Niagara LaSalle 1212 Cold Finished Steel Bar Product Information -:- For detailed product information, please contact sales. -: # **Product Introduction: Niagara LaSalle 1212 Cold Finished Steel Bar** **Niagara LaSalle 1212** is a premium-grade **cold finished, low-carbon, free-machining steel bar** specifically engineered for maximum machining efficiency in high-volume production. Produced to the stringent quality standards of Niagara LaSalle Corporation, this material represents the optimal balance of exceptional machinability, good dimensional stability, and adequate mechanical properties for a wide range of non-critical components. As the industry **benchmark for machinability** (rated at 100% in standard comparisons), AISI/SAE 1212 is a rephosphorized and resulfurized steel designed to deliver superior chip-breaking characteristics, extended tool life, and excellent surface finishes. Niagara LaSalle's cold finishing process enhances these attributes while providing improved mechanical properties and tighter dimensional tolerances compared to hot-rolled material, making it the preferred choice for screw machine products and precision-machined parts. --- ## **1. Chemical Composition (Per AISI/SAE 1212)** The composition is precisely controlled to optimize chip formation while maintaining consistency in production. | Element | Carbon (C) | Manganese (Mn) | Phosphorus (P) | Sulfur (S) | | :--- | :--- | :--- | :--- | :--- | | **Content** | 0.13 max | 0.70 - 1.00 | 0.07 - 0.12 | 0.16 - 0.23 | **Key Characteristics of the Composition:** * **Ultra-Low Carbon with Dual Additives:** This specific combination creates the ultimate free-machining structure: * **High Phosphorus (P):** Increases chip brittleness, promoting short, broken chips. * **High Sulfur (S):** Forms abundant manganese sulfide (MnS) inclusions that act as internal lubricants and chip breakers. * **Free-Machining Optimization:** The controlled levels of P and S work synergistically to produce **exceptionally favorable chip formation** during high-speed machining operations. * **Consistent Manganese:** Maintained in a range sufficient to form MnS inclusions while providing basic strength characteristics. --- ## **2. Physical & Mechanical Properties (Cold Drawn Condition)** Cold drawing provides enhanced properties while maintaining the material's legendary machinability. | Property | Typical Value - Cold Drawn | **Engineering Significance** | | :--- | :--- | :--- | | **Yield Strength (0.2% Offset)** | **60,000 - 70,000 psi (414 - 483 MPa)** | Adequate strength for many non-structural applications. | | **Tensile Strength** | 70,000 - 85,000 psi (483 - 586 MPa) | | | **Elongation (in 2")** | **10%** (Minimum) | Limited ductility due to inclusion content, characteristic of free-machining steels. | | **Hardness** | **121 - 179 HB** (68 - 88 HRB) | Soft structure optimized for cutting rather than wear resistance. | | **Machinability** | **100% of 1212 (Industry Benchmark)** | **Unsurpassed machinability** among standard steel grades. Enables maximum cutting speeds, feeds, and superior surface finishes. | | **Surface Finish (As-Drawn)** | **32 - 63 µin Ra (0.8 - 1.6 µm)** | Clean, scale-free surface ready for precision machining. | | **Dimensional Tolerance** | Meets **ASTM A108** precision tolerances. | Essential for high-volume screw machine production with minimal setup adjustment. | | **Straightness** | Excellent | Critical for automated feeding in screw machines. | | **Chip Characteristics** | Short, easily broken chips | Reduces machine downtime for chip clearing and improves operator safety. | --- ## **3. Product Applications** Niagara LaSalle 1212 Cold Finished Bar is the quintessential material for high-volume production of components where **machining speed, tool life, and surface finish are paramount**, and high mechanical strength is not a primary requirement. * **Screw Machine Products:** **Nuts, bolts, screws, studs, fittings, and connectors** produced on automatic screw machines at maximum speeds. * **Electrical & Electronic Components:** **Terminals, connectors, and small hardware** requiring precision machining. * **Plumbing & Fluid Handling:** **Fittings, valve bodies, and connectors** for low-pressure systems. * **General Hardware:** **Brackets, spacers, washers, pins, and shafts** for consumer products and light industrial applications. * **Prototype & R&D Work:** Ideal for quickly machining prototypes and fixtures due to its easy machinability. --- ## **4. International & Equivalent Standards** AISI 1212 has close functional equivalents in other standards systems, though exact compositional matches vary. | Standard System | Equivalent / Comparable Grade | **Notes & Key Distinctions** | | :--- | :--- | :--- | | **AISI / SAE** | **1212** (Cold Drawn) | The industry standard for free-machining steel. | | **ASTM** | **A108** | Governing standard for the cold-finished condition. | | **UNS** | G12120 | Unified Numbering System. | | **DIN (EN)** | **1.0718 (11SMnPb30)** | European free-cutting steel. Note: This grade contains lead for even better machinability. The non-leaded equivalent is **1.0737 (11SMn30)**. | | **ISO** | ISO 683-9: Type 1.0718 | International standard for free-cutting steels. | | **JIS** | **SUM22** or **SUM22L** | Japanese free-cutting steels with similar sulfur content. | | **GB (China)** | **Y12** or **Y15** | Chinese free-cutting steel grades. | | **Proprietary** | **La-Led® (12L14)** | Niagara LaSalle's leaded free-machining steel with even better machinability than 1212. | **Important Distinction:** While **12L14** (leaded) offers slightly better machinability, **1212** is preferred for applications where lead content must be avoided due to environmental, health, or regulatory concerns, or where subsequent plating processes are sensitive to lead. --- ## **5. Key Advantages & Considerations** **Advantages:** * **Unmatched Machinability:** The benchmark material for high-speed, high-volume machining operations. * **Superior Surface Finish:** Produces excellent as-machined surface quality with minimal effort. * **Extended Tool Life:** Significantly reduces tool wear compared to non-free-machining steels. * **Excellent Chip Control:** Produces small, broken chips that are easy to manage, enhancing safety and reducing downtime. * **Cost-Effective Production:** Lower machining costs per part due to higher speeds, longer tool life, and reduced scrap rates. **Considerations:** * **Low Mechanical Strength:** Not suitable for highly stressed or structural applications. * **Poor Weldability:** **Not weldable.** The high sulfur and phosphorus content guarantee cracking. * **Very Low Ductility & Toughness:** Brittle, especially in transverse directions. Unsuitable for cold forming or impact loading. * **Corrosion Susceptibility:** Requires protective coatings for corrosion resistance. Inclusions can act as corrosion initiation sites. * **Anisotropic Properties:** Severe directionality of properties; transverse strength and ductility are very poor. --- **Disclaimer:** The properties listed are typical for cold-drawn 1212.
