Chemical Composition of A242 Corten Steel
| 要素 | 代表的な内容 (%) | 関数 |
|---|---|---|
| 炭素 (C) | 0.12 – 0.20 | 強度と硬度を提供します |
| マンガン (ん) | 0.50 – 1.00 | Enhances tensile strength and toughness |
| リン (P) | 0.07 – 0.15 | Promotes formation of stable patina |
| 硫黄 (S) | ≤0.05 | Improves machinability in small amounts |
| シリコン (そして) | 0.20 – 0.50 | Acts as a deoxidizer and enhances strength |
| 銅 (銅) | 0.25 – 0.55 | Accelerates patina formation and improves corrosion resistance |
| クロム (Cr) | 0.50 – 1.25 | Increases resistance to atmospheric corrosion |
| ニッケル (で) | 0.25 – 0.65 | Improves toughness and durability |
A242 Corten steel is engineered to develop a stable reddish-brown patina that protects the underlying steel from further corrosion when exposed to outdoor environments.
