ASTM A414 Grade D Pressure Vessel Steel, Composition Spec Product Information -:- For detailed product information, please contact sales. -: ### **Product Introduction: ASTM A414 / A414M Grade D Pressure Vessel Steel** **1. Overview** ASTM A414 / A414M Grade D is a carbon steel specification for pressure vessel plates that provides higher strength among the standard A414 grades while maintaining good fabrication characteristics. As one of the stronger grades in the A414 carbon steel family, Grade D offers an economical solution for pressure vessels requiring enhanced mechanical properties without the need for alloy steel compositions. **2. Key International Standards** * **Primary Standard:** **ASTM A414 / A414M** - Standard Specification for Carbon Steel Sheets for Pressure Vessels * **Governing Standard:** **ASTM A20/A20M** - Standard Specification for General Requirements for Steel Plates for Pressure Vessels * **International Equivalents:** * **EN 10028-2:** P295GH (Close European equivalent) * **JIS G3115:** SB410 (Japanese equivalent, similar application range) * **GB 713:** Q245R (Chinese equivalent for pressure vessel applications) **3. Chemical Composition (Weight %)** The chemical composition is balanced to achieve higher strength while maintaining adequate weldability and toughness: | Element | Composition (%) | | :---------------- | :---------------------------------- | | Carbon (C), max | 0.28 | | Manganese (Mn), max | 0.90 | | Phosphorus (P), max | 0.025 | | Sulfur (S), max | 0.025 | | Silicon (Si) | 0.15 - 0.40 | *Note: The controlled carbon and manganese content provides the enhanced strength characteristics while maintaining reasonable weldability with proper procedures.* **4. Mechanical & Physical Properties** **Mechanical Properties (at room temperature):** | Property | Value | | :--- | :--- | | Tensile Strength | 480 - 550 MPa (70 - 80 ksi) | | Yield Strength (min) | 255 MPa (37 ksi) | | Elongation in 2 in. (50 mm), (min) | 21% | **Physical Properties:** * **Density:** 7.85 g/cm³ (0.284 lb/in³) * **Modulus of Elasticity:** 200 GPa (29 × 10⁶ psi) * **Thermal Conductivity:** ~47.0 W/m·K (at 100°C) * **Coefficient of Thermal Expansion:** ~11.8 × 10⁻⁶/K (20-100°C) * **Poisson's Ratio:** 0.29 **5. Product Applications** ASTM A414 Grade D is commonly used in various pressure vessel applications requiring higher strength: * **High-Pressure Vessels:** Containers for industrial gases and processes * **Process Equipment:** Chemical and petrochemical processing vessels * **Heat Exchangers:** Shells and pressure chambers * **Storage Tanks:** High-pressure gas and liquid storage vessels * **Boiler Components:** Pressure parts in industrial boiler systems **6. Key Characteristics & Advantages** * **Enhanced Strength:** Higher mechanical properties compared to Grades A, B, and C * **Cost-Effective:** Provides increased strength without alloy steel costs * **Good Weldability:** Can be welded using standard procedures with proper precautions * **Established Reliability:** Proven performance in pressure containment applications * **Adequate Toughness:** Suitable fracture resistance for pressure vessel service **7. Fabrication Considerations** * Typically supplied in as-rolled or normalized condition * Pre-heating recommended for welding, especially for thicker sections * Post-weld heat treatment often required * Good formability within standard bending practices for the grade * Requires careful control of welding parameters due to higher carbon content ASTM A414 Grade D represents an economical high-strength carbon steel option for pressure vessels, providing designers with enhanced mechanical properties while maintaining reasonable fabricability and reliable performance in demanding service conditions. -:- For detailed product information, please contact sales. -: ASTM A414 Grade D Pressure Vessel Steel, Composition Spec Specification Dimensions Size： Diameter 20-1000 mm Length <4383 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 A414 Grade D Pressure Vessel Steel, Composition Spec Properties -:- For detailed product information, please contact sales. -:
