ASTM A285, Grade C Product Information -:- For detailed product information, please contact sales. -: ### **Product Datasheet: ASTM A285 Grade C Pressure Vessel Quality Carbon Steel Plate** #### **1. Product Overview** ASTM A285 Grade C is a carbon steel plate classified under the standard for pressure vessel plates, specifically designed for low and intermediate temperature service. As the highest strength grade within the A285 specification, it provides enhanced load-bearing capacity while maintaining good fabrication characteristics. This grade is particularly suitable for welded pressure vessels where higher strength than Grades A and B is required, but the service conditions do not necessitate the use of more expensive alloy steels. **Key Advantages:** - **Enhanced Strength:** Highest tensile and yield strength among A285 grades - **Cost-Effective Solution:** Provides improved mechanical properties without alloying elements - **Good Weldability:** Readily weldable using standard procedures - **Proven Reliability:** Established track record in pressure vessel applications - **Adequate Formability:** Suitable for moderate forming operations --- #### **2. International Standard** This product conforms to the latest edition of: - **ASTM A285/A285M:** Standard Specification for Pressure Vessel Plates, Carbon Steel, Low- and Intermediate-Tensile Strength The material is approved for ASME Boiler and Pressure Vessel Code applications under specification **SA-285 Grade C**. --- #### **3. Chemical Composition (Heat Analysis, %)** The chemical composition is controlled to achieve the specified mechanical properties while maintaining good weldability and formability. | Element | Composition (%) | |---------|-----------------| | Carbon (C), max | 0.28 | | Manganese (Mn), max | 0.90 | | Phosphorus (P), max | 0.035 | | Sulfur (S), max | 0.04 | | Silicon (Si) | 0.15-0.40 | *Note: Silicon content is controlled to ensure killed steel practice for improved soundness.* --- #### **4. Mechanical Properties** Mechanical properties are guaranteed through standardized testing of the plate material. | Property | Value | Unit | |----------|-------|------| | **Tensile Strength** | 380-515 | MPa (55-75 ksi) | | **Yield Strength, min** | 205 | MPa (30 ksi) | | **Elongation in 2" (50 mm), min** | 25 | % | *Note: Mechanical properties may vary with plate thickness. The 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) - **Specific Heat Capacity:** 486 J/kg·K (at 100°C) - **Coefficient of Thermal Expansion:** 11.5 × 10⁻⁶/°C (20-100°C) --- #### **6. Product Applications** ASTM A285 Grade C is widely used in pressure vessel construction and other industrial applications requiring reliable performance under moderate pressure conditions. **Primary Applications Include:** - **Pressure Vessels:** Storage tanks, air receivers, and industrial containers - **Heat Exchangers:** Shells and supporting structures - **Boiler Components:** Casing and non-critical pressure parts - **Water Treatment Equipment:** Pressure vessels and tanks - **Industrial Processing Vessels:** Reactors and mixing containers - **Compressed Air Systems:** Receivers and storage tanks --- #### **7. Fabrication & Welding Characteristics** **Welding Performance:** - Good weldability using common processes (SMAW, GMAW, FCAW, SAW) - Preheating recommended for thicker sections and restrained joints - Low hydrogen welding practices advised for optimal results - Post-weld heat treatment may be beneficial for stress relief **Forming & Machining:** - Suitable for cold forming with moderate deformation - Hot forming operations require controlled procedures - Good machinability with conventional tooling - Forming limitations should be considered for complex shapes --- #### **8. Service Limitations & Considerations** - **Temperature Service Limit:** Not recommended for prolonged service above 425°C (800°F) - **Impact Properties:** Charpy V-notch testing not typically specified in base standard - **Corrosion Resistance:** Limited inherent corrosion resistance - requires protection in corrosive environments - **Section Size Effects:** Mechanical properties may decrease with increasing plate thickness - **Notch Sensitivity:** Moderate notch sensitivity requires proper design practices --- #### **9. Quality Assurance** - **Manufacturing Process:** Produced to killed steel practice - **Testing Requirements:** Includes tension tests and chemical analysis - **Surface Quality:** Free from injurious defects - **Repair:** Weld repair permitted following qualified procedures --- **Disclaimer:** This technical datasheet provides general information for reference purposes only.
