The cold-drawing process enhances its mechanical properties, surface finish, and dimensional consistency compared to hot-rolled stock. With a carbon content slightly higher than 1010, it provides a better balance of strength and chip-breaking characteristics, making it one of the most popular choices for high-volume production of parts on automatic screw machines and CNC lathes. It is a versatile, cost-effective material for components requiring good finish, precise tolerances, and reliable performance. --- ### **1. Chemical Composition (Typical % by Weight, AISI/SAE Standard)** The composition of AISI 1012 is optimized for manufacturability, particularly machining. | Element | Content (%) | Role & Effect | | :--- | :--- | :--- | | **Carbon (C)** | 0.10 - 0.15 | **Optimal for machinability.** This range provides enough carbon to form fragmented chips (improving over gummy, low-carbon steels) while keeping weldability excellent and preventing excessive tool wear. | | **Manganese (Mn)** | 0.30 - 0.60 | Contributes to strength and hardenability. Standard range for mild steel. | | **Phosphorus (P)** | 0.040 max | Impurity; controlled for formability. | | **Sulfur (S)** | 0.050 max | Often maintained at the mid-to-high end of the range to aid machinability by promoting chip brittleness. | | **Iron (Fe)** | Balance | Primary constituent. | --- ### **2. Physical & Mechanical Properties (Cold-Drawn Condition)** **A. Physical Properties** * **Density:** 7.87 g/cm³ (0.284 lb/in³) * **Elastic Modulus (E):** 200 GPa (29,000 ksi) * **Poisson's Ratio:** 0.29 * **Thermal Conductivity:** ~60 W/m·K * **Electrical Resistivity:** ~11.8 μΩ·cm **B. Mechanical Properties (Typical for Cold-Drawn Bar)** *Properties are directional (anisotropic) due to cold work.* * **Yield Strength (0.2% Offset):** **415 - 620 MPa (60 - 90 ksi)** *[Significantly higher than hot-rolled]* * **Tensile Strength:** **520 - 725 MPa (75 - 105 ksi)** * **Elongation in 50 mm:** **8% - 15%** (Adequate for handling and light forming). * **Hardness (Brinell):** **160 - 220 HB** * **Surface Finish:** Smooth, bright, and scale-free. Ideal for plating, painting, or as-machined appearance. * **Dimensional Tolerance:** Conforms to tight **ASTM A29** cold-drawn tolerances. * **Machinability:** **Excellent.** Often used as a **standard reference (100% rating)** in machinability comparisons for carbon steels. The carbon content promotes the formation of small, broken chips, leading to better surface finish, longer tool life, and higher production speeds. * **Hardenability:** **Very Low.** Not suitable for through-hardening. Can be case hardened (carburized) for wear resistance. --- ### **3. Product Applications** Cold-drawn AISI 1012 is a premier material for mass-produced, precision machined components. * **Screw Machine Products:** The **primary application.** Used for a vast array of parts produced on automatic lathes: bushings, spacers, sleeves, fittings, connectors, and knobs. * **Fasteners and Hardware:** High-quality bolts, nuts, studs, and pins (often cold-headed from wire stock). * **Shafts and Pins:** Light-duty shafts, dowel pins, hinge pins, and guide rods where a smooth finish is beneficial. * **Automotive Components:** Fuel system parts, linkage components, brake pins, and various under-hood brackets. * **Hydraulic and Pneumatic Fittings:** Connectors, adapters, and valve bodies. * **Consumer Goods:** Parts for appliances, tools, and furniture requiring good machined finish. --- ### **4. International Standards & Designations** | Standard System | Designation | Notes / Key Comparison | | :--- | :--- | :--- | | **SAE / AISI (USA)** | **SAE 1012 / AISI 1012** | Standard designation. | | **UNS (USA)** | **G10120** | Unified Numbering System. | | **ASTM (USA)** | **ASTM A108** | Governing specification for cold-finished carbon steel bars. | | **DIN / EN (Germany/EU)** | **C15D (1.1141), C15E (1.1141)** | **C15D** (bright steel) or **C15E** (engineering steel) are close equivalents with similar carbon content for machining. | | **JIS (Japan)** | **S12C, SWRCH12A** | **S12C** for steel bars (JIS G4051); **SWRCH12A** for cold heading wire rod (JIS G3507). | | **GB (China)** | **15, ML15** | **15** is a common grade; **ML15** designates cold heading quality. | | **ISO** | **ISO 683-18: G15** | For bright steel products. | --- ### **Processing & Design Considerations** 1. **Machining Advantage:** The key reason for specifying 1012 over 1010 is its improved chip breakability and surface finish in machining operations, leading to lower per-part cost in high-volume production. 2. **Stress Relieving:** If secondary cold forming is required, low-temperature stress relief can mitigate springback. 3. **Weldability:** **Excellent.** However, welding will anneal the cold-worked HAZ, creating a localized soft zone. 4. **Case Hardening:** A viable secondary process for parts requiring wear-resistant surfaces (e.g., gears, cam followers). 5. **Economic Efficiency:** The combination of excellent machinability and cold-drawn precision minimizes machining time, tool wear, and scrap rates. ### **Summary** **Cold-drawn AISI 1012 is the benchmark material for economical, high-quality machined components.** It masterfully balances enhanced strength from cold work with **exceptional machinability**, making it the default choice for screw machine shops and precision CNC turning. Its bright finish and tight tolerances reduce or eliminate secondary finishing operations. While very similar to 1010, its slightly higher carbon content provides a tangible benefit in manufacturing productivity. Governed by **ASTM A108** and recognized globally under equivalents like **JIS S12C** and **DIN C15D**, it is a universally trusted, standardized material that delivers consistent performance and value in mass production. -:- For detailed product information, please contact sales. -: AISI 1012 Steel, cold drawn Specification Dimensions Size： Diameter 20-1000 mm Length <4746 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 1012 Steel, cold drawn Properties -:- For detailed product information, please contact sales. -:
