A606 コルテン
A606 Corten steel offers an excellent balance of 耐食性, 成形性, and aesthetic appeal. Its alloy composition allows it to develop a 自己保護錆層, making it a preferred material for architectural design, landscaping products, and outdoor sheet metal applications.
- 説明
A606 Corten steel (ASTM A606) です 高強度, low-alloy (HSLA) weathering steel sheet widely used in architectural and outdoor applications. It is especially known for its ability to develop a stable rust patina, which protects the material from further corrosion.
Chemical Composition of A606 Corten
The composition of A606 steel is designed to enhance atmospheric corrosion resistance:
| 要素 | コンテンツ (%) |
|---|---|
| 炭素 (C) | ≤ 0.22 |
| シリコン (そして) | ≤ 0.40 |
| マンガン (ん) | ≤ 1.35 |
| リン (P) | ≤ 0.04 |
| 硫黄 (S) | ≤ 0.05 |
| 銅 (銅) | ≥ 0.20 |
| クロム (Cr) | ≤ 0.50 |
| ニッケル (で) | ≤ 0.50 |
Key Alloying Elements
-
銅 (銅): 耐食性の向上
-
クロム (Cr): 耐酸化性を高める
-
ニッケル (で): Increases durability in harsh environments
機械的性質

に適しています 曲げ, ローリング, そして形成
-
Ideal for thin sheet metal fabrication
3. Aesthetic Rust Finish
-
Forms a uniform orange-brown to dark brown patina
-
Widely used for decorative and architectural purposes
4. メンテナンスの手間がかからない
-
No need for painting or coating in most outdoor environments
-
Long service life with minimal upkeep
