Overview** ASTM A414 / A414M Grade B is a carbon steel specification for pressure vessel plates offering enhanced strength compared to Grade A while maintaining good weldability and formability. As part of the A414 standard family, Grade B provides an optimal balance between mechanical performance and fabricability, making it a preferred choice for moderate-pressure applications where Grade A's strength is insufficient. **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:** P265GH (Close European equivalent) * **JIS G3115:** SB410 (Japanese equivalent) * **GB 713:** Q245R (Chinese equivalent) **3. Chemical Composition (Weight %)** The chemical composition is carefully balanced to achieve higher strength while maintaining good weldability: | Element | Composition (%) | | :---------------- | :---------------------------------- | | Carbon (C), max | 0.22 | | Manganese (Mn), max | 0.60 (for thickness ≤ 3/4 in. / 19 mm) | | Phosphorus (P), max | 0.025 | | Sulfur (S), max | 0.025 | | Silicon (Si) | 0.15 - 0.40 | *Note: Manganese content may increase to 0.90% for thicker plates. Silicon content is typically specified for killed steel practice.* **4. Mechanical & Physical Properties** **Mechanical Properties (at room temperature):** | Property | Value | | :--- | :--- | | Tensile Strength | 410 - 485 MPa (60 - 70 ksi) | | Yield Strength (min) | 220 MPa (32 ksi) | | Elongation in 2 in. (50 mm), (min) | 25% | **Physical Properties:** * **Density:** 7.85 g/cm³ (0.284 lb/in³) * **Modulus of Elasticity:** 200 GPa (29 × 10⁶ psi) * **Thermal Conductivity:** ~50.0 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 B is widely used in pressure vessel fabrication for various industries: * **Pressure Vessels:** General-purpose pressure containers * **Heat Exchangers:** Shells and chambers * **Storage Tanks:** Compressed air receivers, gas storage vessels * **Boiler Components:** Low to medium pressure boiler parts * **Process Equipment:** Chemical and petrochemical processing vessels **6. Key Characteristics & Advantages** * **Enhanced Strength:** Higher mechanical properties compared to Grade A * **Good Weldability:** Suitable for all conventional welding methods * **Excellent Formability:** Can be cold formed and fabricated easily * **Cost-Effective:** Provides better strength-to-cost ratio than higher alloys * **Reliable Performance:** Proven track record in pressure containment applications **7. Heat Treatment and Fabrication** * Typically supplied in as-rolled or normalized condition * Post-weld heat treatment may be required based on thickness and application * Excellent bending and forming characteristics * Compatible with common welding processes including SMAW, GMAW, and SAW ASTM A414 Grade B represents an optimal solution for pressure vessel applications requiring moderate strength combined with excellent fabrication characteristics, serving as a reliable and economical material choice for various industrial pressure containment systems. -:- For detailed product information, please contact sales. -: ASTM A414 Grade B Pressure Vessel Steel, Composition Spec Specification Dimensions Size： Diameter 20-1000 mm Length <4381 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 B Pressure Vessel Steel, Composition Spec Properties -:- For detailed product information, please contact sales. -:
