ASTM A514 Steel, grade M, plate thickness 19-64 mm Product Information -:- For detailed product information, please contact sales. -: ### **Product Introduction: ASTM A514 Grade M Steel Plate (Thickness 19-64 mm)** **ASTM A514 Grade M** is a high-strength, quenched and tempered alloy steel plate engineered to deliver exceptional mechanical properties in intermediate to heavy sections. As part of the A514 specification, Grade M maintains the characteristic 100 ksi (690 MPa) minimum yield strength while providing reliable through-thickness properties and consistent impact toughness. The **19-64 mm thickness range** represents the core application thickness for primary structural components in heavy machinery and critical construction equipment where robust performance is paramount. --- #### **1. International Standards** **Primary Standard:** **ASTM A514/A514M** - "Standard Specification for High-Yield-Strength, Quenched and Tempered Alloy Steel Plate, Suitable for Welding" **International Equivalents:** - **EN 10025-6**: S690QL - **JIS G3128**: SHY685 - **ISO 4950-3**: EQ 690 **Note:** While these international grades share similar strength classifications, ASTM A514 Grade M maintains specific chemical requirements that ensure consistent through-thickness performance in intermediate and heavy sections, particularly regarding hardenability and toughness preservation. --- #### **2. Chemical Composition** The chemical composition is optimized for through-thickness properties: | Element | Composition (Maximum %) | |---------|-------------------------| | Carbon (C) | 0.12-0.21 | | Manganese (Mn) | 0.70-1.00 | | Phosphorus (P) | 0.025 | | Sulfur (S) | 0.025 | | Silicon (Si) | 0.20-0.35 | | Chromium (Cr) | 0.40-0.65 | | Molybdenum (Mo) | 0.15-0.25 | | Vanadium (V) | 0.03-0.08 | | Boron (B) | 0.001-0.005 | | Titanium (Ti) | 0.01-0.03 | **Key Composition Features:** - **Carbon Optimization**: Balances strength requirements with weldability in thicker sections - **Titanium Microalloying**: Provides grain refinement for improved toughness - **Boron Treatment**: Ensures adequate hardenability through 64 mm thickness - **Tight Impurity Control**: Enhanced phosphorus and sulfur limits for improved Z-direction properties --- #### **3. Physical & Mechanical Properties** For plates in the 19-64 mm thickness range: | Property | Value | |----------|-------| | **Tensile Strength** | 760-895 MPa (110-130 ksi) | | **Yield Strength (min.)** | 690 MPa (100 ksi) | | **Elongation in 2" (min.)** | 16-18% | | **Reduction of Area (min.)** | 40% | | **Modulus of Elasticity** | 200 GPa (29,000 ksi) | | **Shear Modulus** | 77 GPa (11,200 ksi) | | **Poisson's Ratio** | 0.29 | | **Density** | 7.85 g/cm³ (0.284 lb/in³) | **Toughness Properties:** - **Charpy V-Notch Impact**: 40-54 J (30-40 ft-lbf) at -50°F (-45°C) - **Through-Thickness Properties**: Z-direction testing available per requirements - **Fracture Toughness**: Maintained through full thickness range --- #### **4. Product Applications** **Heavy Construction Machinery:** - Excavator main boom and arm sections - Crawler crane upper structures and boom components - Bulldozer push frames and blade support members **Mining Equipment:** - Haul truck body structural members and subframes - Shovel dipper arms and handle assemblies - Crusher main frames and jaw support structures **Material Handling Systems:** - Port crane main girders and boom sections - Stacker-reclaimer primary structural components - Heavy-duty forklift mast structural elements **Structural Applications:** - Bridge components for movable spans - Offshore platform structural modules - Power generation equipment support structures **Industrial Equipment:** - Large press frames and components - Heavy-duty trailer main beams - Specialized manufacturing equipment frames --- #### **5. Fabrication Characteristics** **Welding Guidelines:** - **Preheat Temperature**: 200-300°F (95-150°C) depending on thickness and restraint - **Interpass Temperature**: 400°F (205°C) maximum - **Recommended Processes**: SMAW, GMAW, FCAW - **Filler Metals**: E11018, E12018 class or equivalent - **Post-Weld Heat Treatment**: Stress relieving at 1100-1150°F (595-620°C) recommended for highly restrained joints **Forming & Machining:** - **Cold Forming**: Moderate capability with appropriate tooling - **Hot Forming**: Recommended for severe deformation (1150-1200°F / 620-650°C) - **Machinability**: 40-45% of B1112 steel - requires carbide tooling - **Cutting Methods**: Plasma, laser, and waterjet cutting recommended **Heat Treatment Status:** - Supplied in quenched and tempered condition - Maximum hardness: 302 HBW - Through-thickness hardness consistency maintained --- ### **Technical Summary** ASTM A514 Grade M in the 19-64 mm thickness range provides an excellent balance of high strength, reliable through-thickness properties, and consistent toughness for demanding structural applications. The titanium-enhanced grain refinement ensures maintained fracture toughness through the entire thickness range, making it particularly suitable for highly stressed components in construction, mining, and heavy equipment manufacturing. The material's robust performance characteristics, combined with its fabrication flexibility, make it a preferred choice for OEMs requiring dependable performance in severe service conditions. Proper attention to welding procedures, including adequate preheat and potential post-weld heat treatment, is essential to maintain the material's excellent mechanical properties in finished components. The grade's consistent performance through intermediate thicknesses makes it a versatile choice for a wide range of heavy engineering applications. -:- For detailed product information, please contact sales. -: ASTM A514 Steel, grade M, plate thickness 19-64 mm Specification Dimensions Size： Diameter 20-1000 mm Length <4288 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 A514 Steel, grade M, plate thickness 19-64 mm Properties -:- For detailed product information, please contact sales. -:
