Product Overview** AISI 1021 is a standard low-carbon steel grade with a marginally higher manganese content than AISI 1020, providing a subtle enhancement in hardenability and strength. In its **Cold Drawn** condition, the hot-rolled bar is processed through a series of dies at room temperature. This cold working operation imparts significant improvements in dimensional accuracy, surface finish, and mechanical properties via strain hardening. AISI 1021 Cold Drawn steel is a premium-quality material engineered for applications requiring tight tolerances, excellent machinability, and a superior surface finish for precision components. ## **2. Key Features & Benefits of Cold Drawing** * **Precise Dimensional Control:** Achieves tight diameter tolerances (e.g., to ASTM A108 standards) and excellent straightness, reducing machining allowance and material waste. * **Enhanced Surface Quality:** Produces a smooth, bright, and scale-free surface finish, often suitable for applications without additional finishing. * **Improved Mechanical Properties:** The cold working process increases tensile strength, yield strength, and hardness compared to the hot-rolled or annealed state, providing a better strength-to-weight ratio. * **Superior Machinability:** The uniform microstructure and consistent hardness resulting from cold drawing facilitate predictable chip formation, extended tool life, and excellent surface finishes during machining. * **Good General Fabricability:** Retains good weldability and formability characteristic of low-carbon steels, though cold worked material may exhibit slight anisotropy. ## **3. Standard Chemical Composition (Weight %)** | Element | AISI 1021 Specification | Typical Analysis | | :--------------- | :---------------------- | :--------------- | | **Carbon (C)** | 0.18 - 0.23 | 0.20 | | **Manganese (Mn)**| 0.60 - 0.90 | 0.75 | | **Phosphorus (P)**| ≤ 0.040 | 0.010 | | **Sulfur (S)** | ≤ 0.050 | 0.025 | | **Iron (Fe)** | Balance | Balance | *Note: The defining difference from AISI 1020 is the elevated manganese range (0.60-0.90%), which offers slightly better hardenability and strength potential.* ## **4. Typical Mechanical Properties (Cold Drawn Condition)** *Properties are representative and vary based on the degree of cold reduction (drawing practice).* | Property | Metric Value | Imperial Value | | :--------------------------------- | :-------------------- | :-------------------- | | **Tensile Strength** | 480 - 620 MPa | 69,600 - 89,900 psi | | **Yield Strength (0.2% Offset)** | 415 - 550 MPa | 60,200 - 79,800 psi | | **Elongation in 50 mm (2 in)** | 10% - 18% | 10% - 18% | | **Hardness** | 80 - 95 HRB | 80 - 95 HRB | | **Modulus of Elasticity** | 190 - 210 GPa | 27,500 - 30,500 ksi | | **Machinability (Relative)** | **Very Good (~75%)** | (AISI 1212 = 100%) | ## **5. Primary Applications** AISI 1021 Cold Drawn steel is widely used in the manufacture of precision parts that benefit from its enhanced properties and finish. * **Shafts and Axles:** For automotive, agricultural, and general machinery applications requiring good strength and wear resistance. * **Precision Pins and Bushings:** Dowel pins, hinge pins, and guide bushings where dimensional accuracy is critical. * **Fasteners and Studs:** High-quality bolts, studs, and threaded rods requiring consistent mechanical properties. * **General Machined Components:** Gears (prior to heat treatment), sprockets, couplings, and hydraulic cylinder parts. * **Automotive Components:** Steering components, linkage parts, and brake system pins. * **Tooling and Fixturing:** Components for jigs, fixtures, and dies requiring wear resistance and stability. ## **6. Conforming International Standards** This product is equivalent to or supplied under the following international standards for cold-finished steel bars. * **AISI (USA):** AISI 1021 * **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 G10210 * **DIN (Germany):** 1.0406 / C18 (Close equivalent; Ck18 for case-hardening) * **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. * **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. Post-weld heat treatment may be considered for critical applications. * **Heat Treatment:** Responds well to **case hardening** processes like carburizing or carbonitriding. The cold-drawn condition is often used as-is for parts requiring moderate strength, but annealing may be performed prior to severe forming or machining operations where maximum ductility is needed. * **Stress Relieving:** For parts requiring high dimensional stability after heavy machining, a low-temperature stress relief (approx. 260-315°C / 500-600°F) can be applied to reduce internal stresses without significantly altering mechanical properties. ## **8. Availability & Supply** * **Form:** Primarily supplied as straight-length **round bars**. Square and hex bars may also be available. * **Condition:** **Cold Drawn (CD)** or **Cold Finished (CF)**. * **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. For applications demanding the highest dimensional stability under stress, specifying a **stress-relieved** cold drawn product is recommended. Certified test reports (MTRs) should be requested for critical applications. -:- For detailed product information, please contact sales. -: AISI 1021 Steel, cold drawn Specification Dimensions Size： Diameter 20-1000 mm Length <5456 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 1021 Steel, cold drawn Properties -:- For detailed product information, please contact sales. -:
