ASTM A285, Grade B Product Information -:- For detailed product information, please contact sales. -: ### **Product Datasheet: ASTM A285 Grade B Pressure Vessel Quality Carbon Steel Plate** #### **1. Product Overview** ASTM A285 Grade B is a low to intermediate tensile strength carbon steel plate specifically designed for moderate-service pressure vessels and structural components. It serves as a balanced intermediate option between the lower-strength Grade A and higher-strength Grade C within the A285 specification. This grade provides improved strength over Grade A while maintaining good formability and weldability, making it suitable for a wide range of industrial applications involving pressure containment. **Key Advantages:** - **Cost-Effective Performance:** Optimal balance of strength and cost for moderate pressure applications - **Excellent Fabricability:** Demonstrates good formability for rolling and pressing operations - **Reliable Weldability:** Readily weldable using standard procedures with minimal preheating requirements - **Proven Track Record:** Extensive history of successful use in pressure vessel construction --- #### **2. International Standard** This product is manufactured and tested in accordance with the latest version of: - **ASTM A285/A285M:** Standard Specification for Pressure Vessel Plates, Carbon Steel, Low- and Intermediate-Tensile Strength The material is also approved for ASME Boiler and Pressure Vessel Code applications under specification **SA-285**. --- #### **3. Chemical Composition (Ladle Analysis, %)** The chemical composition is carefully controlled to ensure consistent mechanical properties and performance characteristics. | Element | Composition (%) | |---------|-----------------| | Carbon (C), max | 0.22 | | Manganese (Mn), max | 0.90 | | Phosphorus (P), max | 0.035 | | Sulfur (S), max | 0.04 | | Silicon (Si) | ≤ 0.40 | *Note: Silicon content is typically controlled to ensure proper deoxidation practice.* --- #### **4. Mechanical Properties** Mechanical properties are guaranteed through standardized testing procedures. | Property | Value | Unit | |----------|-------|------| | **Tensile Strength** | 345-450 | MPa (50-65 ksi) | | **Yield Strength, min** | 185 | MPa (27 ksi) | | **Elongation in 2" (50 mm), min** | 27 | % | *Note: Elongation requirements may vary based on plate thickness. Values shown represent typical requirements.* --- #### **5. Physical Properties (Typical Values)** - **Density:** 7.85 g/cm³ (0.284 lb/in³) - **Modulus of Elasticity:** 200 GPa (29,000 ksi) - **Poisson's Ratio:** 0.29 - **Thermal Conductivity:** 51.9 W/m·K (at 100°C) - **Coefficient of Thermal Expansion:** 11.5 × 10⁻⁶/°C (20-100°C) --- #### **6. Product Applications** ASTM A285 Grade B is widely used in pressure vessel fabrication and other industrial equipment requiring reliable performance under moderate service conditions. **Primary Applications Include:** - **Pressure Vessels:** Storage tanks, air receivers, and process vessels - **Heat Exchangers:** Shells and channel components - **Boiler Components:** Casing and structural elements - **Water Storage Tanks:** Municipal and industrial water systems - **Industrial Processing Equipment:** Reactors and mixing vessels --- #### **7. Fabrication & Welding Characteristics** **Welding:** - Exhibits excellent weldability using common processes (SMAW, GMAW, SAW) - Low hydrogen welding practices recommended for thicker sections - Preheating generally not required for thinner plates (<25 mm) - Post-weld heat treatment optional based on application requirements **Forming & Machining:** - Good cold forming characteristics for moderate deformation - Readily machinable using conventional methods - Suitable for hot forming operations with appropriate thermal controls --- #### **8. Limitations & Service Considerations** - **Temperature Limit:** Not recommended for prolonged service above 425°C (800°F) - **Impact Requirements:** Charpy V-notch testing not typically specified - **Corrosion Resistance:** Limited inherent corrosion resistance - requires protective coatings for corrosive environments - **Section Size Limitations:** Mechanical properties may vary with plate thickness --- **Disclaimer:** This technical datasheet provides general information for reference purposes only. Specifications and requirements may vary based on specific application needs and the latest edition of the governing standards.
