AISI 1116 Steel, cold drawn Product Information -:- For detailed product information, please contact sales. -: ### **Product Data Sheet: AISI 1116 Steel, Cold Drawn** #### **1. Overview** AISI 1116 is a low-carbon, **re-phosphorized and re-sulfurized free-machining steel** supplied in the cold drawn condition. This material is engineered to provide **exceptional machinability** while maintaining a degree of formability superior to more heavily resulfurized grades. The combined addition of sulfur and a controlled amount of phosphorus significantly enhances chip-breaking characteristics during high-speed machining operations. The cold drawing process imparts a smooth, bright surface finish, tight dimensional tolerances, and increased yield strength through work hardening. AISI 1116 is a premier choice for high-volume production of precision, non-critical components where machining speed, surface finish, and tool life are paramount. --- #### **2. Chemical Composition (AISI/SAE Standard)** | Element | Content (%) | | :--- | :--- | | **Carbon (C)** | 0.14 - 0.20 | | **Manganese (Mn)** | 1.00 - 1.30 | | **Phosphorus (P)** | **0.07 - 0.12** | | **Sulfur (S)** | **0.16 - 0.23** | | **Iron (Fe)** | Balance | **Key Distinction:** This grade is defined by its dual additions of **phosphorus (P)** and **sulfur (S)** at specified ranges. Phosphorus increases strength and further improves machinability, while sulfur forms the chip-breaking manganese sulfide inclusions. This combination offers a balance of improved machinability over basic grades like 1018, but typically less than the extreme machinability of leaded steels like 12L14. --- #### **3. Typical Physical & Mechanical Properties (As Cold Drawn)** *Properties are for the cold drawn, work-hardened state.* | Property | Typical Value / Description | | :--- | :--- | | **Condition** | Cold Drawn (Work Hardened) | | **Tensile Strength** | **480 - 620 MPa (70 - 90 ksi)** | | **Yield Strength (0.2% Offset)** | **415 - 550 MPa (60 - 80 ksi)** | | **Elongation (in 50 mm)** | **~ 12 - 18%** | | **Hardness** | **85 - 100 HRB** (Rockwell B) / **~ 160 - 210 HB** | | **Machinability** | **Excellent (~135-150% of AISI 1212).** The combination of sulfur (MnS inclusions) and phosphorus provides superb chip formation, allowing for high cutting speeds, excellent surface finish, and extended tool life. | | **Surface Finish** | Smooth, bright, scale-free finish typical of cold drawing. | | **Dimensional Tolerance** | Tight, consistent tolerances per standards like ASTM A29 for cold-finished bars. | | **Cold Formability** | **Fair.** The higher manganese and phosphorus increase strength but reduce ductility compared to grades like 1018. Suitable for light to moderate bending and forming. | | **Weldability** | **Very Poor.** The high sulfur and phosphorus content make it extremely susceptible to **hot cracking (solidification cracking)** and porosity. **Welding is strongly discouraged.** | | **Hardenability** | **Very Low.** Not suitable for through-hardening. Can be case hardened (carburized) to create a hard wear surface over a machinable core. | --- #### **4. Key Characteristics & Metallurgical Behavior** * **Dual Free-Machining Additives:** The synergy of sulfur (MnS inclusions) and phosphorus (which increases hardness and brittleness of the ferrite matrix) creates one of the best non-leaded free-machining structures. * **Enhanced Strength from Cold Work & Chemistry:** The cold drawing and the higher manganese/phosphorus content provide a higher as-supplied strength compared to standard low-carbon free-machining steels like 1108. * **Bright Finish and Precision:** The cold drawing process ensures excellent surface quality and dimensional consistency, reducing the need for secondary finishing operations. * **Severe Welding Limitations:** The high levels of sulfur and phosphorus are severe contaminants for fusion welding, making this grade unsuitable for any welded fabrication. --- #### **5. Primary Product Applications** This product is ideal for high-volume, precision machining of components that will not be welded or subjected to high stress. * **High-Volume Screw Machine Parts:** **Complex shafts, fittings, connectors, bushings, and spacers** produced on Swiss-style and multi-spindle automatic screw machines. * **Automotive Non-Critical Components:** Various **sensor housings, electrical connectors, valve guides, and small brackets** where machinability is critical. * **Hydraulic & Pneumatic Fittings:** **Precision ferrules, couplings, and valve bodies** requiring excellent machined surface finishes for sealing. * **Fasteners & Hardware:** **Specialty bolts, set screws, and threaded components** manufactured via cold heading and secondary machining. * **General Machined Components:** Any part where minimizing machining time and maximizing tool life are primary economic drivers. --- #### **6. Relevant International & Industry Standards** | Standard System | Standard Designation | Title / Scope | | :--- | :--- | :--- | | **AISI / SAE / UNS (USA)** | **1116, SAE J403, UNS G11160** | Standard Free-Machining Steel Grade | | **ASTM (USA)** | **ASTM A29/A29M** | Specification for Steel Bars, Carbon and Alloy, Hot-Wrought and Cold-Finished | | **ASTM (USA)** | **ASTM A108** | Specification for Steel Bars, Carbon, Cold-Finished, Standard Quality | | **DIN / EN (Germany/EU)** | **1.0718 / 10S20** | EN 10087: Free-cutting steels.

Can undergo **light cold forming** (bending, coining) if necessary. 3. **Heat Treatment:** Generally not performed for through-hardening. Can be **stress relieved** (~260-315°C / 500-600°F) for dimensional stability or **carburized** for wear resistance on selected surfaces. 4. **Finishing:** An excellent substrate for **plating (zinc, nickel), painting, or anodizing** due to its smooth surface. 5. **Joining:** Use **mechanical fastening (threads, press fits)** or **adhesive bonding**. **Avoid fusion welding.** **Summary:** **AISI 1116 cold drawn is a high-performance, non-leaded free-machining steel.** It delivers an outstanding balance of **superb machinability, good strength, and excellent dimensional precision**, making it a cost-effective choice for the high-volume production of intricate components. Its value is realized through **dramatically reduced machining cycles, superior surface finishes, and lower total part cost**. While its weldability is non-existent and its applications are limited to non-structural roles, it remains a staple material in the precision machining, automotive, and fluid power industries where manufacturing efficiency is key. -:- For detailed product information, please contact sales. -: AISI 1116 Steel, cold drawn Specification Dimensions Size： Diameter 20-1000 mm Length <4924 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 1116 Steel, cold drawn Properties -:- For detailed product information, please contact sales. -:
