316 Stainless Steel Sheets
316 Stainless Steel Sheets offer clear advantages over other 300 series stainless steels, especially in environments involving chlorides, seawater, and chemical exposure. Compared with 304, 321, and 310S, 316 provides a more balanced combination of corrosion resistance, mechanical performance, and processing capability, making it the preferred choice for demanding industrial applications where durability and reliability are critical.
- Description
316 Stainless Steel Sheets are a widely used austenitic stainless steel product in the 300 series. They are designed with added molybdenum (Mo), which significantly improves corrosion resistance, especially in chloride-rich and marine environments. Compared with other 300 series stainless steels, 316 offers enhanced durability and chemical stability.
Key Characteristics of 316 Stainless Steel Sheets
- 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)
- Good weldability and formability
Chemical Composition (Typical)
| Element | Content (%) |
|---|---|
| Chromium (Cr) | 16.0 – 18.0 |
| Nickel (Ni) | 10.0 – 14.0 |
| Molybdenum (Mo) | 2.0 – 3.0 |
| Carbon (C) | ≤ 0.08 |
| Manganese (Mn) | ≤ 2.0 |
| Iron (Fe) | Balance |
The key difference is the addition of molybdenum, which is not present in most other standard 300 series grades like 304.
