ASTM A414 Grade F Pressure Vessel Steel, Composition Spec Product Information -:- For detailed product information, please contact sales. -: ### **Product Introduction: ASTM A414 / A414M Grade F Pressure Vessel Steel** **1. Overview** ASTM A414 / A414M Grade F is a carbon-manganese-silicon steel specification for pressure vessel plates that provides enhanced strength characteristics through optimized chemical composition and processing. As one of the higher-strength grades in the A414 standard series, Grade F offers an economical solution for pressure vessel applications requiring superior mechanical properties while maintaining good weldability and formability. **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 mechanical properties) * **JIS G3115:** SB410 (Japanese pressure vessel steel standard) * **GB 713:** Q245R/Q345R (Chinese pressure vessel steel equivalents) **3. Chemical Composition (Weight %)** The chemical composition is carefully balanced to achieve enhanced mechanical properties while maintaining good fabricability: | 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 | | **Additional Notes** | **Killed steel, fine grain practice typically specified** | *Note: Grade F typically requires killed steel practice with fine grain size to ensure consistent mechanical properties and improved toughness.* **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:** ~46.5 W/m·K (at 100°C) * **Coefficient of Thermal Expansion:** ~11.8 × 10⁻⁶/K (20-100°C) * **Specific Heat Capacity:** ~450 J/kg·K **5. Product Applications** ASTM A414 Grade F is suitable for various pressure vessel applications requiring enhanced mechanical properties: * **Medium to High-Pressure Vessels:** Industrial pressure containers * **Process Reactors:** Chemical and petrochemical processing equipment * **Heat Exchanger Shells:** High-pressure heat exchange equipment * **Storage Vessels:** Compressed gas and liquid storage tanks * **Boiler Components:** Pressure parts in industrial boiler systems * **Industrial Gas Equipment:** Oxygen, nitrogen, and other gas containment vessels **6. Key Characteristics & Advantages** * **Enhanced Strength:** Superior mechanical properties compared to lower A414 grades * **Good Toughness:** Fine grain structure provides adequate fracture resistance * **Cost-Effective:** Provides higher strength without alloy steel costs * **Established Reliability:** Proven performance in pressure containment service * **Good Weldability:** Can be welded using standard procedures with proper precautions * **Consistent Properties:** Killed steel practice ensures uniform mechanical behavior **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 * Requires careful control of welding parameters and procedures ASTM A414 Grade F represents a cost-effective high-strength carbon steel option for pressure vessels, providing designers with enhanced mechanical properties while maintaining good fabricability for demanding pressure containment applications across various industrial sectors. -:- For detailed product information, please contact sales. -: ASTM A414 Grade F Pressure Vessel Steel, Composition Spec Specification Dimensions Size： Diameter 20-1000 mm Length <4385 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 F Pressure Vessel Steel, Composition Spec Properties -:- For detailed product information, please contact sales. -:
