Product Overview** ASTM A514 Grade E is a premium high-strength, quenched and tempered alloy steel plate designed for the most demanding structural applications requiring exceptional combinations of strength, toughness, and atmospheric corrosion resistance. With a **minimum yield strength of 100 ksi (690 MPa)** in thicknesses up to 19 mm, Grade E is distinguished by its specific alloying system containing **Chromium and Copper**, which provides superior resistance to atmospheric corrosion—approximately **four times that of carbon steel**. This grade is the optimal choice for critical exposed structures where longevity and durability under environmental exposure are paramount. ### **2. International Standards Compliance** - **Primary Standard:** ASTM A514/A514M - *Standard Specification for High-Yield-Strength, Quenched and Tempered Alloy Steel Plate, Suitable for Welding* - **Dimensional Standard:** ASTM A6/A6M - *General Requirements for Rolled Structural Steel Bars, Plates, Shapes, and Sheet Piling* - **Key International Equivalents:** - **EN Standard:** EN 10025-6 Grade **S690QL** (Note: This is a strength and treatment equivalent; the enhanced corrosion resistance of A514 Grade E is a unique feature not fully replicated in standard EN grades.) - **Weathering Steel Equivalents:** While not direct chemical equivalents, performance-wise it aligns with the intent of **ASTM A242 / A588** weathering steels but at much higher strength levels. - **JIS Standard:** JIS G3128 **SWH 685A** (High-Strength Weathering Steel for Welded Structures) shares similar corrosion resistance philosophy. ### **3. Chemical Composition (Heat Analysis, % by Weight)** | Element | Min (%) | Max (%) | Metallurgical Function & Rationale | |---------|---------|---------|-----------------------------------| | Carbon (C) | 0.12 | 0.20 | Base strength and hardenability. Controlled upper limit ensures weldability. | | Manganese (Mn) | 0.40 | 0.70 | Austenite stabilizer and solid solution strengthener. Lower range than other A514 grades. | | Phosphorus (P) | — | 0.035 | Impurity control for weldability and toughness. | | Sulfur (S) | — | 0.040 | Impurity control. | | Silicon (Si) | 0.15 | 0.35 | Deoxidizer. Lower range aids in surface quality for weathering. | | **Chromium (Cr)** | **0.40** | **0.65** | **Key element for atmospheric corrosion resistance and hardenability.** | | **Copper (Cu)** | **0.20** | **0.40** | **Primary element for enhanced atmospheric corrosion resistance.** Forms protective patina. | | Nickel (Ni) | 0.25 | 0.50 | Improves toughness and supports corrosion resistance. | | Molybdenum (Mo) | 0.15 | 0.25 | Enhances hardenability, strength, and tempering resistance. | | Vanadium (V) | 0.01 | 0.10 | Grain refiner and precipitation strengthener. | | Boron (B) | 0.0005 | 0.005 | Powerful hardenability enhancer, ensuring properties in thin sections. | **Distinguishing Feature:** The combination of **Cu + Cr + Ni** is central to Grade E's identity, providing its signature weathering capability without sacrificing high strength. ### **4. Mechanical & Physical Properties (Thickness ≤ 19 mm)** | Property | Specification Requirement | Typical Value | Test Method | |----------|--------------------------|---------------|-------------| | **Yield Strength (min)** | **100 ksi (690 MPa)** | 105 – 115 ksi (725 – 795 MPa) | ASTM A370 | | **Tensile Strength** | **115 – 135 ksi (790 – 930 MPa)** | 120 – 128 ksi (825 – 880 MPa) | ASTM A370 | | **Elongation in 2 in.

Heat Treatment & Microstructure** - **Condition as Supplied:** Quenched and Tempered (Q&T). - **Microstructure:** Fine-grained tempered martensite/bainite, providing the optimal blend of strength and toughness. - **Key Benefit:** The heat treatment ensures homogeneous properties throughout the plate thickness (≤19 mm), maximizing the performance of the corrosion-resistant alloying system. ### **6. Key Product Characteristics** 1. **Superior Atmospheric Corrosion Resistance:** The primary defining feature. The Cu-Cr-Ni system promotes the formation of a dense, adherent rust layer (patina) that dramatically slows further corrosion, ideal for unpainted, exposed structures. 2. **Ultra-High Strength:** Maintains the 100 ksi minimum yield strength, enabling lighter, more efficient designs. 3. **Excellent Weldability:** Designed to be welded using established low-hydrogen procedures common to high-strength steels. 4. **Good Toughness:** Provides reliable impact resistance for dynamic loading conditions and low-temperature service. ### **7. Primary Applications** Grade E is specified where high strength and long-term durability in exposed conditions converge: * **Bridges & Infrastructure:** Critical, exposed members in bridges (particularly long-span or coastal), sign structures, and high-mast light poles where painting maintenance is difficult. * **Construction & Mining Equipment:** Exposed booms, arms, and frames on cranes, excavators, and draglines operating in corrosive environments (coastal, chemical, or high-humidity areas). * **Power Transmission & Renewable Energy:** Lattice towers, utility structures, and components for wind turbine nacelles and towers. * **Transportation:** Structural components for specialized railcars, heavy haul trailers, and shipping containers exposed to weather. * **Architectural & Sculptural:** For high-strength sculptural elements or architectural features intended to develop a stable, protective weathering finish. ### **8. Fabrication Guidelines** * **Welding:** * **Essential:** Use low-hydrogen welding processes (SMAW, GMAW, FCAW, SAW). * **Electrodes/Fillers:** AWS E11018, ER110S-G, or equivalent classifications rated for weathering steels. * **Preheat/Interpass:** Preheat of 200°F (93°C) minimum is recommended. Maintain interpass temperature below 400°F (204°C). * **Cutting:** Plasma, laser, or waterjet cutting are preferred. Oxy-fuel cutting is acceptable but may affect the corrosion performance at the cut edge; light grinding is recommended. * **Machining:** Requires more power than mild steel. Use positive rake carbide tooling with adequate coolant. * **Corrosion Performance Note:** The protective patina forms over time (1-3 years) and requires wet/dry cycles. Performance is reduced in constantly wet, submerged, or high-chloride (salt spray) environments without additional protection. ### **9. Quality Assurance** * Supplied with Certified Mill Test Reports (CMTRs) including chemistry, mechanical properties, and Charpy impact results. * Heat number traceability is standard. * Ultrasonic testing available as a supplementary requirement (ASTM A578). ### **10. Important Distinctions from Other Grades** Unlike Grades A, B, C, and D, which have varying secondary alloy focuses, **Grade E is uniquely alloyed and specified for its weathering corrosion resistance at high strength levels.** It should not be considered a direct substitute for other A514 grades unless this specific environmental performance is required. ### **11. Disclaimer** This technical data sheet is for informational purposes. Specifications are subject to change. For design and procurement, always consult the latest official **ASTM A514/A514M** specification and certified material test reports. Welding procedures must be qualified to applicable codes (e.g., AWS D1.1, D1.5).
