When supplied in thicknesses of 19 mm (0.75 inches) and under, it achieves its maximum specified yield strength of **100 ksi (690 MPa)**. This makes it a premier choice for critical structural components in demanding environments where weight savings and structural integrity are paramount. **Key International Standards** * **Primary Specification:** ASTM A514 / A514M - Standard Specification for High-Yield-Strength, Quenched and Tempered Alloy Steel Plate, Suitable for Welding. * **Dimensional Standards:** Typically supplied in accordance with ASTM A6/A6M for general requirements. * **Common Equivalent Standards:** * **EN / Europe:** EN 10025-6, Grade S690Q (Note: Not a direct equivalent but similar in strength and treatment). * **Others:** Often requested to meet specific customer or project specifications. **Chemical Composition (Heat Analysis, % Maximum)** The precise alloying elements are balanced to achieve high strength and hardenability through heat treatment. | Element | Content (%) | Element | Content (%) | | :--- | :--- | :--- | :--- | | Carbon (C) | 0.15 - 0.21 | Vanadium (V) | 0.03 - 0.08 | | Manganese (Mn) | 0.95 - 1.30 | Titanium (Ti) | 0.01 - 0.03 | | Phosphorus (P) | 0.035 max | Zirconium (Zr) | 0.05 - 0.15 | | Sulfur (S) | 0.040 max | Boron (B) | 0.001 - 0.005 | | Silicon (Si) | 0.40 - 0.80 | Copper (Cu)* | 0.20 - 0.40 | | Chromium (Cr) | 0.50 - 0.80 | Molybdenum (Mo) | 0.18 - 0.28 | | Nickel (Ni)* | 0.25 - 0.50 | | | *\*Note: Copper and Nickel are specified for enhanced atmospheric corrosion resistance.* **Physical & Mechanical Properties (For Thickness ≤ 19 mm / 0.75 in)** * **Yield Strength (Minimum):** 100 ksi (690 MPa) * **Tensile Strength:** 110 - 130 ksi (760 - 895 MPa) * **Elongation in 2 in (50 mm) (Minimum):** 18% * **Reduction of Area (Minimum):** 40% * **Brinell Hardness:** Typically 235 - 293 HBW * **Modulus of Elasticity:** ~29,000 ksi (200 GPa) * **Density:** 0.284 lb/in³ (7.85 g/cm³) * **Poisson's Ratio:** 0.29 * **Heat Treatment:** Supplied in the Quenched and Tempered (Q&T) condition to achieve the specified mechanical properties. **Key Product Characteristics** 1. **Extremely High Strength:** The 100 ksi minimum yield strength allows for lighter, more efficient designs compared to conventional structural steels. 2. **Good Weldability:** Despite its high strength, A514 Grade A is designed to be welded using standard procedures (preheat and low-hydrogen practices are essential). 3. **Toughness:** Offers good impact resistance at service temperatures, making it suitable for dynamic loading conditions. 4. **Atmospheric Corrosion Resistance:** The specified Copper and Nickel content provides marginally better corrosion resistance than carbon steels, approximately twice that of ASTM A36 steel. **Primary Applications** Due to its premium properties, ASTM A514 Grade A (t≤19mm) is extensively used in: * **Construction Machinery:** Boom arms, chassis, turntables, and critical linkages for cranes, excavators, and mining equipment. * **Material Handling:** High-stress components of forklifts, heavy-duty lifting frames, and conveyor systems. * **Transportation:** Frame rails, suspension components, and dump body liners for severe-duty trucks and trailers. * **Bridge Construction:** For critical, weight-sensitive members in movable bridges or long-span bridges. * **Industrial Equipment:** Supports and frames for heavy presses, injection molding machines, and other high-load machinery. * **Military & Defense:** Structural components in vehicles and equipment where ballistic protection or high mobility is required. **Processing & Fabrication Notes** * **Welding:** Requires strict adherence to low-hydrogen welding practices (e.g., SMAW with E11018 electrodes). Preheating (typically 200-300°F / 93-149°C) and post-weld heat treatment (PWHT) are often recommended, especially for thicker sections or restrained joints. * **Cutting:** Can be effectively cut by plasma, laser, or waterjet. Oxy-fuel cutting requires care to avoid hardening of the cut edge. * **Machining:** Machinability is fair; it requires more power and slower speeds than mild steel. Use of positive rake angles and carbide tooling is recommended. **Disclaimer:** This information is for reference purposes. For procurement, design, or fabrication, always consult the latest official ASTM A514/A514M specification and involve qualified metallurgical or engineering expertise. Properties and recommendations may vary by manufacturer and specific heat treatment. -:- For detailed product information, please contact sales. -: ASTM A514 Steel, grade A, plate thickness ≤ 19 mm Specification Dimensions Size： Diameter 20-1000 mm Length <5907 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 A, plate thickness ≤ 19 mm Properties -:- For detailed product information, please contact sales. -:
