AISI 1117 Steel, as cold drawn, 16-22 mm (0.625-0.875 in) round Product Information -:- For detailed product information, please contact sales. -: ### **Product Introduction: AISI 1117 Steel, Cold Drawn, Round Bar (16-22 mm / 0.625-0.875 in)** **Overview** AISI 1117 is a popular low-carbon, free-machining steel known for its excellent balance of machinability, surface finish, and moderate strength. When supplied in the **cold drawn** condition, the material undergoes a precision forming process that enhances its mechanical properties and dimensional accuracy. This product, specifically in round bar form with diameters ranging from **16 mm to 22 mm (0.625 in to 0.875 in)**, is ideal for high-volume production of precision components requiring superior surface quality and tight tolerances. **Key Features & Benefits** * **Superior Machinability:** The addition of sulfur and manganese forms manganese sulfide inclusions, which act as chip breakers, allowing for faster machining speeds, longer tool life, and excellent surface finishes. * **Enhanced Strength & Surface Quality (Cold Drawn):** The cold drawing process increases tensile and yield strength through work-hardening while providing a smooth, scale-free surface ready for further processing. * **Good Consistency & Dimensional Accuracy:** Cold drawing ensures uniform cross-section, straightness, and precise diameters, reducing setup time and material waste in automated machining. * **Case Hardenability:** While not a through-hardening steel, AISI 1117 responds well to carburizing or cyaniding processes, creating a hard, wear-resistant surface over a tough, ductile core. --- ### **Technical Specifications** **1. Chemical Composition (Standard % by Weight)** | Element | Carbon (C) | Manganese (Mn) | Phosphorus (P) | Sulfur (S) | Iron (Fe) | | :--- | :--- | :--- | :--- | :--- | :--- | | **Content** | 0.14 - 0.20 | 1.00 - 1.30 | ≤ 0.040 | 0.08 - 0.13 | Balance | | **Role** | Provides core strength | Improves hardenability & works with S | Impurity (controlled) | **Key for machinability** | Base Metal | **2. Typical Physical & Mechanical Properties (Cold Drawn Condition)** * **Tensile Strength:** ≈ 540 - 620 MPa (78 - 90 ksi) * **Yield Strength (0.2% Offset):** ≈ 415 - 515 MPa (60 - 75 ksi) * **Elongation (in 50 mm):** ≈ 12% - 18% * **Hardness:** ≈ 163 - 201 Brinell (HB) * **Density:** 7.87 g/cm³ (0.284 lb/in³) * **Modulus of Elasticity:** 200 GPa (29,000 ksi) *(Note: Actual mechanical properties can vary slightly based on the final cold reduction ratio and the manufacturer's process.)* **3. International Standards & Equivalent Grades** AISI 1117 is recognized under various international standards. The cold drawn round bar product typically conforms to dimensional tolerances specified in standards like ASTM A29. | Standard | Grade/Designation | Remarks | | :--- | :--- | :--- | | **UNS (USA)** | G11170 | Unified Numbering System | | **ASTM (USA)** | ASTM A108 | Standard for Steel Bar, Carbon, Cold-Finished | | **SAE (USA)** | SAE 1117 | Original automotive standard | | **DIN (Germany)** | 1.0721 | Equivalent grade (11SMn30) | | **JIS (Japan)** | SUM22 | Very close equivalent, slightly higher S | --- ### **Primary Applications** This specific form of AISI 1117 (cold drawn, medium-diameter round) is extensively used in automated screw machines (Swiss-type, multi-spindle) and CNC lathes to produce precision parts, including: * **Automotive Components:** Bushings, set screws, clutch pins, knurl pins, spacers, and various non-critical fasteners. * **Industrial Parts:** Shafts, spindles, rollers, dowel pins, and hydraulic fittings where good machinability is paramount. * **Consumer Goods:** Components for appliances, hardware, and power tools. * **General Machined Parts:** Any high-volume component requiring excellent finish, consistent machining, and the potential for subsequent surface hardening. --- ### **Processing Considerations** * **Heat Treatment:** Commonly **carburized** to achieve a hard, wear-resistant surface (Rc 55-62) while maintaining a tough core. Not recommended for through-hardening. * **Weldability:** **Poor.** The high sulfur content leads to hot shortness and crack formation. Not suitable for fusion welding processes intended to carry load. * **Machining:** Performs exceptionally well with high-speed steel (HSS) or carbide tools. Use positive rake angles and adequate cutting fluids for optimal results. ### **Conclusion** Cold drawn AISI 1117 round bar in the 16-22 mm diameter range is a cost-effective, high-performance material for manufacturers prioritizing speed, surface finish, and dimensional precision in mass production. Its enhanced properties from cold drawing, combined with inherent free-machining characteristics, make it a **standard choice for precision-machined components** across automotive and general industries. -:- For detailed product information, please contact sales. -: AISI 1117 Steel, as cold drawn, 16-22 mm (0.625-0.875 in) round Specification Dimensions Size： Diameter 20-1000 mm Length <4931 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 1117 Steel, as cold drawn, 16-22 mm (0.625-0.875 in) round Properties -:- For detailed product information, please contact sales. -:
