A flange—also referred to as a flange plate or rim—is a component used to connect shafts to one another, or, more commonly, to join the ends of pipes. Flanges are also utilized at the inlet and outlet ports of equipment to facilitate connections between two devices—for instance, the flange on a speed reducer. A "flange connection" or "flanged joint" refers to a detachable joint assembly comprising three interconnected elements—a flange, a gasket, and bolts—that together form a sealed structural unit. In the context of piping systems, a "pipe flange" specifically denotes a flange used for plumbing within the installation; when applied to equipment, it refers to the inlet or outlet flange of that specific device. Flanges feature a series of holes through which bolts are inserted to securely fasten the two flanges together, while a gasket placed between the flanges ensures a leak-proof seal. Flanges are broadly categorized into three types: threaded (screw-in) flanges, welded flanges, and clamp-type flanges. Flanges are invariably used in pairs; threaded flanges are suitable for low-pressure piping applications, whereas welded flanges are required for systems operating at pressures exceeding 4 kilograms per square centimeter. A sealing gasket is inserted between the two flange plates, which are then firmly secured using bolts. The thickness of a flange—as well as the specifications of the bolts used to fasten it—vary depending on the specific pressure rating required for the application. When connecting equipment such as water pumps or valves to piping systems, the corresponding connection points on these devices are often manufactured in the shape of a matching flange; this method of attachment is also referred to as a "flange connection." Generally, any connecting component that utilizes bolts to join and seal the perimeters of two flat surfaces—such as the joints in ventilation ducts—is termed a "flange"; such components may collectively be classified as "flange-type parts." However, since such a connection often constitutes merely a *portion* of a larger device—for instance, the interface between a flange and a water pump—it would be inappropriate to classify the entire water pump itself as a "flange-type part." Conversely, smaller components—such as valves—that feature such flanged interfaces may indeed be appropriately categorized as "flange-type parts." -:- For detailed product information, please contact sales. -: ASTM A710 Steel Flange, grade B, 13 - 19 mm thicknesses Product Information -:- For detailed product information, please contact sales. -: ASTM A710 Steel Flange, grade B, 13 - 19 mm thicknesses Synonyms -:- For detailed product information, please contact sales. -:

ASTM A710 Steel, grade B, 13 - 19 mm thicknesses Product Information -:- For detailed product information, please contact sales. -: ### **Product Datasheet: ASTM A710 Grade B High-Strength Low-Alloy Steel Plate** #### **Product Overview** ASTM A710 Grade B is a high-strength, low-carbon copper-precipitation-strengthened, low-alloy steel. Its unique "age-hardening" heat treatment allows it to achieve very high strength and excellent toughness without requiring a conventional quench and temper process. This makes it exceptionally well-suited for applications where welding is critical, as it minimizes the risk of heat-affected zone (HAZ) cracking. Plates in the 13 mm to 19 mm thickness range deliver an optimal balance of high strength and fabrication ease. **Key Advantages:** * **High Strength & Toughness:** Offers a minimum yield strength of 585 MPa (85 ksi) with exceptional impact toughness at low temperatures. * **Superior Weldability:** The low carbon content (Carbon Max 0.07%) significantly reduces preheat requirements and eliminates post-weld heat treatment in most cases, even at this strength level. * **Age-Hardening:** Gains its strength from a solution treatment and aging process, resulting in a more uniform microstructure. * **Excellent Corrosion Resistance:** The specified copper content provides enhanced resistance to atmospheric corrosion. --- #### **International Standard** The manufacturing and testing of this product are strictly in accordance with the latest version of: * **ASTM A710 / A710M:** Standard Specification for Age-Hardening Low-Carbon Nickel-Copper-Chromium-Molybdenum-Columbium Alloy Structural Steel Plates. --- #### **Chemical Composition (Heat Analysis, %)** The following table details the required chemical composition for ASTM A710 Grade B. | Element | Content (%) | Element | Content (%) | | :--- | :--- | :--- | :--- | | Carbon (C), max | 0.07 | Nickel (Ni) | 0.70 - 1.00 | | Manganese (Mn) | 0.40 - 0.80 | Chromium (Cr) | 0.40 - 0.80 | | Phosphorus (P), max | 0.025 | Molybdenum (Mo)| 0.15 - 0.25 | | Sulfur (S), max | 0.025 | Columbium (Cb) [Niobium] | 0.02 - 0.08 | | Silicon (Si), max | 0.40 | Copper (Cu) | 1.00 - 1.30 | | *Note: Columbium (Cb) is also known as Niobium (Nb).* | | | | --- #### **Mechanical Properties (For Thickness 13 - 19 mm)** Mechanical properties are guaranteed in the transverse direction. | Property | Value | Unit | | :--- | :--- | :--- | | **Tensile Strength, min** | 620 | MPa (90 ksi) | | **Yield Strength (0.2% Offset), min** | 585 | MPa (85 ksi) | | **Elongation in 2 in (50 mm), min** | 20 | % | | **Reduction of Area, min** | 50 | % | **Impact Properties (Charpy V-Notch):** * **Test Temperature:** -85°F (-65°C) * **Minimum Average Impact Energy:** 34 J (25 ft·lb) --- #### **Physical Properties (Typical Values)** * **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 x 10⁻⁶/°C (20-100°C) --- #### **Heat Treatment Condition** This product is supplied in **Class 3 (Aged)** condition, which involves: 1. **Solution Treatment:** Heated to a high temperature to put alloying elements into solid solution, followed by rapid cooling. 2. **Aging:** Heated to a moderate temperature for a specific time to precipitate fine alloy particles (e.g., copper), which strengthens the steel. This process is fundamental to achieving the steel's unique combination of properties. --- #### **Product Applications** ASTM A710 Grade B is ideal for critical, high-performance applications where weldability, toughness, and weight savings are paramount. * **Pressure Vessels & Reactors:** For high-pressure gas storage, chemical processing, and power generation. * **Offshore & Marine Structures:** Platform components, ship hulls, and superstructures requiring high strength and corrosion resistance. * **Cryogenic Applications:** Containment systems for liquefied gases (LNG, nitrogen) due to its exceptional low-temperature toughness. * **Construction Equipment:** Booms, arms, and frames for cranes and excavators where fatigue resistance is critical. * **Military & Aerospace:** Structural components that benefit from its high strength-to-weight ratio. --- #### **Fabrication & Welding Notes** * **Welding:** This is a key advantage of A710 Grade B. Due to its very low carbon equivalent, it can often be welded without preheat. However, standard low-hydrogen welding practices (e.g., SMAW, GMAW, FCAW with low-H₂ electrodes) are mandatory. For highly restrained joints or very low ambient temperatures, a minimal preheat of 50-100°F (10-38°C) may be recommended. * **Post-Weld Heat Treatment (PWHT):** Generally not required. The aging temperature is low enough that it does not adversely affect the base metal properties after welding. * **Cutting & Forming:** Can be cut by plasma arc, laser, or waterjet. It has good formability due to its low yield-to-tensile ratio. --- **Disclaimer:** This datasheet is for informational purposes only.
