304 Stainless Steel Plate Encyclopedia: Notes, Normes, Caractéristiques & Guide de sélection
304 stainless steel plate is the most widely used acier inoxydable austénitique in the world. Known for its excellent balance of résistance à la corrosion, formabilité, soudabilité, et rentabilité, it is applied across industries such as construction, équipement alimentaire, traitement chimique, and general fabrication.
This guide provides a complete overview of 304 plaque en acier inoxydable, including international standards, finitions de surface, sizing options, and key selection considerations.
1. Qu'est-ce que 304 Plaque en acier inoxydable?
| Propriété | Détail |
|---|---|
| Steel type | Acier inoxydable austénitique |
| Main composition | 18% Chrome, 8% Nickel |
| Magnétisme | Generally non-magnetic (état recuit) |
| Résistance à la corrosion | 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 / IL / FR
| Standard System | Designation | Description |
|---|---|---|
| ASTM (USA) | Type ASTM A240 304 | Most common plate specification |
| IL (Japon) | SUS304 | Widely used in Asia-Pacific markets |
| FR (Chine) | 06Cr19Ni10 | National standard equivalent |
Although naming differs, these standards refer to chemically equivalent materials with similar performance characteristics.
3. Common Surface Finishes
- 2Finition B: Lisse, surface industrielle mate
- Finition BA: Recuit brillant, surface réfléchissante
- N°4 brossé: Decorative linear texture
- Miroir (8K): High-gloss reflective finish
| Type de finition | Application principale |
|---|---|
| 2B | Fabrication industrielle, réservoirs, equipment |
| BA | Appareils électroménagers, panneaux décoratifs |
| Brossé | Architecture, ascenseurs, interiors |
| Miroir | Décoration de luxe, design panels |
4. Standard Specifications & Plage d'épaisseur
- Épaisseur: typically 0.3mm – 100mm+
- Largeur: commonly 1000mm, 1219mm, 1500mm
- Longueur: 2000mm, 2438mm, 3000mm or custom
304 stainless steel plates can be customized for cutting, flexion, and fabrication depending on project requirements.
5. Common Misunderstandings About 304 Acier inoxydable
- “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. Applications typiques de 304 Plaque en acier inoxydable
| Industrie | Exemples d'application |
|---|---|
| Construction | Panneaux muraux, composants structurels |
| Industrie alimentaire | Équipement de traitement, réservoirs, surfaces |
| Industrie chimique | Containers, pipelines, réacteurs |
| Appareils électroménagers | Réfrigérateurs, fours, panneaux |
7. Selection Tips for Buyers
- Choose surface finish based on application (industrial vs decorative)
- Confirm standard (ASTM / IL / FR) before procurement
- Select thickness according to load requirements
- Consider corrosion environment before final selection
