AISI 1018 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 1018 Steel, Cold Drawn, 16-22 mm (0.625-0.875 in) Round Bar** **Overview** AISI 1018 is a versatile and widely used low-carbon steel known for its excellent combination of strength, ductility, and weldability. When supplied in the **cold drawn** condition as a round bar within the 16-22 mm (0.625-0.875 inch) diameter range, it offers significantly improved mechanical properties, tighter dimensional tolerances, and a superior surface finish compared to its hot-rolled counterpart. This makes it an ideal choice for precision machined components and structural applications requiring reliable performance. **Key Advantages of Cold Drawing:** * **Enhanced Strength & Hardness:** The cold drawing process work-hardens the material, increasing yield and tensile strength. * **Superior Surface Finish:** A smooth, scale-free surface is achieved, reducing the need for further finishing. * **Excellent Straightness & Dimensional Accuracy:** Tighter tolerances on diameter, roundness, and straightness are maintained. * **Good Machinability:** Despite increased hardness, AISI 1018 remains readily machinable, producing small, brittle chips. --- ### **1. Chemical Composition** The composition adheres to standard AISI 1018 specifications, ensuring consistent performance. | Element | Content (%) | Element | Content (%) | | :------ | :---------- | :------ | :---------- | | **Carbon (C)** | 0.15 - 0.20 | **Manganese (Mn)** | 0.60 - 0.90 | | **Phosphorus (P)** | ≤ 0.040 | **Sulfur (S)** | ≤ 0.050 | | **Iron (Fe)** | Balance | | | * **Low Carbon Content:** Provides excellent weldability and ductility. * **Manganese:** Enhances strength and hardenability. --- ### **2. Typical Mechanical & Physical Properties (Cold Drawn Condition)** Properties are indicative and can vary slightly based on the specific drawing process and final diameter. **Mechanical Properties:** * **Tensile Strength:** 440 - 550 MPa (64,000 - 80,000 psi) * **Yield Strength (0.2% Offset):** 370 - 480 MPa (54,000 - 70,000 psi) * **Elongation (in 50 mm / 2 in):** 15% - 25% * **Reduction of Area:** 40% - 50% * **Hardness (Brinell):** 126 - 180 HB * **Machinability (compared to 1212 steel):** ~70-78% **Physical Properties:** * **Density:** 7.87 g/cm³ (0.284 lb/in³) * **Melting Point:** ~1,510 °C (2,750 °F) * **Modulus of Elasticity:** 190 - 210 GPa (27,500 - 30,500 ksi) * **Thermal Conductivity:** ~51.9 W/m·K * **Coefficient of Thermal Expansion:** 11.7 x 10⁻⁶ /°C (20-100°C) --- ### **3. Product Applications** Cold drawn AISI 1018 round bars in this diameter range are fundamental materials in manufacturing and engineering due to their balance of properties. * **Precision Machined Parts:** Shafts, pins, bolts, studs, spindles, and axles. * **Automotive Components:** Gears, non-critical crankshafts, steering components, and hydraulic fittings. * **General Manufacturing:** Tool holders, jigs, fixtures, guide rods, and rollers. * **Construction & Hardware:** Forged or machined fasteners, connector rods, and general structural parts requiring good finish. * **Consumer Goods:** Parts for bicycles, furniture, and appliances. --- ### **4. Relevant International Standards** This product is recognized and specified under numerous international standards, ensuring global interoperability. * **AISI / SAE (USA):** AISI 1018, SAE J403 * **ASTM (USA):** ASTM A108 (Standard Specification for Steel Bar, Carbon and Alloy, Cold-Finished) * **UNS Number:** G10180 * **ISO (International):** ISO 683-18 (Heat-treatable steels, alloy steels and free-cutting steels — Part 18: Bright steel products) - Similar grades include C15E4, 1.1141. * **DIN (Germany):** 1.0402 / CK15 (Similar grade, minor compositional differences) * **JIS (Japan):** SWRCH18K (Similar free-cutting grade), S15C (Similar carbon steel for machine structural use) * **EN (European):** EN 10277-2 (Bright steel products — Technical delivery conditions — Part 2: Steels for general engineering purposes) - Grade 1.0402. --- ### **5. Additional Processing & Considerations** * **Heat Treatment:** Readily responds to carburizing or case hardening, creating a hard, wear-resistant surface over a tough, ductile core. * **Welding:** Excellent weldability using all standard methods (SMAW, GMAW, GTAW) without pre- or post-heating. However, welding can anneal the cold-worked areas, locally reducing strength. * **Machining:** Performs well with standard high-speed steel or carbide tools. Recommended to use positive rake angles and adequate cooling. * **Corrosion Resistance:** Like all mild steels, it has limited corrosion resistance and requires protective coatings (plating, painting, galvanizing) for exposed environments. **Conclusion:** Cold drawn AISI 1018 steel round bar in the 16-22 mm diameter range is a high-quality, general-purpose engineering material. Its enhanced properties from cold drawing, combined with its ease of fabrication and wide international standardization, make it a reliable and cost-effective choice for a vast array of mechanical and structural applications demanding precision, strength, and good surface quality. -:- For detailed product information, please contact sales. -: AISI 1018 Steel, as cold drawn, 16-22 mm (0.625-0.875 in) round Specification Dimensions Size： Diameter 20-1000 mm Length <5433 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 1018 Steel, as cold drawn, 16-22 mm (0.625-0.875 in) round Properties -:- For detailed product information, please contact sales. -:
