Niagara LaSalle 1018 Cold Finished Steel Bar Product Information -:- For detailed product information, please contact sales. -: # **Product Introduction: Niagara LaSalle 1018 Cold Finished Steel Bar** **Niagara LaSalle 1018** is a **cold finished, low-carbon steel bar** produced to the stringent quality standards of Niagara LaSalle Corporation. It represents a premium, consistently reliable version of the ubiquitous AISI/SAE 1018 grade, processed through cold drawing to provide enhanced mechanical properties, superior surface finish, and tighter dimensional tolerances compared to hot-rolled equivalents. As a fundamental low-carbon steel, 1018 offers an exceptional balance of moderate strength, excellent ductility, and superior weldability and formability. Niagara LaSalle's production ensures high material consistency, excellent straightness, and a clean, scale-free surface, making it a preferred choice for high-volume, precision machining and fabrication where part quality and manufacturing efficiency are critical. --- ## **1. Chemical Composition (Per AISI/SAE 1018)** The composition adheres to the standard AISI/SAE 1018 specification, with Niagara LaSalle maintaining tight control to ensure batch-to-batch uniformity. | Element | Carbon (C) | Manganese (Mn) | Phosphorus (P) | Sulfur (S) | | :--- | :--- | :--- | :--- | :--- | | **Content** | 0.15 - 0.20 | 0.60 - 0.90 | ≤ 0.040 | ≤ 0.050 | **Key Characteristics of the Composition:** * **Low Carbon Content:** Provides excellent **ductility, toughness, and weldability**. It is not responsive to through-hardening by heat treatment but is ideal for case hardening (carburizing). * **Moderate Manganese:** Enhances strength and hardenability slightly compared to 1008/1010 grades, contributing to the improved properties from cold working. * **Standard Resulfurized/Rephosphorized:** Contains typical levels of phosphorus and sulfur; it is **not** a free-machining grade like 12L14. This balances machinability with good transverse mechanical properties. --- ## **2. Physical & Mechanical Properties (Cold Drawn Condition)** Cold drawing significantly improves the properties of the base hot-rolled steel. The values below are typical for Niagara LaSalle cold-drawn 1018 bars. | Property | Typical Value - Cold Drawn | **Advantage vs. Hot-Rolled** | | :--- | :--- | :--- | | **Yield Strength (0.2% Offset)** | **70,000 psi (483 MPa) Min** | **~50% higher** than hot-rolled (~50 ksi). | | **Tensile Strength** | 80,000 psi (552 MPa) Min | Significantly increased. | | **Elongation (in 2")** | **12%** (Minimum) | Maintains good ductility despite increased strength. | | **Reduction of Area** | 45% | | | **Hardness** | **126 - 179 HB** (71 - 88 HRB) | Increased surface hardness provides better wear resistance. | | **Machinability** | **~70% of 1212** | Good machinability for a non-leaded/low-sulfur grade; produces good surface finishes. | | **Surface Finish** | **63 - 125 µin Ra (1.6 - 3.2 µm)** | **Clean, smooth, scale-free surface** ideal for painting, plating, or direct use. | | **Dimensional Tolerance** | Meets **ASTM A108** precision tolerances (e.g., ±0.001" for smaller diameters). | **Tighter and more consistent** than hot-rolled, reducing machining allowance. | | **Straightness** | Excellent | Critical for automated machining and long shaft applications. | --- ## **3. Product Applications** Niagara LaSalle 1018 Cold Finished Bar is a versatile "workhorse" material used across virtually all manufacturing sectors for parts requiring a combination of strength, formability, and machinability. * **General Machined Components:** **Pins, shafts, bolts, studs, spindles, and axles** for light to moderate duty. * **Automotive & Transportation:** **Brackets, linkages, clamps, and non-critical structural parts.** * **Fabricated Structures & Frames:** Used for **weldments, frames, and supports** where its excellent weldability is a key advantage. * **Consumer Goods & Hardware:** Components for appliances, furniture, and tools. * **Case-Hardened Parts:** An excellent, economical substrate for **carburized or carbonitrided parts** like gears, cam lobes, and wear surfaces, where a hard case over a tough core is needed. --- ## **4. International & Equivalent Standards** As a fundamental grade, AISI/SAE 1018 has direct equivalents in all major international standards systems. | Standard System | Equivalent Grade | **Notes on Condition** | | :--- | :--- | :--- | | **AISI / SAE** | **1018** (Cold Drawn) | The direct U.S. standard. "Niagara LaSalle 1018" implies cold-finished quality. | | **ASTM** | **A108** (Standard for Steel Bars, Carbon, Cold-Finished) | This is the **governing material standard** for the cold-finished condition. | | **UNS** | G10180 | Unified Numbering System designation. | | **DIN (EN)** | **1.0402 (C22E / C22R)** | European equivalent. The "E" or "R" denotes suitability for engineering applications. | | **JIS** | **S20C** | Very close Japanese equivalent (nominal 0.20% C). | | **GB (China)** | **20# Steel** | Common Chinese designation. | | **ISO** | ISO 683-18: Type 1.0402 | International standard equivalent. | **Crucial Note:** While the chemistry is standard, specifying **"Niagara LaSalle 1018"** or **"1018 Cold Finished per ASTM A108"** ensures procurement of material with the enhanced mechanical properties, superior surface quality, and dimensional precision associated with a premium cold-drawn bar, as opposed to generic merchant bar stock. --- ## **5. Key Advantages & Considerations** **Advantages:** * **Excellent Weldability & Formability:** The low carbon content makes it ideal for welding (all processes) and cold bending/forming operations without pre-heating. * **Enhanced "As-Supplied" Properties:** Cold drawing provides higher strength, better surface finish, and tighter tolerances than hot-rolled stock, often reducing or eliminating rough machining steps. * **Cost-Effective & Readily Available:** A widely used, economical grade with excellent availability in a vast range of sizes and shapes (rounds, hexes, flats, squares). * **Good Base for Case Hardening:** The low carbon core remains tough after carburizing, making it a prime choice for surface-hardened components. **Considerations:** * **Not a Free-Machining Steel:** Machinability is good but not optimal for very high-volume screw machining; grades like 12L14 or 1215 are better for that purpose. * **Limited Through-Hardening:** Cannot be strengthened by quenching and tempering; its strength is fixed by the cold work. For higher core strength, consider medium-carbon grades like 1045 or 4140. * **Corrosion Susceptibility:** Like all non-stainless carbon steels, it requires protective coatings (paint, plating, galvanizing) for corrosion resistance. * **Anisotropic Properties:** Mechanical properties are directional; transverse ductility and impact strength are lower than longitudinal properties. --- **Disclaimer:** This overview describes typical properties. For critical applications, always consult the **official Niagara LaSalle material certification or data sheets** for the specific lot. Designers should account for the effect of further machining, welding, or forming on the final part properties, as these operations will alter the cold-worked state of the material. -:- For detailed product information, please contact sales. -: Niagara LaSalle 1018 Cold Finished Steel Bar Specification Dimensions Size： Diameter 20-1000 mm Length <5069 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. -: Niagara LaSalle 1018 Cold Finished Steel Bar Properties -:- For detailed product information, please contact sales. -:
