AISI 1561 Steel Composition Spec (UNS G15610) Product Information -:- For detailed product information, please contact sales. -: ### **Product Introduction: AISI 1561 / UNS G15610 High Manganese Carbon Steel** **1. Overview** AISI 1561 (UNS G15610) is a high-manganese, medium-to-high carbon steel grade renowned for its exceptional combination of high strength, good wear resistance, and excellent toughness. It belongs to the family of "1561" series steels, which are characterized by their significant manganese content (typically 1.00-1.30%). This alloying composition promotes deep hardenability, allowing the steel to achieve high strength and hardness through proper heat treatment, particularly in larger cross-sections. It is widely used in applications demanding durability under heavy stress and abrasive conditions. **2. Chemical Composition (Weight %)** The standard chemical composition is defined as follows: | Element | Minimum (%) | Maximum (%) | | :-------- | :---------- | :---------- | | Carbon (C) | 0.55 | 0.65 | | Manganese (Mn) | 1.00 | 1.30 | | Phosphorus (P) | - | 0.040 | | Sulfur (S) | - | 0.050 | | Silicon (Si) | 0.15 | 0.30 | | Iron (Fe) | Balance | Balance | *(Note: Minor residual elements may be present within allowable limits.)* **3. Physical & Mechanical Properties (Typical, Annealed or As-Rolled Condition)** Properties can vary significantly with heat treatment. The following are typical values for normalized or hot-rolled material. * **Density:** 7.85 g/cm³ (0.284 lb/in³) * **Melting Point:** ~1420-1460°C (2590-2660°F) * **Modulus of Elasticity:** 200-210 GPa (29-30 x 10⁶ psi) * **Poisson's Ratio:** 0.29 * **Thermal Conductivity:** ~48 W/m·K (at 100°C) * **Machinability:** ~55% (compared to 100% for AISI 1212 free-machining steel). Fair to good machinability in the annealed state. **Mechanical Properties (Heat Treated - Quenched & Tempered)** When properly quenched and tempered, AISI 1561 achieves superior mechanical properties. * **Tensile Strength:** 850 - 1000 MPa (123 - 145 ksi) * **Yield Strength (0.2% Offset):** 650 - 800 MPa (94 - 116 ksi) * **Elongation (in 50mm):** 15% - 22% * **Reduction in Area:** 40% - 50% * **Hardness (Brinell):** 248 - 302 HB (Approx. 25 - 32 HRC, can be higher with specific treatments) * **Impact Toughness (Charpy V-notch):** Good to excellent, dependent on tempering temperature. **4. Product Applications** AISI 1561 is primarily selected for high-strength, wear-resistant components, especially where good core toughness is required. Typical applications include: * **Automotive & Transportation:** Axle shafts, high-strength bolts, heavy-duty gears, clutch components, and forged crankshafts. * **Agricultural Machinery:** Gears, shafts, tillage tools, and drive components subjected to shock loads. * **Construction & Mining Equipment:** Bucket pins, track links, rollers, and other high-stress, abrasion-prone parts. * **General Machinery:** High-strength fasteners, couplings, spindles, and other critical forged or machined parts. * **Railroad Components:** Certain types of couplers, yokes, and other high-integrity forgings. **5. International Standards & Cross-References** AISI 1561 / UNS G15610 is recognized under various international standards with closely equivalent grades. | Standard | Designation | Remarks | | :-------------- | :-------------- | :-------------------------------------------- | | **UNS** | G15610 | Unified Numbering System | | **ASTM** | A510 (Grade 1561) | Standard Specification for General Requirements for Wire Rods and Coarse Round Wire. | | **SAE / AMS** | SAE J403 (1561) | SAE Standard Chemical Composition. | | **FED / QQ** | QQ-S-635 (Class 4, Grade F) | Federal specification for steel bars, often references 1561-type composition. | | **DIN (Germany)** | ~1.0904 / 38Mn6 | Similar but not identical composition; European counterpart. | | **ГОСТ (Russia)** | ~60Г | Russian grade with similar C-Mn characteristics. | *(Note: Direct equivalents may not exist in all standards; chemical composition ranges should be compared for critical applications.)* **6. Heat Treatment** AISI 1561 responds well to standard heat treatments: * **Annealing:** Performed to soften for machining. * **Normalizing:** To refine grain structure. * **Quenching & Tempering:** The primary strengthening process. It is typically austenitized between 830-850°C (1525-1560°F), quenched in oil (or water for maximum hardness in larger sections), and tempered at temperatures ranging from 400-650°C (750-1200°F) to achieve the desired balance of strength and toughness. **Conclusion** AISI 1561 (UNS G15610) is a versatile and economical high-strength alloy steel, offering an outstanding balance of toughness, wear resistance, and hardenability. Its high manganese content ensures these properties are maintained in larger-sized components. It remains a material of choice for engineers designing heavily loaded parts in the automotive, agricultural, and heavy equipment industries. -:- For detailed product information, please contact sales. -: AISI 1561 Steel Composition Spec (UNS G15610) Specification Dimensions Size： Diameter 20-1000 mm Length <5052 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 1561 Steel Composition Spec (UNS G15610) Properties -:- For detailed product information, please contact sales. -:
