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. Dibandingkan dengan 314 baja tahan karat, 316 performs better in corrosive environments, ketika 314 is more suitable for high-temperature service.
Di antara nilai-nilai ini:
- 304 is the standard general-purpose stainless steel
- 316 is preferred for corrosion resistance
- 314 is designed for high-temperature applications
- Keterangan
316 SS sheet metal is a high-performance austenitic stainless steel sheet widely used in marine equipment, Pemrosesan Kimia, and food-grade industries. Dibandingkan dengan 304 baja tahan karat, 316 menawarkan peningkatan ketahanan terhadap korosi karena penambahan molibdenum. It is also often compared with 314 baja tahan karat, which is known for high-temperature oxidation resistance.
Memahami perbedaan antara 316, 314, Dan 304 lembaran logam baja tahan karat helps buyers choose the right material for corrosive, suhu tinggi, or general-purpose applications.
Apa 316 SS Sheet Metal?
316 stainless steel sheet metal is an austenitic stainless steel containing chromium, nikel, dan molibdenum. The molybdenum content gives it stronger resistance to chloride corrosion and pitting than standard 304 baja tahan karat.
Aplikasi yang umum termasuk:
- Tangki kimia
- Struktur laut
- Penukar panas
- Peralatan pengolahan makanan
- Peralatan farmasi
- Medical devices
316 sheet is commonly supplied in cold rolled and hot rolled forms, with surface finishes such as 2B, BA, No.4, dan cermin.
Perbandingan Komposisi Kimia
Perbedaan utama antara 304, 314, Dan 316 stainless steel lies in alloy composition.
| Nilai | Kromium (%) | Nikel (%) | molibdenum (%) | Fitur Utama |
|---|---|---|---|---|
| 304 | 18–20 | 8–10.5 | — | Ketahanan korosi secara umum |
| 316 | 16–18 | 10–14 | 2–3 | Resistensi klorida |
| 314 | 24–26 | 19–22 | — | Tahan suhu tinggi |
316 includes molybdenum, ketika 314 contains higher chromium and nickel for superior heat resistance.
Corrosion Resistance Comparison
316 vs 304
316 stainless steel has better corrosion resistance than 304, terutama di:
- Saltwater environments
- Coastal areas
- Chemical plants
- Acidic processing environments
This is because molybdenum improves resistance to pitting and crevice corrosion.
316 vs 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.
| Nilai | Suhu Layanan Maks |
|---|---|
| 304 | About 870°C |
| 316 | About 870°C |
| 314 | About 1150°C |
314 performs significantly better in furnaces, tempat pembakaran, and heat treatment equipment.
If high-temperature service is the main requirement, 314 is generally superior.
Perbandingan Properti Mekanik
| Milik | 304 | 316 | 314 |
|---|---|---|---|
| Kekuatan Tarik | ≥ 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.
