ASTM A529 Steel Product Information -:- For detailed product information, please contact sales. -: ### **Product Introduction: ASTM A529 Structural Steel** **ASTM A529** is a standard specification for high-strength carbon-manganese steel plates, shapes, and bars of structural quality, primarily used in riveted, bolted, or welded construction of bridges and buildings. This grade provides a minimum yield strength of **50 ksi (345 MPa)**, offering an economical alternative to traditional carbon steels with enhanced strength characteristics. As a cost-effective high-strength material, it serves as an intermediate option between conventional mild steels and premium high-strength low-alloy (HSLA) steels. --- #### **1. International Standards & Grades** **Primary Standard:** **ASTM A529/A529M** - "Standard Specification for High-Strength Carbon-Manganese Steel of Structural Quality" **Grade Classification:** - **Grade 50** [345 MPa] - Standard grade - **Grade 55** [380 MPa] - Higher strength variant (subject to agreement between supplier and purchaser) **International Equivalents:** - **EN 10025-2**: S275J0/J2 - **JIS G3101**: SM490 - **ISO 630-2**: E275C --- #### **2. Chemical Composition** The chemical composition requirements for ASTM A529 Grade 50: | Element | Composition (Maximum %) | |---|---| | Carbon (C) | 0.27 | | Manganese (Mn) | 1.20 | | Phosphorus (P) | 0.04 | | Sulfur (S) | 0.05 | | Silicon (Si) | 0.40 | | Copper (Cu) | 0.20 (when copper steel is specified) | **Key Composition Features:** - **Carbon-Manganese System**: Relies on manganese for solid solution strengthening - **Moderate Carbon Content**: Balances strength and weldability - **Simple Chemistry**: No expensive alloying elements, making it cost-effective - **Optional Copper**: Provides improved atmospheric corrosion resistance when specified --- #### **3. Physical & Mechanical Properties** **Mechanical Properties (Grade 50):** | Property | Value | |---|---| | **Tensile Strength** | 415-585 MPa (60-85 ksi) | | **Yield Strength (min.)** | 345 MPa (50 ksi) | | **Elongation in 2" (min.)** | 18% | | **Elongation in 8" (min.)** | 21% | **Physical Properties:** - **Density**: 7.85 g/cm³ (0.284 lb/in³) - **Modulus of Elasticity**: 200 GPa (29,000 ksi) - **Poisson's Ratio**: 0.29 - **Coefficient of Thermal Expansion**: 11.5 × 10⁻⁶/°C (20-100°C) **Impact Properties:** - Charpy V-Notch testing typically conducted at 70°F (21°C) - Minimum average impact energy: 20 ft-lbf (27 J) --- #### **4. Product Applications** **Building Construction:** - Structural frames and columns - Roof trusses and support systems - Building frameworks - Industrial facility structures **Bridge Construction:** - Secondary bridge members - Approach spans - Pedestrian bridge components - Bridge deck supports **General Structural Applications:** - Transmission towers - Construction equipment components - Heavy-duty storage racks - Industrial platform structures **Transportation Infrastructure:** - Highway sign supports - Guard rail components - Traffic signal structures **Marine Structures:** - Pier and dock components - Marine platform supports - Coastal structure elements --- #### **5. Fabrication Characteristics** **Welding:** - **Excellent Weldability**: Can be welded by all common processes - **Preheat Requirements**: Generally not required for thinner sections - **Recommended Processes**: SMAW, GMAW, FCAW, SAW - **Filler Metals**: E70XX series electrodes or equivalent **Forming & Machining:** - **Cold Forming**: Good formability with standard equipment - **Bend Radius**: Typically 1.5t to 2t for 90° bends - **Machinability**: Good (approximately 60% of B1112 steel) - **Cutting Methods**: All standard methods including oxy-fuel, plasma, and shear cutting **Heat Treatment:** - Normally supplied in as-rolled condition - Stress relieving available when specified - No quenching and tempering required --- ### **Technical Summary** ASTM A529 represents an economical high-strength structural steel that bridges the gap between conventional carbon steels and more expensive HSLA grades. Its simple carbon-manganese chemistry provides cost-effective strength enhancement while maintaining good weldability and formability. The grade is particularly valuable in applications where the higher strength of 50 ksi yield strength is beneficial, but the premium cost of alloy steels cannot be justified. While it doesn't offer the specialized properties of weathering steels or the ultra-high strength of quenched and tempered grades, ASTM A529 remains a popular choice for general structural applications where reliability and economy are equally important. Its straightforward fabrication characteristics make it suitable for a wide range of construction projects without requiring specialized equipment or procedures. -:- For detailed product information, please contact sales. -: ASTM A529 Steel Specification Dimensions Size： Diameter 20-1000 mm Length <4291 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 A529 Steel Properties -:- For detailed product information, please contact sales. -:
