316 ステンレス鋼板
316 ステンレス鋼板 offer clear advantages over other 300 シリーズステンレス鋼, especially in environments involving 塩化物, 海水, and chemical exposure. と比較して 304, 321, and 310S, 316 provides a more balanced combination of 耐食性, mechanical performance, and processing capability, making it the preferred choice for demanding industrial applications where durability and reliability are critical.
- 説明
316 ステンレス鋼板 are a widely used austenitic stainless steel product in the 300 シリーズ. They are designed with added molybdenum (モー), which significantly improves corrosion resistance, especially in chloride-rich and marine environments. 他と比べて 300 シリーズステンレス鋼, 316 offers enhanced durability and chemical stability.
主な特徴 316 ステンレス鋼板
- 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)
- 溶接性、成形性が良好
化学組成 (典型的な)
| 要素 | コンテンツ (%) |
|---|---|
| クロム (Cr) | 16.0 – 18.0 |
| ニッケル (で) | 10.0 – 14.0 |
| モリブデン (モー) | 2.0 – 3.0 |
| 炭素 (C) | ≤ 0.08 |
| マンガン (ん) | ≤ 2.0 |
| 鉄 (鉄) | バランス |
The key difference is the addition of molybdenum, which is not present in most other standard 300 series grades like 304.
