316 Ss Lembaran Logam
316 SS sheet metal offers stronger corrosion resistance than 304 due to its molybdenum content, making it ideal for marine and chemical applications. Berbanding dengan 314 keluli tahan karat, 316 performs better in corrosive environments, sementara 314 is more suitable for high-temperature service.
Antara gred ini:
- 304 is the standard general-purpose stainless steel
- 316 is preferred for corrosion resistance
- 314 is designed for high-temperature applications
- Penerangan
316 SS sheet metal is a high-performance austenitic stainless steel sheet widely used in marine equipment, pemprosesan kimia, and food-grade industries. Berbanding dengan 304 keluli tahan karat, 316 menawarkan rintangan kakisan yang lebih baik kerana penambahan molibdenum. It is also often compared with 314 keluli tahan karat, which is known for high-temperature oxidation resistance.
Memahami perbezaan antara 316, 314, dan 304 kepingan logam keluli tahan karat helps buyers choose the right material for corrosive, suhu tinggi, or general-purpose applications.
Apa Itu 316 SS Sheet Metal?
316 stainless steel sheet metal is an austenitic stainless steel containing chromium, nikel, dan Molybdenum. The molybdenum content gives it stronger resistance to chloride corrosion and pitting than standard 304 keluli tahan karat.
Aplikasi biasa termasuk:
- Tangki kimia
- Struktur marin
- Penukar haba
- Peralatan pemprosesan makanan
- Peralatan farmaseutikal
- Peranti perubatan
316 sheet is commonly supplied in cold rolled and hot rolled forms, with surface finishes such as 2B, BA, No.4, and mirror.
Perbandingan Komposisi Kimia
Perbezaan utama antara 304, 314, dan 316 stainless steel lies in alloy composition.
| Gred | Chromium (%) | Nikel (%) | Molibdenum (%) | Ciri Utama |
|---|---|---|---|---|
| 304 | 18–20 | 8–10.5 | — | Rintangan kakisan am |
| 316 | 16–18 | 10–14 | 2–3 | Rintangan klorida |
| 314 | 24–26 | 19–22 | — | Rintangan suhu tinggi |
316 includes molybdenum, sementara 314 contains higher chromium and nickel for superior heat resistance.
Corrosion Resistance Comparison
316 lwn 304
316 stainless steel has better corrosion resistance than 304, terutamanya dalam:
- Saltwater environments
- Coastal areas
- Chemical plants
- Acidic processing environments
This is because molybdenum improves resistance to pitting and crevice corrosion.
316 lwn 314
314 stainless steel is not primarily designed for wet corrosion resistance. It is mainly used for high-temperature applications.
For humid or chloride environments, 316 is usually preferred.
Heat Resistance Comparison
314 stainless steel is well known for excellent oxidation resistance at elevated temperatures.
| Gred | Suhu Perkhidmatan Maks |
|---|---|
| 304 | About 870°C |
| 316 | About 870°C |
| 314 | About 1150°C |
314 performs significantly better in furnaces, tanur, and heat treatment equipment.
If high-temperature service is the main requirement, 314 is generally superior.
Mechanical Property Comparison
| Harta benda | 304 | 316 | 314 |
|---|---|---|---|
| Kekuatan Tegangan | ≥ 515 MPa | ≥ 515 MPa | ≥ 520 MPa |
| Kekuatan Hasil | ≥ 205 MPa | ≥ 205 MPa | ≥ 210 MPa |
| Pemanjangan | ≥ 40% | ≥ 40% | ≥ 40% |
The mechanical properties are relatively similar, but service environment determines material selection.

Which Grade Is Better?
The best stainless steel sheet depends on the service environment.
| Keperluan | Recommended Grade |
|---|---|
| General indoor use | 304 |
| Marin / chemical environment | 316 |
| High temperature above 1000°C | 314 |
316 stainless steel sheet metal is often selected when corrosion resistance is more important than cost, especially in harsh industrial conditions.
