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. -: Malleable Iron Flange casting, Class 32510 Product Information -:- For detailed product information, please contact sales. -: Malleable Iron Flange casting, Class 32510 Synonyms -:- For detailed product information, please contact sales. -:

Malleable iron casting, Class 32510 Product Information -:- For detailed product information, please contact sales. -: ### **Product Introduction: Malleable Iron Casting, Class 32510 (ASTM A47)** **1. Overview** Class 32510 is a standard grade of **Ferritic Malleable Iron**, as defined by the ASTM International specification A47. Malleable iron begins as a white iron casting (hard and brittle) and undergoes an extensive heat treatment process called "malleablizing." This process converts the brittle iron carbide into irregularly shaped, temper carbon nodules (clusters) within a ferritic (iron) matrix. For Class 32510, this results in a material with an excellent combination of **high ductility, good machinability, moderate strength, and superior impact resistance at room temperature**. It is a classic and reliable material for a wide range of automotive, agricultural, and general industrial applications where toughness and the ability to withstand shock loading are critical. **2. Key International Standards** * **Primary Standard:** **ASTM A47 / A47M** - Standard Specification for Ferritic Malleable Iron Castings. This is the defining document for Class 32510, specifying its chemical, mechanical, and testing requirements. * **Related/Equivalent Standards:** * **SAE J158 / SAE AMS 5315C:** Society of Automotive Engineers specifications covering malleable iron castings. * **ISO 5922:** International standard for malleable cast irons. Class 32510 is broadly equivalent to grades such as **ISO 5922 JMB 35-10** or similar ferritic grades. * **DIN 1692:** German standard for malleable cast iron. * **GB/T 9440:** Chinese national standard. **3. Typical Chemical Composition** The composition is controlled to ensure the white iron solidification necessary for successful malleablizing. Typical ranges are: | Element | Typical Range (%) | Purpose/Effect | | :--- | :--- | :--- | | **Carbon (C)** | 2.20 - 2.70 | Provides the carbon for graphitization during annealing. Higher carbon improves machinability but can reduce strength. | | **Silicon (Si)** | 0.90 - 1.50 | The primary graphitizing agent; accelerates the annealing process. | | **Manganese (Mn)** | 0.15 - 0.50 | Counteracts sulfur; improves strength. | | **Sulfur (S)** | 0.02 - 0.12 max | Impurity; kept low to prevent brittleness. | | **Phosphorus (P)** | 0.02 - 0.12 max | Impurity; improves fluidity but reduces toughness if too high. | *Note: The "32510" designation itself does not prescribe strict chemical limits but is a performance-based grade. Chemistry is tailored by the foundry to consistently achieve the required mechanical properties for a given section size.* **4. Physical & Mechanical Properties (Per ASTM A47)** The key characteristic of Class 32510 is its high elongation, denoting excellent ductility. | Property | Minimum Requirement (ASTM A47) | Typical Value / Significance | | :--- | :--- | :--- | | **Tensile Strength** | **32500 psi** (224 MPa) | Indicates moderate load-bearing capacity. | | **Yield Strength (0.5% Ext under load)** | - | Typically ~205 MPa (30,000 psi). Good resistance to permanent deformation. | | **Elongation (in 2")** | **10%** | **The defining feature.** Exceptional ductility for a cast iron, allowing for significant plastic deformation before fracture. | | **Hardness** | Not specified, but typically | **110 - 156 HB** (Brinell). This relatively low hardness contributes to its **excellent machinability**. | | **Modulus of Elasticity** | - | ~25 x 10⁶ psi (172 GPa). | | **Impact Resistance** | Not specified in A47, but known for | **Excellent Charpy impact values at room temperature**, superior to most other cast irons and many cast steels. | | **Fatigue Strength** | - | Moderate; suitable for components with moderate cyclic loads. | | **Damping Capacity** | - | Good; better than steel, providing some vibration absorption. | **5. Product Applications** Class 32510 is favored for components that require a blend of castability, strength, and most importantly, **toughness and shock resistance**. * **Automotive & Transportation:** * **Wheel Hubs and Spindles:** For trailers and some passenger vehicles. * **Brake Components:** Brake calipers, brackets, and clutch pedals. * **Steering Components:** Steering knuckles, tie rod ends, and gear housings. * **Driveline Parts:** Differential carriers, universal joint yokes, and axle components. * **Agricultural & Off-Highway Equipment:** * **Tractor Components:** Linkages, lever arms, hitch parts, and transmission cases. * **Implement Parts:** Mower deck components, plow shares, and gear housings. * **General Industrial & Hardware:** * **Pipe Fittings & Valves:** Especially for gas and water lines where pressure tightness and toughness are needed. * **Hand Tools:** Wrench sockets, pipe wrenches, and vise parts. * **Mining & Construction Hardware:** Chain links, hooks, and coupling components. * **Electrical Fittings:** Conduit bodies and junction boxes. **6. Advantages and Limitations** **Advantages:** * **Exceptional Ductility & Toughness:** Best impact resistance among common cast irons. * **Excellent Machinability:** Due to its ferritic matrix and low hardness. * **Good Pressure Tightness:** Reliable for fluid and gas handling applications. * **Good Castability:** Can produce complex, thin-walled shapes. * **Cost-Effective:** Often more economical than ductile iron or steel castings for high-volume, small-to-medium parts requiring toughness. **Limitations:** * **Lower Strength:** Compared to higher-grade malleable irons (e.g., Pearlitic grades like 45006) or ductile iron (e.g., 65-45-12). * **Lengthy Heat Treatment:** The malleablizing process (often 50+ hours) adds time and cost compared to as-cast materials. * **Section Size Sensitivity:** Properties can vary significantly with casting wall thickness. * **Not for High-Temperature Service:** The temper carbon structure is unstable above ~800°F (425°C). **Conclusion** ASTM A47 Class 32510 Ferritic Malleable Iron remains a vital engineering material where **reliable toughness and ease of manufacturing** are paramount. Its unique combination of castability, machinability, and shock absorption ensures its continued use in critical, safety-related components across diverse industries, from the automotive sector to heavy-duty hardware. -:- For detailed product information, please contact sales. -: Malleable iron casting, Class 32510 Specification Dimensions Size： Diameter 20-1000 mm Length <6573 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. -: Malleable iron casting, Class 32510 Properties -:- For detailed product information, please contact sales. -:
