Niagara LaSalle 1215 Cold Finished Steel Bar Product Information -:- For detailed product information, please contact sales. -: # **Product Introduction: Niagara LaSalle 1215 Cold Finished Steel Bar** **Niagara LaSalle 1215** is a premium-grade **cold finished, low-carbon, free-machining steel bar** specifically engineered to provide the **best possible combination of machinability and uniformity in cold forming operations** within the non-leaded free-cutting steel family. Produced under Niagara LaSalle's stringent quality standards, this material represents a refined variant of the classic 1212 grade, with modified sulfur and phosphorus levels that optimize both chip control and multi-directional ductility. As a balanced free-machining steel, 1215 is designed for applications requiring extensive machining *and* some degree of post-machining cold forming, such as knurling, swaging, or crimping, where the extreme brittleness of higher-sulfur grades like 1213 would be problematic. It offers a practical compromise, delivering excellent machining performance while retaining marginally better mechanical integrity. --- ## **1. Chemical Composition (Per AISI/SAE 1215)** The composition is carefully adjusted from the 1212 standard to enhance consistency and formability. | Element | Carbon (C) | Manganese (Mn) | Phosphorus (P) | Sulfur (S) | | :--- | :--- | :--- | :--- | :--- | | **Content** | 0.09 max | 0.75 - 1.05 | **0.04 - 0.09** | **0.26 - 0.35** | | *Key Difference vs. 1212* | Lower Max | Similar Range | **Lower: 0.04-0.09 vs. 0.07-0.12** | **Higher: 0.26-0.35 vs. 0.16-0.23** | | *Key Difference vs. 1213* | Lower Max | Similar Range | **Lower: 0.04-0.09 vs. 0.07-0.12** | Similar High Range | **Key Characteristics of the Composition:** * **High Sulfur, Controlled Phosphorus:** This is the defining balance: * **High Sulfur (0.26-0.35%):** Ensures excellent chip-breaking and good machinability via abundant MnS inclusions. * **Moderated Phosphorus (0.04-0.09%):** Lower than 1212/1213. Phosphorus is a potent solid-solution strengthener that increases brittleness. Reducing it slightly improves ductility, particularly in the transverse direction, allowing for limited cold forming after machining. * **Very Low Carbon:** Maximizes softness and machinability while minimizing hardening during cold work. * **Optimized for Combined Operations:** The chemistry is tailored for parts that are first machined and then subjected to light forming, providing better resistance to cracking during secondary operations than 1212 or 1213. --- ## **2. Physical & Mechanical Properties (Cold Drawn Condition)** The properties reflect its role as a ductility-enhanced free-machining steel. | Property | Typical Value - Cold Drawn | **Engineering Significance** | | :--- | :--- | :--- | | **Yield Strength (0.2% Offset)** | **60,000 - 70,000 psi (414 - 483 MPa)** | Similar to 1212; adequate for light-duty fastening and non-structural uses. | | **Tensile Strength** | 70,000 - 85,000 psi (483 - 586 MPa) | | | **Elongation (in 2")** | **12%** (Minimum, Longitudinal) | **Marginally better ductility than 1212/1213** due to lower phosphorus, offering slightly improved toughness. | | **Reduction of Area** | 25% | | | **Hardness** | **121 - 179 HB** (68 - 88 HRB) | Soft, ensuring low cutting forces and good tool life. | | **Machinability** | **~95-100% of 1212** | **Excellent, near-benchmark machinability.** May produce slightly longer chips than 1213 but with less tool abrasion. | | **Surface Finish (As-Drawn/Machined)** | **32 - 63 µin Ra (0.8 - 1.6 µm)** / Very Good | Provides very good machined surface quality. | | **Dimensional Tolerance** | Meets **ASTM A108** precision tolerances. | Essential for precision components. | | **Cold Formability** | **Fair (Best among 1212/1213/1215 series)** | Can withstand light knurling, rolling, or bending post-machining better than 1212 or 1213, due to lower phosphorus content. | | **Chip Characteristics** | Short to medium, easily broken chips | Good chip control suitable for automated machining. | --- ## **3. Product Applications** Niagara LaSalle 1215 Cold Finished Bar is ideal for components that require **high-speed machining followed by a secondary cold-forming operation**, where using a standard free-machining steel might lead to cracking. * **Complex Fasteners:** **Bolts, screws, and specialty fasteners** that are machined and then have heads formed, knurled, or crimped. * **Fittings & Connectors:** **Hydraulic fittings, compression fittings, and plumbing connectors** that are machined and later flared or swaged. * **Shafts & Pins:** **Small shafts, dowel pins, or rollers** that may be machined and then have grooves knurled or ends upset. * **Electrical Components:** **Terminals and connectors** requiring machining and subsequent bending or forming. * **General Screw Machine Parts:** Where the specific job has experienced cracking with 1212/1213 during secondary operations. --- ## **4. International & Equivalent Standards** AISI 1215 is a less common but specific grade. Its unique P/S balance makes finding direct chemical equivalents challenging. | Standard System | Equivalent / Comparable Grade | **Notes & Key Distinctions** | | :--- | :--- | :--- | | **AISI / SAE** | **1215** (Cold Drawn) | The direct U.S. standard, defined by high S and moderated P. | | **ASTM** | **A108** | Governing standard for the cold-finished condition. | | **UNS** | G12150 | Unified Numbering System. | | **DIN (EN)** | **No direct equivalent.** Closest is **1.0737 (11SMn30)**. | European grades do not typically replicate this specific P/S balance. 1.0737 has higher P (~0.09-0.13%), making it more like 1212. | | **ISO** | ISO 683-9: Type 1.0737 | The closest ISO standard, though not identical. | | **JIS** | **SUM22** | Japanese equivalent in application, but chemistry differs. | | **GB (China)** | **Y15** | Chinese free-cutting steel, similar in application. | | **Proprietary** | **Variants of 12L14** | For pure machinability without the need for secondary forming, leaded grades are often used. 1215 offers a non-leaded alternative with better formability. | **Key Distinction:** **1215 is the specialist grade within the non-leaded 12xx series for applications involving machining plus forming.** It fills the niche between the highly machinable but brittle 1213 and the more formable but less machinable 1117. --- ## **5. Key Advantages & Considerations** **Advantages:** * **Optimized for Machining + Forming:** Uniquely balances good machinability with the best cold formability in its series, reducing cracking in secondary operations. * **Excellent Machinability:** Maintains very high machining speeds and good tool life, close to the industry benchmark. * **Non-Leaded Composition:** Avoids the environmental, health, and plating challenges associated with leaded steels like 12L14. * **Consistent Performance:** Niagara LaSalle's production ensures uniform behavior for reliable high-volume manufacturing. **Considerations:** * **Lower Mechanical Strength:** Still a free-machining steel with low strength and poor toughness compared to non-resulfurized grades. * **Poor Weldability:** **Not weldable.** The high sulfur content prevents reliable welding. * **Limited Ductility:** While "better" than 1212/1213, its ductility is still very low by engineering standards. Severe forming is not possible. * **Corrosion Susceptibility:** Requires protective coatings. MnS inclusions can promote pitting. * **Less Common Grade:** May not be as readily available as 1212 or 12L14 from all distributors. --- **Disclaimer:** The properties listed are typical for cold-drawn 1215. This material is a specialized machining steel with limited mechanical utility. For critical applications, always consult **official Niagara LaSalle material certifications and technical data sheets**.
