A588 コルテン鋼の化学組成
| 要素 | 代表的な内容 (%) | 関数 |
|---|---|---|
| 炭素 (C) | 0.14 – 0.20 | Provides hardness and tensile strength |
| マンガン (ん) | 0.50 – 1.00 | Enhances strength and toughness |
| リン (P) | 0.07 – 0.15 | Promotes formation of a stable patina |
| 硫黄 (S) | ≤0.05 | Improves machinability |
| シリコン (そして) | 0.20 – 0.50 | Acts as a deoxidizer and strengthens steel |
| 銅 (銅) | 0.25 – 0.55 | Accelerates protective patina formation |
| クロム (Cr) | 0.40 – 1.25 | 耐大気腐食性の向上 |
| ニッケル (で) | 0.40 – 0.65 | Enhances toughness and durability |
A588 is designed to form a dense, reddish-brown protective oxide layer (緑青) that prevents deeper corrosion 屋外環境にさらされた場合. Compared to A242, A588 offers higher strength and improved corrosion resistance, making it suitable for structural and heavy-duty applications.
Key Mechanical Properties
