316 Lembaran Keluli Tahan Karat
316 Lembaran Keluli Tahan Karat offer clear advantages over other 300 series stainless steels, especially in environments involving klorida, air laut, and chemical exposure. Berbanding dengan 304, 321, and 310S, 316 provides a more balanced combination of rintangan kakisan, prestasi mekanikal, and processing capability, making it the preferred choice for demanding industrial applications where durability and reliability are critical.
- Penerangan
316 Lembaran Keluli Tahan Karat are a widely used austenitic stainless steel product in the 300 siri. They are designed with added molybdenum (Mo), which significantly improves corrosion resistance, especially in chloride-rich and marine environments. Berbanding dengan yang lain 300 series stainless steels, 316 offers enhanced durability and chemical stability.
Ciri-ciri Utama 316 Lembaran Keluli Tahan Karat
- Excellent corrosion resistance in aggressive environments
- Strong resistance to pitting and crevice corrosion
- Good performance in seawater and chloride exposure
- Stable austenitic structure (non-magnetic in annealed condition)
- Kebolehkimpalan dan kebolehbentukan yang baik
Komposisi Kimia (tipikal)
| unsur | kandungan (%) |
|---|---|
| Chromium (Cr) | 16.0 – 18.0 |
| Nikel (Dalam) | 10.0 – 14.0 |
| Molibdenum (Mo) | 2.0 – 3.0 |
| Karbon (C) | ≤ 0.08 |
| Mangan (Mn) | ≤ 2.0 |
| Besi (Fe) | Keseimbangan |
The key difference is the addition of molybdenum, which is not present in most other standard 300 series grades like 304.
