304 Stainless Steel Plate Encyclopedia: グレード, 規格, 仕様 & Selection Guide
304 stainless steel plate is the most widely used オーステナイト系ステンレス鋼 in the world. Known for its excellent balance of 耐食性, 成形性, 溶接性, とコスト効率, it is applied across industries such as construction, 食品機器, 化学処理, and general fabrication.
This guide provides a complete overview of 304 ステンレス鋼板, including international standards, 表面仕上げ, sizing options, and key selection considerations.
1. とは何ですか 304 ステンレス鋼板?
| 財産 | 詳細 |
|---|---|
| 鋼種 | オーステナイト系ステンレス鋼 |
| Main composition | 18% クロム, 8% ニッケル |
| 磁気 | Generally non-magnetic (焼きなまし状態) |
| 耐食性 | Excellent in most environments |
304 stainless steel is often referred to as the “general-purpose stainless steel” due to its wide adaptability.
2. International Standards: ASTM / 彼 / GB
| Standard System | 指定 | 説明 |
|---|---|---|
| ASTM (アメリカ合衆国) | ASTM A240 タイプ 304 | Most common plate specification |
| 彼 (日本) | SUS304 | Widely used in Asia-Pacific markets |
| GB (中国) | 06Cr19Ni10 | National standard equivalent |
Although naming differs, these standards refer to chemically equivalent materials with similar performance characteristics.
3. 一般的な表面仕上げ
- 2B仕上げ: スムーズ, マットな工業用表面
- BA仕上げ: 光輝焼鈍, 反射面
- No.4 brushed: Decorative linear texture
- 鏡 (8K): High-gloss reflective finish
| 仕上げタイプ | 主な用途 |
|---|---|
| 2B | 工業製造, タンク, 装置 |
| BA | 家電製品, 装飾パネル |
| つや消し | 建築, エレベーター, interiors |
| 鏡 | 豪華な装飾, デザインパネル |
4. Standard Specifications & 厚さの範囲
- 厚さ: typically 0.3mm – 100mm+
- 幅: commonly 1000mm, 1219mm, 1500mm
- 長さ: 2000mm, 2438mm, 3000mm or custom
304 stainless steel plates can be customized for cutting, 曲げ, and fabrication depending on project requirements.
5. Common Misunderstandings About 304 ステンレス鋼
- “304 never rusts” → Incorrect. It resists rust but can corrode in chloride-rich environments.
- “All stainless steel is the same” → Different grades have very different performance.
- “Thickness does not affect performance” → Structural strength depends heavily on thickness selection.
6. 代表的な用途 304 ステンレス鋼板
| 業界 | 応用例 |
|---|---|
| 工事 | 壁パネル, structural components |
| Food industry | 処理装置, タンク, surfaces |
| 化学工業 | Containers, パイプライン, 原子炉 |
| 家電製品 | 冷蔵庫, オーブン, パネル |
7. Selection Tips for Buyers
- Choose surface finish based on application (industrial vs decorative)
- Confirm standard (ASTM / 彼 / GB) before procurement
- Select thickness according to load requirements
- Consider corrosion environment before final selection
