Product Overview** AISI 1022 is a standard low-carbon steel grade characterized by a balanced carbon content and moderate manganese, offering a reliable combination of strength, ductility, and excellent manufacturability. In its **Cold Drawn (CD)** condition, the hot-rolled bar is processed through precision dies at room temperature, significantly enhancing its dimensional accuracy, surface finish, and mechanical properties via strain hardening. Supplied in the diameter range of **19 mm to 32 mm (0.75 to 1.25 inches)**, this product is engineered for applications demanding tight tolerances, superior surface quality, and consistent, improved mechanical properties for precision-machined components and high-quality fastener stock. ## **2. Key Features & Benefits of Cold Drawing** * **Precision Dimensional Control:** Achieves excellent diameter consistency, straightness, and roundness with tight commercial tolerances (typically to ASTM A108 standards), reducing machining waste and improving assembly fit. * **Enhanced Surface Quality:** Produces a smooth, bright, and virtually scale-free surface, ideal for applications where aesthetics are important or for plating/painting with minimal preparation. * **Improved Mechanical Properties:** The cold working process increases tensile strength, yield strength, and hardness compared to the hot-rolled state, offering a better strength-to-ductility balance for structural parts. * **Superior and Consistent Machinability:** The uniform microstructure and consistent hardness resulting from controlled cold drawing lead to predictable chip formation, extended tool life, and excellent surface finishes during machining. * **Good General Fabricability:** Retains the good weldability and formability inherent to low-carbon steels, though some anisotropy may be present due to the drawing process. ## **3. Standard Chemical Composition (Weight %)** | Element | AISI 1022 Specification | Typical Analysis | | :--------------- | :---------------------- | :--------------- | | **Carbon (C)** | 0.18 - 0.23 | 0.20 | | **Manganese (Mn)**| 0.70 - 1.00 | 0.85 | | **Phosphorus (P)**| ≤ 0.040 | 0.010 | | **Sulfur (S)** | ≤ 0.050 | 0.025 | | **Iron (Fe)** | Balance | Balance | *Note: The manganese range is slightly higher than AISI 1020, providing marginally better hardenability and strength potential.* ## **4. Typical Mechanical Properties (Cold Drawn Condition)** *Properties are representative for the specified diameter range and vary with the degree of cold reduction.* | Property | Metric Value | Imperial Value | | :--------------------------------- | :-------------------- | :-------------------- | | **Tensile Strength** | 490 - 630 MPa | 71,000 - 91,400 psi | | **Yield Strength (0.2% Offset)** | 430 - 570 MPa | 62,400 - 82,700 psi | | **Elongation in 50 mm (2 in)** | 10% - 17% | 10% - 17% | | **Hardness** | 85 - 100 HRB | 85 - 100 HRB | | **Modulus of Elasticity** | 190 - 210 GPa | 27,500 - 30,500 ksi | | **Machinability (Relative)** | **Very Good (~74%)** | (AISI 1212 = 100%) | ## **5. Primary Applications** This cold-drawn product is widely used in the manufacture of precision parts that benefit from its enhanced properties and finish. * **General Machined Shafts and Pins:** For automotive, agricultural, and general machinery applications requiring good strength and dimensional accuracy. * **Fasteners and Studs:** High-quality bolts, studs, set screws, and threaded rods requiring consistent mechanical properties and good surface finish. * **Hydraulic and Pneumatic Components:** Piston rods, valve stems, and cylinder parts where surface integrity is important. * **Automotive Components:** Steering linkage parts, brake system components, and transmission shafts. * **Precision Bushings and Dowel Pins:** Where close-tolerance fit and wear resistance are required. * **Tooling and Fixturing:** Components for jigs, fixtures, and dies requiring stability and good machinability. ## **6. Conforming International Standards** This product is equivalent to or supplied under the following international standards for cold-finished steel bars. * **AISI (USA):** AISI 1022 * **ASTM (USA):** **ASTM A108** (Standard Specification for Steel Bar, Carbon and Alloy, Cold-Finished) * **SAE (USA):** SAE J403, SAE J412 (Chemical Compositions) * **UNS (USA):** UNS G10220 * **DIN (Germany):** 1.0406 / C18 or 1.1151 / C22 (Close equivalents) * **JIS (Japan):** JIS S20C (Similar grade for machine structural use) * **ISO (International):** ISO 683-18 (Designation for non-alloy quality steel) ## **7. Fabrication & Processing Notes** * **Machining:** **Excellent machinability.** The cold-drawn condition provides an ideal starting point for turning, milling, and drilling operations. Consistent hardness ensures predictable tool wear and good chip control. * **Welding:** Good weldability using standard methods (SMAW, GMAW, GTAW). However, the heat from welding will anneal the cold-worked area in the Heat-Affected Zone (HAZ), resulting in a localized loss of strength and hardness. For critical applications, post-weld heat treatment may be considered. * **Heat Treatment:** Responds well to **case hardening** processes like carburizing. The cold-drawn condition can be used as-is for parts requiring moderate strength, but annealing may be performed prior to severe forming operations. Stress relieving (~315-425°C) is recommended before heavy machining to prevent distortion. * **Forming:** Moderate cold forming is possible, but material will exhibit higher yield strength and lower elongation compared to annealed stock. ## **8. Availability & Supply** * **Form:** Straight length, round bar. * **Diameter Range:** **19 mm to 32 mm (0.75 to 1.25 inches)**. * **Condition:** **Cold Drawn (CD)** or **Cold Finished, Bright**. * **Surface Finish:** Bright, smooth finish typical of cold drawing. * **Tolerances:** Supplied to standard cold-drawn tolerances (e.g., ASTM A108). --- **Disclaimer:** The information provided is for reference purposes. Mechanical properties are dependent on the specific cold reduction ratio and may vary between manufacturers. Users are responsible for validating the material's suitability for their specific application, including considerations of the potential for directional properties and the effects of welding. Certified test reports (MTRs) should be requested for critical applications. For applications demanding the highest dimensional stability under stress, specifying a **stress-relieved** cold drawn product is recommended. -:- For detailed product information, please contact sales. -: AISI 1022 Steel, cold drawn round (19 - 32 mm) Specification Dimensions Size： Diameter 20-1000 mm Length <5463 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 1022 Steel, cold drawn round (19 - 32 mm) Properties -:- For detailed product information, please contact sales. -:
