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. Chemical Composition (Standard Conformance)** | Element | Standard Range (%) | Key Function | | :--- | :--- | :--- | | **Carbon (C)** | 0.30 – 0.37 | Provides fundamental strength and hardenability. This level supports high strength after heat treatment while maintaining adequate toughness. | | **Manganese (Mn)** | 1.20 – 1.50 | **Primary Alloying Element.** Dramatically increases hardenability, allowing for effective through-hardening of substantial sections. Contributes significantly to strength and fine grain structure. | | **Phosphorus (P)** | ≤ 0.040 (max) | Residual element, minimized for good toughness. | | **Sulfur (S)** | ≤ 0.050 (max) | Residual element, kept low. **This is not a free-machining grade.** | | **Silicon (Si)** | 0.15 – 0.35 | Deoxidizer; solid solution strengthener. | | **Iron (Fe)** | Balance | Base element. | **Key International Standard Equivalents:** * **UNS:** G15360 * **AISI/SAE:** 1536 * **ASTM:** **A108** (Standard Specification for Steel Bar, Carbon and Alloy, Cold-Finished) * **ASTM:** A29 (General Requirements) * **DIN (Germany):** 1.1167 / 38Mn6 (Direct equivalent) * **EN (Europe):** 1.1167 / 38Mn6 --- ### **2. Typical Physical & Mechanical Properties (Cold Drawn Condition)** *Properties reflect the significant effect of cold work. Values are for the as-drawn state prior to any heat treatment.* | Property | Typical Value / Description | | :--- | :--- | | **Density** | 7.85 g/cm³ (0.284 lb/in³) | | **Tensile Strength** | 700 – 850 MPa (102 – 123 ksi) | | **Yield Strength (0.2% Offset)** | **580 – 730 MPa (84 – 106 ksi)** – *Primary benefit of cold drawing* | | **Elongation (in 50mm)** | 12% – 18% | | **Brinell Hardness (HB)** | 210 – 265 | | **Machinability (Comparison)** | Fair to Moderate (~40-45% of AISI 1212).

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.

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. -:
