ASTM A414 Grade A Pressure Vessel Steel, Composition Spec Product Information -:- For detailed product information, please contact sales. -: ### **Product Introduction: ASTM A414 / A414M Grade A Pressure Vessel Steel** **1. Overview** ASTM A414 / A414M Grade A is a standard specification for carbon steel plates intended for the fabrication of pressure vessels. This grade belongs to a family of steels specifically designed for applications where reliability and safety are paramount. Grade A is characterized by its good weldability, formability, and moderate strength, making it a cost-effective choice for a wide range of low to moderate-pressure containment applications. **2. Key International Standards** * **Primary Standard:** **ASTM A414 / A414M** - Standard Specification for Carbon Steel Sheets for Pressure Vessels. * This standard covers several grades (A, B, C, D, E, F, G) with Grade A being a common, general-purpose option. * **Related Standards:** * **ASTM A20/A20M:** Standard Specification for General Requirements for Steel Plates for Pressure Vessels. This provides supplementary requirements for testing, inspection, and documentation. * **Common Equivalent Standards:** * **EN 10028-2:** P235GH (This European standard is a very close equivalent in terms of composition and mechanical properties). * **JIS G3115:** SB410 (Japanese standard for steel for pressure vessels). **3. Chemical Composition (Weight %)** The chemical composition for ASTM A414 Grade A is carefully controlled to ensure good weldability and toughness. The following represents the typical ladle analysis requirements: | Element | Composition (%) | | :---------------- | :---------------------------------- | | Carbon (C), max | 0.18 | | 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 (killed steel, by agreement) | *Note:* The manganese limit may increase to 0.90% for thicker plates, as specified in the standard. The silicon content is typically required for killed (deoxidized) steel to ensure soundness. **4. Mechanical & Physical Properties** The mechanical properties are guaranteed in the as-rolled or normalized condition, depending on the thickness and processing. **Mechanical Properties (at room temperature):** | Property | Value | | :--- | :--- | | Tensile Strength | 380 - 450 MPa (55 - 65 ksi) | | Yield Strength (min) | 205 MPa (30 ksi) | | Elongation in 2 in. (50 mm), (min) | 27% | **Approximate Physical Properties:** * **Density:** 7.85 g/cm³ (0.284 lb/in³) * **Melting Point:** ~ 1425 - 1520 °C (2600 - 2770 °F) * **Modulus of Elasticity:** 200 GPa (29 x 10⁶ psi) * **Thermal Conductivity:** ~ 51.9 W/m·K (at 100°C) * **Coefficient of Thermal Expansion:** ~ 11.5 x 10⁻⁶ /K (20-100°C) *Note: Physical properties are approximate and can vary.* **5. Product Applications** ASTM A414 Grade A is widely used in the construction of pressure vessels and components for various industries. Its primary applications include: * **Air Receivers:** Tanks for storing compressed air in industrial systems. * **Hot Water Storage Tanks:** Boilers and tanks for heating and plumbing systems. * **Low-Pressure Boilers:** Vessels for steam generation and heating. * **Oil and Gas:** Tanks for storing crude oil, fuel, and other petroleum products at low pressures. * **Chemical Industry:** Tanks and vessels for storing non-corrosive or mildly corrosive chemicals. **6. Key Characteristics & Advantages** * **Excellent Weldability:** The low carbon content minimizes the risk of cracking during welding, making fabrication straightforward. * **Good Formability:** Can be easily rolled, bent, and formed into the required shapes for vessel construction. * **Cost-Effectiveness:** Provides a reliable and economical solution for many standard pressure vessel applications. * **Adequate Strength:** Offers sufficient strength for a wide range of low to moderate-pressure services. In summary, **ASTM A414 Grade A** is a versatile and widely used carbon steel for pressure vessels. Its balanced properties of strength, weldability, and formability make it a fundamental material for fabricating safe and reliable containment equipment across numerous industrial sectors. -:- For detailed product information, please contact sales. -: ASTM A414 Grade A Pressure Vessel Steel, Composition Spec Specification Dimensions Size： Diameter 20-1000 mm Length <4380 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 A Pressure Vessel Steel, Composition Spec Properties -:- For detailed product information, please contact sales. -:
