thickness control
- Higher production cost
Advantages
- Excellent surface quality
- Better precision and flatness
- Higher strength due to work hardening
- Suitable for decorative and precision applications
Applications
- Kitchen equipment
- Medical instruments
- Electronic enclosures
- Architectural decoration
- Precision machinery parts
Hot Rolled vs Cold Rolled Comparison
| Property | Hot Rolled Plate | Cold Rolled Plate |
| Surface Finish | Rough (No.1) | Smooth (2B/BA) |
| Dimensional Accuracy | Medium | High |
| Strength | Standard | Higher |
| Thickness Range | Thick plates | Thin to medium plates |
| Cost | Lower | Higher |
| Application Type | Structural | Precision & decorative |
Common Stainless Steel Grades
- 304 / 304L – general corrosion-resistant use
- 316 / 316L – marine and chemical environments
- 430 – economical ferritic stainless steel
- 201 – cost-effective alternative for decoration
- 2205 – duplex stainless steel for high strength
