Designed for the most demanding structural applications, it provides a minimum yield strength of **100 ksi (690 MPa)** in thicknesses up to and including 19 mm (0.75 inches). Grade B is the most commonly specified grade within the A514 family and is particularly valued in applications where maximizing load capacity while minimizing weight is critical, such in mobile equipment and heavy machinery. **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. * **Common Equivalent Standards:** * **EN / Europe:** The closest equivalent in terms of strength and treatment is EN 10025-6, Grade **S690QL** or **S690QL1**. However, chemical composition differs; direct substitution requires review. * **JIS / Japan:** Similar performance steels include JIS G3128, Grade SHY685. **Chemical Composition (Heat Analysis, % Maximum)** The chemistry of Grade B is optimized for deep hardenability and high strength after quenching and tempering. | Element | Content (%) | Element | Content (%) | | :--- | :--- | :--- | :--- | | Carbon (C) | 0.12 - 0.21 | Molybdenum (Mo) | 0.40 - 0.60 | | Manganese (Mn) | 0.70 - 1.00 | Boron (B) | 0.0005 - 0.005 | | Phosphorus (P) | 0.035 max | Copper (Cu)* | 0.15 - 0.50 | | Sulfur (S) | 0.040 max | Chromium (Cr) | 0.40 - 0.65 | | Silicon (Si) | 0.40 - 0.80 | Nickel (Ni)* | 0.25 - 0.50 | | Vanadium (V) | 0.01 - 0.10 | | | *\*Note: Copper and Nickel are specified to provide enhanced atmospheric corrosion resistance.* **Physical & Mechanical Properties (For Thickness ≤ 19 mm / 0.75 in)** * **Yield Strength (Minimum):** **100 ksi (690 MPa)** * **Tensile Strength:** **115 - 135 ksi (790 - 930 MPa)** * **Elongation in 2 in (50 mm) (Minimum):** **18%** * **Brinell Hardness:** Typically **235 - 293 HBW** * **Modulus of Elasticity:** ~29,000 ksi (200 GPa) * **Density:** 0.284 lb/in³ (7.85 g/cm³) * **Heat Treatment:** Supplied in the **Quenched and Tempered (Q&T)** condition. * **Charpy V-Notch Impact:** Typically meets minimum requirements of 20 ft-lb (27 J) at -50°F (-46°C) for Grade B, ensuring excellent low-temperature toughness. **Key Product Characteristics** 1. **Ultra-High Strength:** The 100 ksi yield strength enables significant weight reduction and performance enhancement in structural designs. 2. **Excellent Weldability:** Despite its high strength, it is formulated for good weldability using appropriate procedures. **Low-hydrogen welding practices are mandatory.** 3. **Superior Toughness:** The quenched and tempered microstructure, often with boron addition, provides excellent impact resistance and fracture toughness, even at low service temperatures. 4. **Atmospheric Corrosion Resistance:** The inclusion of Copper and Nickel offers approximately **twice the corrosion resistance** of standard carbon steel like ASTM A36. **Primary Applications** ASTM A514 Grade B is the workhorse for high-strength structural components across industries: * **Heavy Construction & Mining Equipment:** Boom arms, sticks, frames, buckets, and crawler tracks for excavators, cranes, draglines, and loaders. * **Material Handling:** Critical structural members for forklifts, container handlers, and heavy-duty lifting equipment. * **Truck & Trailer:** Chassis components, dump body liners, and fifth wheels for severe-service on/off-road vehicles. * **Agricultural Machinery:** High-stress frames and components in large combines and tractors. * **Energy & Infrastructure:** Towers, structural supports for heavy machinery, and components in wind turbine construction. * **Bridge Engineering:** For critical, weight-sensitive sections in movable bridges or where high fatigue resistance is needed. **Processing & Fabrication Notes** * **Welding (CRITICAL):** Requires strict low-hydrogen protocols (SMAW: E11018; SAW, FCAW, GMAW with appropriate filler). **Preheating (typically 200-400°F / 93-204°C)** is essential to prevent hydrogen-induced cracking (HIC). Post-weld heat treatment (PWHT) is often recommended for thick sections or highly restrained joints. * **Cutting:** Plasma, laser, and abrasive waterjet cutting are excellent. Oxy-fuel cutting is possible but may create a hardened heat-affected zone (HAZ) that requires grinding before welding. * **Machining:** Machinability rating is lower than mild steel. Requires rigid setups, positive rake carbide tooling, adequate power, and coolants. **Disclaimer:** This document is for informational purposes only. The final properties and suitability for a specific application depend on the manufacturer's processing.
