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 1536 High Manganese Carbon Steel Flange, Cold Drawn Bar Product Information -:- For detailed product information, please contact sales. -: AISI 1536 High Manganese Carbon Steel Flange, Cold Drawn Bar Synonyms -:- For detailed product information, please contact sales. -:

AISI 1536 High Manganese Carbon Steel, Cold Drawn Bar Product Information -:- For detailed product information, please contact sales. -: ### **Product Introduction: AISI 1536 High Manganese Carbon Steel, Cold Drawn Bar** **Overview** AISI 1536 is a high-manganese, medium-carbon alloy steel supplied in the precision **cold drawn bar** condition. This manufacturing process involves drawing hot-rolled stock through a die at room temperature, which significantly enhances dimensional accuracy, surface finish, and mechanical properties through strain hardening. The steel's defining characteristic is its elevated manganese content (1.20-1.50%), which provides excellent inherent hardenability. Combined with the benefits of cold drawing, AISI 1536 becomes a premium, ready-to-machine material offering increased strength, exceptional straightness, and tight tolerances. It is engineered for high-performance components requiring precision machining and is often the substrate for subsequent heat treatment to achieve maximum properties. **Key Features & Advantages** * **Enhanced Mechanical Properties:** The cold drawing process substantially increases yield and tensile strength via strain hardening, providing a stronger "as-supplied" material than hot-rolled stock. This can serve as a final strength condition for some applications or an ideal pre-hardened state for machining. * **Superior Dimensional Control & Surface Finish:** Delivers tight diameter tolerances (per ASTM A108), excellent straightness, and a smooth, bright, scale-free surface. This reduces machining allowances, improves part assembly and function, and often eliminates secondary finishing. * **Excellent Hardenability & Heat Treatment Response:** The high manganese content ensures deep and uniform hardenability. When final heat treatment (quenching & tempering) is required, the consistent cold drawn microstructure provides a predictable starting point for uniform final properties. * **Good Machinability for its Strength Class:** Offers fair and consistent machinability for an alloy steel of its strength level, enabling reliable and efficient production of precision components with extended tool life predictability. * **Manufacturing Efficiency:** Acts as a near-net-shape material that reduces rough machining time, minimizes material waste, and streamlines the production flow for high-strength, precision parts. --- ### **1.

Product Applications** AISI 1536 cold drawn bars are specified for critical, high-strength components where precision and reliability are paramount. * **High-Strength Precision Shafting:** Axle shafts, drive shafts, spindle shafts, and hydraulic piston rods requiring straightness, a fine surface finish, and high yield strength. * **High-Performance Fasteners:** Bolts, studs, and pins machined from bar stock, often heat-treated to very high strength levels (comparable to or exceeding Grade 8.8/10.9). * **Hydraulic & Pneumatic Components:** Cylinder rods, actuator shafts, and valve spools for high-pressure systems. * **Automotive Drivetrain Components:** Transmission shafts, steering linkage parts, and crankshafts. * **Gear and Bearing Components:** Blanks for through-hardened gears, pinions, and rollers. * **Tooling and Machine Parts:** Heavy-duty ejector pins, guide rods, dowel pins, and fixture components. --- ### **4. Important Considerations** * **Residual Stress Management:** Cold drawing induces significant residual surface stresses. For parts undergoing asymmetric or heavy machining, **a stress-relieving heat treatment (e.g., at 550-650°C / 1020-1200°F) prior to final machining is strongly recommended** to prevent distortion. * **Heat Treatment Strategy:** Three primary use paths: 1) **Use as-drawn** for applications where its cold-worked strength is sufficient. 2) **Machine, then quench & temper** for maximum strength (requires careful process control to manage distortion). 3) **Stress relieve, machine, then heat treat** for complex, high-precision parts. * **Machinability:** Not a free-machining steel. Requires rigid setups, appropriate cutting speeds/feeds, and ample coolant. Annealing is an option for extremely complex machining. * **Weldability:** **Weldable with strict procedures.** Mandatory preheat (200-300°C / 400-570°F), low-hydrogen electrodes, and post-weld heat treatment are required to avoid HAZ cracking and to restore properties. Welding is generally avoided on finished, hardened components. * **Comparison to Hot-Rolled 1536:** Offers superior surface finish, tighter tolerances, higher strength, better straightness, and more consistent machining performance. * **Comparison to 1144 Cold Drawn:** 1536 CD offers superior toughness, through-hardenability, and weldability, but lower machinability. 1144 CD is a high-strength free-machining steel; 1536 CD is a high-performance engineering steel. * **"H" Grade Available:** **AISI 1536H** is available in cold drawn form for applications requiring guaranteed hardenability bands (per SAE J1268), providing the highest level of predictability for critical heat-treated components. --- **Disclaimer:** This information is based on standard industry specifications. Actual properties may vary. For engineering applications, consult certified material test reports and conduct appropriate validation testing. The decision to use the material in the as-drawn condition or to apply subsequent heat treatment is a fundamental design choice impacting manufacturing process, cost, and final performance. -:- For detailed product information, please contact sales. -: AISI 1536 High Manganese Carbon Steel, Cold Drawn Bar Specification Dimensions Size： Diameter 20-1000 mm Length <5039 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. -: AISI 1536 High Manganese Carbon Steel, Cold Drawn Bar Properties -:- For detailed product information, please contact sales. -:
