304 Stainless Steel Plate Encyclopedia: Grades, Standards, Specifications & Selection Guide
304 stainless steel plate is the most widely used austenitic stainless steel in the world. Known for its excellent balance of corrosion resistance, formability, weldability, and cost efficiency, it is applied across industries such as construction, food equipment, chemical processing, and general fabrication.
This guide provides a complete overview of 304 stainless steel plate, including international standards, surface finishes, sizing options, and key selection considerations.
1. What is 304 Stainless Steel Plate?
| Property | Detail |
|---|---|
| Steel type | Austenitic stainless steel |
| Main composition | 18% Chromium, 8% Nickel |
| Magnetism | Generally non-magnetic (annealed condition) |
| Corrosion resistance | Excellent in most environments |
304 stainless steel is often referred to as the “general-purpose stainless steel” due to its wide adaptability.
2. International Standards: ASTM / JIS / GB
| Standard System | Designation | Description |
|---|---|---|
| ASTM (USA) | ASTM A240 Type 304 | Most common plate specification |
| JIS (Japan) | SUS304 | Widely used in Asia-Pacific markets |
| GB (China) | 06Cr19Ni10 | National standard equivalent |
Although naming differs, these standards refer to chemically equivalent materials with similar performance characteristics.
3. Common Surface Finishes
- 2B finish: Smooth, matte industrial surface
- BA finish: Bright annealed, reflective surface
- No.4 brushed: Decorative linear texture
- Mirror (8K): High-gloss reflective finish
| Finish Type | Main Application |
|---|---|
| 2B | Industrial fabrication, tanks, equipment |
| BA | Appliances, decorative panels |
| Brushed | Architecture, elevators, interiors |
| Mirror | Luxury decoration, design panels |
4. Standard Specifications & Thickness Range
- Thickness: typically 0.3mm – 100mm+
- Width: commonly 1000mm, 1219mm, 1500mm
- Length: 2000mm, 2438mm, 3000mm or custom
304 stainless steel plates can be customized for cutting, bending, and fabrication depending on project requirements.
5. Common Misunderstandings About 304 Stainless Steel
- “304 never rusts” → Incorrect. It resists rust but can corrode in chloride-rich environments.
- “All stainless steel is the same” → Different grades have very different performance.
- “Thickness does not affect performance” → Structural strength depends heavily on thickness selection.
6. Typical Applications of 304 Stainless Steel Plate
| Industry | Application Examples |
|---|---|
| Construction | Wall panels, structural components |
| Food industry | Processing equipment, tanks, surfaces |
| Chemical industry | Containers, pipelines, reactors |
| Appliances | Refrigerators, ovens, panels |
7. Selection Tips for Buyers
- Choose surface finish based on application (industrial vs decorative)
- Confirm standard (ASTM / JIS / GB) before procurement
- Select thickness according to load requirements
- Consider corrosion environment before final selection
