ASTM A463 Aluminum-Coated Steel, Type I, Commercial Quality Product Information -:- For detailed product information, please contact sales. -: ### **Product Introduction: ASTM A463 Aluminum-Coated Steel, Type I, Commercial Quality** **1. Overview** ASTM A463 Type I Commercial Quality is a specification for steel sheets coated with aluminum using the hot-dip process, providing excellent corrosion resistance and heat reflectivity. This product combines the strength of steel with the protective qualities of aluminum, offering superior performance in high-temperature and corrosive environments compared to standard galvanized steel. **2. Key International Standards** * **Primary Standard:** **ASTM A463/A463M** - Standard Specification for Steel Sheet, Aluminum-Coated, by the Hot-Dip Process * **Coating Type:** **Type I** - Regular coating (commercial coating weight) * **Quality Designation:** **Commercial Quality** - For forming and moderate bending applications * **International Equivalents:** * **EN 10214:** S250GD+AZ (European equivalent for Aluzinc coated steel) * **JIS G3314:** SASH (Japanese aluminum-coated steel sheet) * **GB/T 14978:** LXXXAZ (Chinese aluminum-zinc alloy coated steel) **3. Chemical Composition (Weight %)** **Base Steel Composition (Commercial Quality):** | Element | Composition (%) | | :---------------- | :---------------------------------- | | Carbon (C), max | 0.15 | | Manganese (Mn), max | 0.60 | | Phosphorus (P), max | 0.035 | | Sulfur (S), max | 0.040 | | **Coating Composition** | **Aluminum-silicon alloy (typically 5-11% Si)** | *Note: The aluminum-silicon coating composition prevents brittle iron-aluminum intermetallic formation and improves coating adhesion.* **4. Mechanical & Physical Properties** **Mechanical Properties (Commercial Quality):** | Property | Value | | :--- | :--- | | Tensile Strength | 310 - 480 MPa (45 - 70 ksi) | | Yield Strength (min) | 230 MPa (33 ksi) | | Elongation in 2 in. (50 mm), (min) | 20% | **Physical Properties:** * **Coating Weight:** 0.035-0.045 oz/ft² (100-130 g/m²) per side * **Maximum Service Temperature:** 510°C (950°F) * **Thermal Reflectivity:** ~80% (at 500°C) * **Density:** 7.8 g/cm³ (coated product) * **Coating Thickness:** 25-35 μm per side **5. Product Applications** ASTM A463 Type I Commercial Quality is widely used in applications requiring heat resistance and corrosion protection: * **Heat Exchangers:** Automotive exhaust systems, heat shields * **Appliance Industry:** Oven liners, dryer drums, heater housings * **Building & Construction:** Roofing, siding, architectural panels * **Industrial Equipment:** Furnace parts, thermal processing equipment * **Agricultural Equipment:** Grain bins, silos, storage containers * **Electrical Enclosures:** Transformer cases, electrical boxes **6. Key Characteristics & Advantages** * **Excellent Heat Resistance:** Withstands temperatures up to 510°C without significant degradation * **Superior Corrosion Protection:** 3-5 times better corrosion resistance than galvanized steel * **Good Formability:** Suitable for moderate bending and forming operations * **Heat Reflectivity:** High thermal reflectivity reduces heat absorption * **Sulfidation Resistance:** Excellent resistance to sulfur compounds at high temperatures * **Atmospheric Durability:** Performs well in industrial and marine environments **7. Fabrication Considerations** * **Forming:** Can be formed using standard equipment; tighter bend radii may be required * **Welding:** Spot welding and seam welding possible with adjusted parameters * **Cutting:** All conventional cutting methods applicable * **Joining:** Mechanical fastening recommended for critical applications * **Surface Treatment:** Paint adhesion requires special surface preparation **8. Quality Assurance** * Coating weight verification per standard requirements * Adherence testing (bend tests) * Surface quality inspection * Dimensional tolerance verification ASTM A463 Type I Commercial Quality aluminum-coated steel provides an optimal balance of corrosion resistance, heat reflectivity, and formability, making it a preferred choice for applications where both durability and thermal performance are critical requirements. -:- For detailed product information, please contact sales. -: ASTM A463 Aluminum-Coated Steel, Type I, Commercial Quality Specification Dimensions Size： Diameter 20-1000 mm Length <4392 mm Size:We can customized as required Standard： Per your request or drawing We can customized as required Properties（Theoretical） Chemical Composition -:- For detailed product information, please contact sales. -: ASTM A463 Aluminum-Coated Steel, Type I, Commercial Quality Properties -:- For detailed product information, please contact sales. -:
