Corten A Weathering Steel Plate, also commonly known as weathering steel or atmospheric corrosion steel, is a special steel that improves its corrosion resistance in the atmospheric environment by adding specific alloy elements (such as copper, phosphorus, chromium, nickel, etc.).
1. High strength: Corten A steel has high tensile strength and yield strength, suitable for various structural parts.
2. Excellent corrosion resistance: In the natural environment, Corten A steel can resist atmospheric corrosion, reducing the frequency of maintenance and replacement.
3. Unique appearance: Over time, a stable rust-red oxide layer will form on the surface of Corten A steel, giving it a unique visual effect.
Corten A Weathering Steel Plate is a high-strength, low-alloy steel with excellent weathering properties and a unique appearance. This kind of steel forms a protective rust layer by adding small amounts of copper, nickel, chromium and other elements to the steel, making it resistant to corrosion when exposed to the atmospheric environment.
characteristic:
Weather resistance: The distinctive feature of Corten A steel plate is its ability to form a dense oxidation rust layer when exposed to the atmospheric environment. This layer of rust prevents further corrosion, extending the life of the steel.
High Strength: Compared to ordinary carbon steel, Corten A has higher yield strength and tensile strength.
Low maintenance: Due to its excellent weather resistance, Corten A reduces the need for coatings and other protective measures, lowering maintenance costs.
Beauty: After the rust layer is formed, the surface of the steel plate shows a unique bronze or reddish brown color, which is often used in architecture and art design to provide natural and industrial beauty.
The typical chemical composition of Corten A steel plates is as follows:
Carbon (C): ≤ 0.12%
Silicon (Si): 0.25 – 0.75%
Manganese (Mn): 0.20 – 0.50%
Phosphorus (P): 0.07 – 0.15%
Sulfur (S): ≤ 0.030%
Chromium (Cr): 0.30 – 1.25%
Copper (Cu): 0.25 – 0.55%
Nickel (Ni): ≤ 0.65%
Mechanical properties:
Yield strength: ≥ 345 MPa
Tensile strength: 480 – 630 MPa
Elongation: 20% (on 2-inch [50mm] specimens)
Corten A Weathering Steel Plate is widely used in the fields of architecture, bridges, sculptures, landscape art, etc. In the field of architecture, it is often used to make structural parts such as exterior wall panels, roof panels, canopies, etc. It not only has excellent corrosion resistance, but also gives the building a unique visual effect. In the field of bridges, the high strength and corrosion resistance of Corten A steel make it an ideal choice for bridge construction. In addition, due to its unique appearance and weather resistance, Corten A steel is also widely used in sculptures and landscape art.
