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. -: Ductile Iron Flange grade 80-60-03 Product Information -:- For detailed product information, please contact sales. -: Ductile Iron Flange grade 80-60-03 Synonyms -:- For detailed product information, please contact sales. -:

Ductile Iron grade 80-60-03 Product Information -:- For detailed product information, please contact sales. -: ### **Product Technical Data Sheet: Ductile Iron (Nodular Iron) Grade 80-60-03** #### **1. Product Overview** Ductile Iron (DI) Grade 80-60-03 is a high-strength, pearlitic-ferritic grade engineered for applications demanding superior tensile and yield strength alongside good wear resistance, while maintaining a fundamental level of ductility. The grade designation indicates minimum mechanical properties: **80 ksi (550 MPa) tensile strength, 60 ksi (415 MPa) yield strength, and 3% elongation**. This grade is typically produced in the **as-cast** or **normalized** condition, resulting in a matrix structure of predominantly pearlite with islands of ferrite surrounding the graphite nodules. It serves as a critical material solution where the higher strength of steel is needed but the castability, damping, and cost-effectiveness of iron are essential. #### **2. Governing International Standards** This grade is recognized under all major international ductile iron specifications. * **Primary Designation: ASTM A536** - *Standard Specification for Ductile Iron Castings*. The grade is designated as **80-60-03**. * **Alternative Designations:** * **ISO 1083:** Designated as **EN-GJS-600-3** or **JS/1050-03** (600 MPa tensile, 370 MPa yield, 3% elongation). Slight variations exist, but 80-60-03 is the direct commercial equivalent. * **EN 1563:** (European Standard) **EN-GJS-600-3**. * **SAE J434:** (Automotive) **D5506**. * **Key Testing Standards:** * **Tensile Test:** ASTM E8 / ISO 6892-1. * **Microstructure:** ASTM A247 / ISO 945 (Nodularity typically >80%, Type I & II graphite in a pearlitic matrix). #### **3. Typical Chemical Composition (As-Cast / Normalized)** The chemistry is balanced to promote a pearlitic matrix in the cast section without full annealing. | Element | Target Range (%) | Functional Role | | :--- | :--- | :--- | | **Carbon (C)** | 3.5 - 3.8 | Ensures castability and graphite formation. Slightly lower than ferritic grades to strengthen the matrix. | | **Silicon (Si)** | 2.0 - 2.5 | Moderate level. Lower than ferritic grades to allow pearlite formation; higher levels promote ferrite. | | **Manganese (Mn)** | 0.2 - 0.5 | A key pearlite stabilizer. Higher Mn content helps achieve the required pearlitic structure, especially in heavier sections. | | **Magnesium (Mg)** | 0.03 - 0.05 | Essential nodulizing element. | | **Copper (Cu)** | 0.4 - 0.8 | **Primary alloying element for this grade.** A strong and uniform pearlite promoter, essential for achieving consistent high strength throughout the casting. | | **Tin (Sn)** | 0 - 0.1 | Potent pearlite stabilizer; used in small amounts for section uniformity. | | **Molybdenum (Mo)** | 0 - 0.3 | May be added in heavy sections to prevent ferrite formation and increase hardenability. | | **Phosphorus (P)** | ≤ 0.04 | Kept very low. | | **Sulfur (S)** | ≤ 0.015 | Kept very low. | #### **4. Physical & Mechanical Properties** This grade is defined by high strength and stiffness, with moderate ductility. | Property | Minimum / Typical Value | Test Standard & Notes | | :--- | :--- | :--- | | **Tensile Strength, min.** | **80 ksi (550 MPa)** | ASTM A536 / ISO 1083 | | **Yield Strength (0.2% offset), min.** | **60 ksi (415 MPa)** | High yield strength is a key feature (~0.75 of UTS). | | **Elongation, min.** | **3%** (in 2 inches or 50mm) | Lower ductility than ferritic grades but sufficient for many high-strength applications. | | **Hardness (Brinell)** | 201 - 269 HBW | Typically 217-241 HBW. Good wear resistance due to hard pearlite. | | **Modulus of Elasticity** | 24 - 25 x 10⁶ psi (165 - 172 GPa) | High stiffness, comparable to steel. | | **Charpy Impact (Unnotched) @ 23°C** | 25 - 40 J (Typical) | Impact resistance is lower than ferritic grades but adequate for many static/dynamic loads. | | **Fatigue Endurance Limit** | ~250 - 275 MPa (≈ 0.45-0.5 x UTS) | Good fatigue performance under cyclic loading. | | **Density** | 0.256 lb/in³ (7.1 g/cm³) | | | **Microstructure** | **70-95% Pearlite** matrix with **>80% Nodularity** (Type I & II graphite). Balance is ferrite surrounding the nodules. | The pearlitic matrix provides the high strength and wear resistance. | #### **5. Product Applications** Grade 80-60-03 is the workhorse high-strength ductile iron, specified for components under high static and dynamic stress. * **Automotive & Trucking (Primary Market):** **Crankshafts, camshafts, differential cases, ring gears, hub carriers, steering knuckles, disc brake calipers.** Its strength withstands high torque and bending loads. * **Heavy Machinery & Construction:** **Gearbox housings, hydraulic cylinder barrels, pump bodies, rollers, idlers, and heavy-duty axle components** for mining and agricultural equipment. * **Industrial Machinery:** **Press frames, spindles, machine tool components, compressor crankshafts, and valve bodies** requiring high stiffness and fatigue resistance. * **Railway:** **Bogie frames, coupler components, and brake discs.** * **Power Transmission:** **Large gear blanks** where its castability for complex shapes and good machinability are advantageous over steel forgings. #### **6. Fabrication & Heat Treatment Notes** * **Primary Condition:** **As-Cast or Normalized.** Normalizing (heating to 870-900°C, air cooling) refines the pearlite structure, ensuring consistent high strength and improved mechanical properties throughout the casting. * **Machinability:** **Fair to Good.** More demanding than ferritic grades (60-40-18) due to the harder pearlitic matrix, but still superior to most steels. Requires robust tooling and correct parameters. * **Weldability:** **Poor.** Not recommended for general fabrication welding. If repair is unavoidable, it requires stringent procedures: high pre-heat (500-600°C), specialized nickel-iron electrodes, and controlled post-weld cooling to avoid hard, crack-susceptible zones. Stress relief is mandatory. #### **7. Ordering Information** Specify: **"Ductile Iron Castings, ASTM A536 Grade 80-60-03 (Normalized/As-Cast)"**. Key details to include: * **Condition:** Specify if normalized heat treatment is required. * **Drawing/Part Specification.** * **Required certifications:** Foundry test report with mechanical properties (tensile, yield, elongation, hardness). Microstructure specification (e.g., minimum pearlite content) may be required. * **Any special requirements:** Non-destructive testing (NDT) such as ultrasonic or magnetic particle inspection for critical areas.
