ASTM A414 Grade C Pressure Vessel Steel, Composition Spec Product Information -:- For detailed product information, please contact sales. -: ### **Product Introduction: ASTM A414 / A414M Grade C Pressure Vessel Steel** **1. Overview** ASTM A414 / A414M Grade C is a carbon steel specification for pressure vessel plates offering higher strength characteristics within the A414 standard family. Positioned between Grades B and D, Grade C provides an excellent balance of enhanced mechanical properties and good fabrication characteristics, making it suitable for moderate to high-pressure applications where increased strength is required without resorting to more expensive alloy steels. **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 (Close European equivalent) * **JIS G3115:** SB410 (Japanese equivalent) * **GB 713:** Q245R (Chinese equivalent with similar application range) **3. Chemical Composition (Weight %)** The chemical composition is controlled to achieve higher strength while maintaining adequate weldability: | Element | Composition (%) | | :---------------- | :---------------------------------- | | Carbon (C), max | 0.27 | | Manganese (Mn), max | 0.90 | | Phosphorus (P), max | 0.025 | | Sulfur (S), max | 0.025 | | Silicon (Si) | 0.15 - 0.40 | *Note: The higher carbon and manganese content compared to Grades A and B provides the increased strength characteristics of Grade C.* **4. Mechanical & Physical Properties** **Mechanical Properties (at room temperature):** | Property | Value | | :--- | :--- | | Tensile Strength | 455 - 530 MPa (66 - 77 ksi) | | Yield Strength (min) | 240 MPa (35 ksi) | | Elongation in 2 in. (50 mm), (min) | 23% | **Physical Properties:** * **Density:** 7.85 g/cm³ (0.284 lb/in³) * **Modulus of Elasticity:** 200 GPa (29 × 10⁶ psi) * **Thermal Conductivity:** ~48.0 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 C is employed in various pressure vessel applications requiring higher strength: * **Medium-Pressure Vessels:** Pressure containers for industrial gases * **Process Reactors:** Chemical processing equipment * **Heat Exchanger Shells:** High-pressure heat exchange equipment * **Storage Vessels:** Compressed gas storage tanks * **Boiler Components:** Pressure parts in boiler systems **6. Key Characteristics & Advantages** * **Higher Strength:** Superior mechanical properties compared to Grades A and B * **Good Weldability:** Can be welded using standard procedures with proper precautions * **Cost-Effective Strength:** Provides higher strength without the cost of alloy steels * **Established Performance:** Proven reliability in pressure containment service * **Good Toughness:** Adequate fracture resistance for most pressure vessel applications **7. Fabrication Considerations** * Typically supplied in as-rolled or normalized condition * Pre-heat may be required for welding depending on thickness and conditions * Post-weld heat treatment recommended for thicker sections * Good formability within standard bending radii for the grade ASTM A414 Grade C serves as an economical intermediate-strength carbon steel for pressure vessels, offering designers a viable option between lower-strength carbon steels and more expensive alloy grades, while maintaining good fabricability and reliable performance in service. -:- For detailed product information, please contact sales. -: ASTM A414 Grade C Pressure Vessel Steel, Composition Spec Specification Dimensions Size： Diameter 20-1000 mm Length <4382 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 C Pressure Vessel Steel, Composition Spec Properties -:- For detailed product information, please contact sales. -:
