Stainless Steel Sheet vs Plate: What’s the Difference in Thickness, Piawaian & Aplikasi?
The terms kepingan keluli tahan karat dan plat keluli tahan karat are often used interchangeably, but in metallurgy and industrial purchasing, they refer to different thickness ranges, processing methods, and application scenarios.
Understanding the distinction is essential for correct material selection in construction, rekaan, dan projek kejuruteraan.
1. Sheet vs Plate: Core Definition
| kategori | Ketebalan Biasa | Kegunaan Utama |
|---|---|---|
| Lembaran keluli tahan karat | 0.3mm – 6mm | Panel hiasan, peralatan, fabrikasi ringan |
| Plat keluli tahan karat | 6mm – 100mm+ | Bahagian struktur, heavy equipment, kapal tekanan |
Secara amnya, thin materials are called sheets, sementara thicker materials are called plates.
2. Key Differences Between Sheet and Plate
| Harta benda | Lembaran | Pinggan |
|---|---|---|
| Ketebalan | Nipis | tebal |
| Fleksibiliti | tinggi (mudah dibentuk) | rendah (structural rigidity) |
| kekuatan | Sederhana | tinggi |
| Memproses | Memotong, membengkok, mengecap | Pemesinan, mengimpal, fabrikasi berat |
3. International Standards for Stainless Steel Sheet & Pinggan
- ASTM A240: Most widely used standard in global markets
- JIS G4304 / G4305: Japanese industrial standard system
- DALAM 10088: European stainless steel specification
- GB/T 3280: Chinese national standard
These standards define chemical composition, sifat mekanikal, and dimensional tolerances for both sheet and plate products.
4. Common Grades Used in Sheet & Pinggan
| Gred | Ciri-ciri | Penggunaan Biasa |
|---|---|---|
| 304 | Rintangan kakisan tujuan am | Dapur, pembinaan, peralatan |
| 316 | Rintangan klorida yang lebih baik | Marin, persekitaran kimia |
| 430 | Feritik, kos efektif | Perkakas, kegunaan hiasan |
| 2205 | Duplex high strength | Luar pesisir, pressure systems |
5. Perbezaan Aplikasi
| industri | Sheet Usage | Plate Usage |
|---|---|---|
| Pembinaan | Pelapisan dinding, hiasan | Structural support, base plates |
| Pembuatan | kandang, panel | Bingkai mesin, heavy components |
| Tenaga | Penutup cahaya, perumahan | Kapal tekanan, reaktor |
| Pengangkutan | Panel dalaman | Structural chassis components |
6. Common Selection Mistakes
- Confusing sheet and plate thickness ranges
- Ignoring load-bearing requirements
- Choosing decorative-grade sheet for structural use
- Overpaying for plate when sheet is sufficient
