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. -: AISI 1132 Steel Flange, cold drawn, 19-32 mm (0.75-1.25 in) round Product Information -:- For detailed product information, please contact sales. -: AISI 1132 Steel Flange, cold drawn, 19-32 mm (0.75-1.25 in) round Synonyms -:- For detailed product information, please contact sales. -:

Product Overview** **AISI 1132** is a medium-carbon, **manganese-sulfur alloyed steel** designed to offer a balanced combination of good machinability, moderate strength, and reasonable hardenability. When supplied in the **cold drawn** condition, the material undergoes a precision finishing process that enhances its mechanical properties, dimensional accuracy, and surface quality. This datasheet details the specifications for **cold drawn round bar** in the **19 mm to 32 mm (0.75 in to 1.25 in)** diameter range. This product is engineered as a versatile, general-purpose steel for components that require **better machinability than standard medium-carbon grades (e.g., 1045) and higher strength than low-carbon free-machining grades (e.g., 1117)**, often serving as a "bridge" material between these two categories. It is suitable for parts that may be used in the as-drawn state or heat-treated to achieve higher strength levels. **Key Advantages of Cold Drawn AISI 1132:** * **Enhanced Machinability:** The sulfur addition (typically 0.08-0.13%) provides free-machining characteristics, improving chip formation, reducing cutting forces, and extending tool life compared to non-sulfurized grades of similar carbon content. * **Good Strength-to-Machinability Ratio:** Offers a favorable balance, providing appreciable strength in the cold drawn condition while retaining significantly better machinability than plain carbon steels like 1035 or 1045. * **Improved Dimensional Accuracy & Finish:** The cold drawing process delivers tight tolerances, excellent straightness, and a bright, smooth surface ready for precision machining or direct use. * **Heat Treatable:** With its medium carbon content (0.27-0.34%), it is capable of responding to quenching and tempering to achieve higher strength and hardness levels for more demanding applications. --- ### **2. Chemical Composition (Standard % by Weight)** The composition is designed for a balance of strength, machinability, and moderate hardenability. | Element | Content (%) | Function & Implication | | :--- | :--- | :--- | | **Carbon (C)** | 0.27 - 0.34 | **Primary strength element.** Provides the basis for response to heat treatment (quenching & tempering). Higher than 1117 series for increased strength. | | **Manganese (Mn)** | 1.35 - 1.65 | **Key for hardenability and machinability.** Increases hardenability to allow through-hardening of moderate sections. Combines with sulfur to form beneficial MnS inclusions. | | **Phosphorus (P)** | ≤ 0.040 | Residual element, controlled for toughness. | | **Sulfur (S)** | 0.08 - 0.13 | **Machinability enhancer.** Forms manganese sulfide (MnS) inclusions that act as chip breakers, improving machinability but slightly reducing transverse ductility and weldability. | | **Iron (Fe)** | Balance | Base metal. | --- ### **3. Typical Physical & Mechanical Properties (Cold Drawn Condition)** *Properties are indicative for this diameter range and can vary with the degree of cold work.* | Property | Typical Value (Metric) | Typical Value (Imperial) | | :--- | :--- | :--- | | **Tensile Strength** | 550 - 690 MPa | 80,000 - 100,000 psi | | **Yield Strength (0.2% Offset)** | 480 - 620 MPa | 70,000 - 90,000 psi | | **Elongation (in 50 mm)** | 12% - 20% | 12% - 20% | | **Reduction of Area** | 35% - 50% | 35% - 50% | | **Hardness** | 179 - 229 HB | 179 - 229 HB | | **Machinability Rating** | ~ **85%** (AISI 1212 = 100%) | Good; superior to 1035/1045, but less than 1117/12L14. | | **Surface Condition** | **Bright, Smooth** | Free of mill scale. | --- ### **4.

Primary Applications** Cold drawn AISI 1132 is selected for components that benefit from its combination of good machinability, ready strength, and heat treatability. * **General Machinery Parts:** Shafts, spindles, studs, bolts, and pins that require more strength than low-carbon steels and are often machined in volume. * **Automotive Components:** Clutch parts, gear shafts, steering components, and other non-critical stressed parts that are machined and may be heat-treated. * **Fasteners & Tools:** Higher-strength bolts, set screws, and tool holders (for non-cutting applications). * **Agricultural Equipment:** Pivot pins, linkage components, and other wear parts that can be surface hardened. * **Precision Machined Parts:** Bushings, fittings, and sleeves produced on CNC lathes and screw machines where the bright finish and consistent machining characteristics are valued. --- ### **6. Processing Notes** * **Heat Treatment:** Well-suited for **quenching and tempering**. Typical process: Austenitize at 830-860°C (1525-1580°F), quench in oil, and temper to desired hardness/strength (often to a final hardness of 25-40 HRC). Can also be **induction or flame hardened** for wear surfaces. Stress relieving before hardening complex parts is recommended. * **Machinability:** **Good.** The sulfur addition provides noticeable chip-breaking improvement over non-resulfurized grades. Use sharp tools with positive rake angles. Cutting forces are higher than for 1117 series. * **Weldability:** **Fair to Poor.** The combined effect of medium carbon and sulfur increases the risk of hardening and cracking in the heat-affected zone (HAZ). Pre-heat and post-heat treatments are usually necessary for successful welding; it is not recommended for primary welded structures. * **Cold Forming:** Moderate. The cold drawn condition is already work-hardened. Further bending or forming may require annealing for severe operations. * **Surface Preparation:** The bright drawn surface is suitable for direct plating or painting with minimal preparation. --- **Disclaimer:** The information provided is for reference purposes.
