ASTM A242 Corten Steel
ASTM A242 Corten Steel Product Information
ASTM A242 weathering steel is specifically engineered to withstand harsh environmental exposure while maintaining structural integrity. Its unique alloy composition promotes the formation of an adherent, self-renewing patina that acts as a natural barrier against moisture and oxidation. Unlike conventional steel, A242 requires no protective coatings, reducing maintenance costs and environmental impact. Available in sheets, plates, and custom-cut profiles, this material is perfect for architectural cladding, structural frameworks, and artistic installations. Its excellent weldability and formability ensure seamless integration into diverse construction and design projects.
ASTM A242 Corten Steel Chemical Composition
| Element | Standard Range | Key Function |
|---|---|---|
| Carbon (C) | ≤0.15% | Controls strength and weldability |
| Manganese (Mn) | 0.75-1.25% | Enhances hardenability and strength |
| Phosphorus (P) | 0.07-0.15% | Accelerates protective patina formation |
| Sulfur (S) | ≤0.05% | (Lower = better weldability) |
| Silicon (Si) | 0.25-0.75% | Deoxidizer, improves atmospheric resistance |
| Copper (Cu) | 0.25-0.55% | Critical for corrosion resistance |
| Chromium (Cr) | 0.50-1.25% | Forms stable oxide layer |
| Nickel (Ni) | ≤0.65% | Optional addition for toughness |
Key Features:
High Cu+Cr Content - Creates superior protective rust layer vs. standard steel
Controlled P - Optimizes patina speed without compromising ductility
Low C - Ensures excellent weldability (CE typically <0.40)
