ASTM A463 Aluminum-Coated Steel, Type I, Drawing Quality Product Information -:- For detailed product information, please contact sales. -: ### **Product Introduction: ASTM A463 Aluminum-Coated Steel, Type I, Drawing Quality** **1. Overview** ASTM A463 Type I Drawing Quality represents a premium grade of hot-dip aluminum-coated steel sheet specifically engineered for severe forming and deep drawing applications. This product combines the exceptional corrosion and heat resistance of aluminum coating with the superior formability of drawing-quality steel base metal, making it ideal for complex fabricated components requiring both durability and precise forming capabilities. **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 aluminum-silicon coating * **Quality Designation:** **Drawing Quality** - Optimized for severe forming operations * **International Equivalents:** * **EN 10214:** S250GD+AZ (European Aluzinc coated steel equivalent) * **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 (Drawing Quality):** | Element | Composition (%) | | :---------------- | :---------------------------------- | | Carbon (C), max | 0.08 | | Manganese (Mn), max | 0.50 | | Phosphorus (P), max | 0.020 | | Sulfur (S), max | 0.030 | | **Coating Composition** | **Aluminum-silicon alloy (typically 5-11% Si)** | *Note: The low carbon and controlled residual elements ensure excellent deep drawing characteristics and minimize aging effects.* **4. Mechanical & Physical Properties** **Mechanical Properties (Drawing Quality):** | Property | Value | | :--- | :--- | | Tensile Strength | 270 - 380 MPa (39 - 55 ksi) | | Yield Strength (typical) | 180 - 240 MPa (26 - 35 ksi) | | Elongation in 2 in. (50 mm), (min) | 28% | | **Hardness (typical)** | **~45-65 HRB** | | **Plastic Strain Ratio (r-value)** | **1.4 min (typical)** | | **Strain Hardening Exponent (n-value)** | **0.20 min (typical)** | **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) **5. Product Applications** Type I Drawing Quality is specified for demanding applications requiring complex forming: * **Automotive Components:** Complex exhaust system parts, heat shields, mounting brackets * **Appliance Manufacturing:** Deep-drawn oven cavities, burner caps, complex housings * **HVAC Systems:** Intricate ductwork components, heat exchanger parts * **Industrial Equipment:** Deep-drawn containers, complex fabricated assemblies * **Electrical Components:** Transformer cases, electrical enclosures **6. Key Characteristics & Advantages** * **Excellent Deep Drawability:** Specifically designed for severe forming operations * **Superior Surface Quality:** Optimal for painted or unpainted finished products * **Consistent Mechanical Properties:** Guaranteed formability parameters (r-value, n-value) * **Heat Resistance:** Maintains integrity at temperatures up to 510°C * **Corrosion Protection:** Aluminum coating provides 3-5x better protection than galvanized * **Non-aging Characteristics:** Maintains formability over time **7. Fabrication Considerations** * **Deep Drawing:** Excellent performance in deep drawing operations with proper tooling * **Stamping:** Suitable for complex stamping operations * **Welding:** Requires adjusted parameters for spot and seam welding * **Surface Treatment:** May require special pretreatment for painting * **Tooling Design:** Standard tooling applicable with proper clearance allowances **8. Quality Assurance** * Strict chemical composition controls * Mechanical property verification including r-value and n-value testing * Coating weight and uniformity checks * Surface quality inspection for drawing applications * Formability testing per customer requirements ASTM A463 Type I Drawing Quality aluminum-coated steel provides manufacturers with a formable yet durable material solution for applications demanding both complex fabrication capabilities and long-term performance in challenging environmental conditions. -:- For detailed product information, please contact sales. -: ASTM A463 Aluminum-Coated Steel, Type I, Drawing Quality Specification Dimensions Size： Diameter 20-1000 mm Length <4393 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, Drawing Quality Properties -:- For detailed product information, please contact sales. -:
