ASTM A441 Steel, 19 mm thick Product Information -:- For detailed product information, please contact sales. -: ### **Product Introduction: ASTM A441 High-Strength Low-Alloy Structural Steel (19 mm and thicker)** **1. Overview** ASTM A441 is a specification for high-strength low-alloy structural steel plates, bars, and shapes with thicknesses of 19 mm (3/4 inch) and greater. This manganese-vanadium steel provides enhanced strength and atmospheric corrosion resistance compared to carbon structural steels, making it suitable for welded, bolted, or riveted structures requiring improved mechanical properties and durability. **2. Key International Standards** * **Primary Standard:** **ASTM A441/A441M** - Standard Specification for High-Strength Low-Alloy Structural Manganese Vanadium Steel * **Governing Standard:** **ASTM A6/A6M** - Standard Specification for General Requirements for Rolled Structural Steel Bars, Plates, Shapes, and Sheet Piling * **International Equivalents:** * **EN 10025:** S355J0/J2 (European structural steel equivalent) * **JIS G3106:** SM490YA (Japanese high-strength steel) * **GB/T 1591:** Q345 (Chinese high-strength low-alloy structural steel) * **CAN/CSA G40.21:** 350W (Canadian structural steel) **3. Chemical Composition (Weight %)** The chemical composition includes vanadium for grain refinement and strength enhancement: | Element | Composition (%) | | :---------------- | :---------------------------------- | | Carbon (C), max | 0.22 | | Manganese (Mn) | 0.85 - 1.25 | | Phosphorus (P), max | 0.04 | | Sulfur (S), max | 0.05 | | Silicon (Si) | 0.15 - 0.30 | | Vanadium (V) | 0.02 - 0.10 | | Copper (Cu), min | 0.20 (when specified for corrosion resistance) | *Note: Vanadium contributes to grain refinement and precipitation strengthening, while copper enhances atmospheric corrosion resistance.* **4. Mechanical & Physical Properties** **Mechanical Properties (for thicknesses 19-65 mm):** | Property | Value | | :--- | :--- | | Tensile Strength | 480 MPa min (70 ksi min) | | Yield Strength | 345 MPa min (50 ksi min) | | Elongation in 2 in. (50 mm), (min) | 18% | | **Hardness (typical)** | **~170-210 HB** | **Physical Properties:** * **Density:** 7.85 g/cm³ (0.284 lb/in³) * **Modulus of Elasticity:** 200 GPa (29 × 10⁶ psi) * **Thermal Conductivity:** ~47.5 W/m·K (at 100°C) * **Coefficient of Thermal Expansion:** ~11.7 × 10⁻⁶/K (20-100°C) * **Poisson's Ratio:** 0.29 **5. Product Applications** ASTM A441 steel is widely used in heavy structural applications requiring high strength and durability: * **Bridge Construction:** Main girders, trusses, and support structures * **Building Frameworks:** High-rise building frames and columns * **Heavy Equipment:** Crane booms, excavator frames, mining equipment * **Transmission Towers:** Heavy-duty electrical transmission structures * **Industrial Structures:** Plant frameworks, support structures * **Transportation Equipment:** Truck frames and trailer components **6. Key Characteristics & Advantages** * **Enhanced Strength:** Higher yield and tensile strength compared to carbon steels * **Improved Toughness:** Good impact resistance at service temperatures * **Atmospheric Corrosion Resistance:** 2-4 times better than carbon steel when copper-bearing * **Good Weldability:** Suitable for all conventional welding methods * **Vanadium Strengthening:** Precipitation strengthening provides consistent properties * **Cost-Effective:** Optimal strength-to-cost ratio for structural applications **7. Fabrication Considerations** * **Welding:** Requires proper procedures including pre-heating for thicker sections * **Forming:** Good formability with recommended bending radii * **Machining:** Good machinability in annealed condition * **Heat Treatment:** Typically used in as-rolled condition * **Surface Protection:** Requires protective coatings for maximum service life **Note:** ASTM A441 has been largely superseded by ASTM A572 Grade 50 for most applications, but remains important for existing structures and specific applications requiring its particular properties. ASTM A441 represents an important high-strength low-alloy structural steel option, providing reliable performance in demanding structural applications where enhanced strength and durability are required. -:- For detailed product information, please contact sales. -: ASTM A441 Steel, 19 mm thick Specification Dimensions Size： Diameter 20-1000 mm Length <4388 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 A441 Steel, 19 mm thick Properties -:- For detailed product information, please contact sales. -:
