ステンレス鋼板金のコスト
The cost of stainless steel sheet metal depends heavily on alloy composition and performance:
-
201 → most economical, suitable for low-corrosion environments
-
304 → best overall performance, widely used, medium price
-
410S → lower cost but limited corrosion resistance, suitable for specific industrial uses
- 説明
When evaluating the cost of stainless steel sheet metal, grades such as 201, 304, and 410S are commonly compared. Their prices vary significantly due to differences in 合金組成, 耐食性, そして機械的性能.
化学組成の比較
| 学年 | 主要な要素 | 特徴 |
|---|---|---|
| 201 | Cr 16 ～ 18%, 3.5 ～ 5.5% で, Mn 5.5～7.5% | 低ニッケル, manganese substitution |
| 304 | Cr 18 ～ 20%, 8～10.5% | 標準的なオーステナイト系ステンレス鋼 |
| 410S | Cr 11.5–13.5%, very low Ni | Ferritic/martensitic type, ニッケルなし |
性能比較
| 財産 | 201 | 304 | 410S |
|---|---|---|---|
| 耐食性 | 適度 | 素晴らしい | Low to moderate |
| 強さ | 高い | 中くらい | 高い |
| 延性 | 良い | 素晴らしい | より低い |
| 溶接性 | 適度 | 素晴らしい | 限定 |
| 磁気 | Slightly (冷間作業の後) | 非磁性 | 磁気 |
Cost Comparison
| 学年 | 価格レベル | 理由 |
|---|---|---|
| 201 | 最低 | ニッケル含有量の削減によりコストが削減されます |
| 304 | 中くらい | Balanced composition with higher nickel |
| 410S | 低から中程度 | No nickel but less corrosion resistance |
Why Prices Differ
1. ニッケル含有量
-
304 contains higher nickel → increases cost
-
201 replaces nickel with manganese → more economical
-
410S contains little to no nickel → lower raw material cost
2. 耐食性
-
優れた耐食性 (304) → higher value and price
-
Lower resistance (410S) → lower cost but limited applications
3. Processing and Applications
-
304 is easier to process and widely used → stable pricing
-
201 is used for cost-sensitive applications
-
410S is used where strength and heat resistance are more important than corrosion resistance
代表的な用途
