ASTM A414 Grade E Pressure Vessel Steel, Composition Spec Product Information -:- For detailed product information, please contact sales. -: ### **Product Introduction: ASTM A414 / A414M Grade E Pressure Vessel Steel** **1. Overview** ASTM A414 / A414M Grade E is a carbon steel specification for pressure vessel plates that provides enhanced strength and improved properties through killed steel practice and grain refinement. As one of the higher-strength grades in the A414 standard family, Grade E offers superior mechanical properties while maintaining good weldability and formability for demanding pressure vessel applications. **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:** P275GH/P295GH (European equivalents with similar application range) * **JIS G3115:** SB410 (Japanese equivalent for pressure vessel use) * **GB 713:** Q245R (Chinese pressure vessel steel equivalent) **3. Chemical Composition (Weight %)** The chemical composition is carefully controlled to achieve enhanced mechanical properties through killed steel practice: | 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 (killed steel) | | **Additional Requirements** | **Fully killed steel, fine austenitic grain practice** | *Note: Grade E requires killed steel practice with a fine austenitic grain size, which provides improved toughness and more consistent mechanical properties.* **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 E is suitable for various pressure vessel applications requiring enhanced properties: * **Medium to High-Pressure Vessels:** Pressure containers for industrial processes * **Process Equipment:** Chemical and petrochemical processing vessels * **Heat Exchangers:** Shells and pressure chambers * **Storage Tanks:** Gas and liquid storage vessels * **Boiler Components:** Pressure parts in industrial boiler systems **6. Key Characteristics & Advantages** * **Enhanced Strength:** Superior mechanical properties through killed steel practice * **Improved Toughness:** Fine grain structure provides better fracture resistance * **Consistent Properties:** Killed steel practice ensures uniform mechanical properties * **Good Weldability:** Suitable for standard welding procedures with proper precautions * **Cost-Effective:** Provides enhanced properties without alloy steel costs **7. Fabrication Considerations** * Supplied in killed steel condition with fine austenitic grain size * Pre-heating recommended for welding operations * Post-weld heat treatment often required * Good formability within standard bending practices * Requires controlled welding parameters due to killed steel characteristics ASTM A414 Grade E represents an enhanced carbon steel option for pressure vessels, providing designers with improved mechanical properties and consistency through killed steel practice while maintaining good fabricability for demanding pressure containment applications. -:- For detailed product information, please contact sales. -: ASTM A414 Grade E Pressure Vessel Steel, Composition Spec Specification Dimensions Size： Diameter 20-1000 mm Length <4384 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 E Pressure Vessel Steel, Composition Spec Properties -:- For detailed product information, please contact sales. -:
