A flange—also referred to as a flange plate or rim—is a component used to connect shafts to one another, or, more commonly, to join the ends of pipes. Flanges are also utilized at the inlet and outlet ports of equipment to facilitate connections between two devices—for instance, the flange on a speed reducer. A "flange connection" or "flanged joint" refers to a detachable joint assembly comprising three interconnected elements—a flange, a gasket, and bolts—that together form a sealed structural unit. In the context of piping systems, a "pipe flange" specifically denotes a flange used for plumbing within the installation; when applied to equipment, it refers to the inlet or outlet flange of that specific device. Flanges feature a series of holes through which bolts are inserted to securely fasten the two flanges together, while a gasket placed between the flanges ensures a leak-proof seal. Flanges are broadly categorized into three types: threaded (screw-in) flanges, welded flanges, and clamp-type flanges. Flanges are invariably used in pairs; threaded flanges are suitable for low-pressure piping applications, whereas welded flanges are required for systems operating at pressures exceeding 4 kilograms per square centimeter. A sealing gasket is inserted between the two flange plates, which are then firmly secured using bolts. The thickness of a flange—as well as the specifications of the bolts used to fasten it—vary depending on the specific pressure rating required for the application. When connecting equipment such as water pumps or valves to piping systems, the corresponding connection points on these devices are often manufactured in the shape of a matching flange; this method of attachment is also referred to as a "flange connection." Generally, any connecting component that utilizes bolts to join and seal the perimeters of two flat surfaces—such as the joints in ventilation ducts—is termed a "flange"; such components may collectively be classified as "flange-type parts." However, since such a connection often constitutes merely a *portion* of a larger device—for instance, the interface between a flange and a water pump—it would be inappropriate to classify the entire water pump itself as a "flange-type part." Conversely, smaller components—such as valves—that feature such flanged interfaces may indeed be appropriately categorized as "flange-type parts." -:- For detailed product information, please contact sales. -: Niagara LaSalle 1117 Cold Finished Steel Flange Bar Product Information -:- For detailed product information, please contact sales. -: Niagara LaSalle 1117 Cold Finished Steel Flange Bar Synonyms -:- For detailed product information, please contact sales. -:

Niagara LaSalle 1117 Cold Finished Steel Bar Product Information -:- For detailed product information, please contact sales. -: # **Product Introduction: Niagara LaSalle 1117 Cold Finished Steel Bar** **Niagara LaSalle 1117** is a premium-grade **cold finished, low-carbon, resulfurized steel bar** engineered for applications demanding superior machinability while maintaining good strength and surface finish. This product represents Niagara LaSalle's high-quality production of the standard AISI/SAE 1117 alloy, processed through precision cold drawing to enhance its mechanical properties and dimensional characteristics beyond hot-rolled equivalents. As a resulfurized "free-machining" steel, 1117 is specifically formulated to provide exceptional chip formation and breakability during machining operations. Its controlled sulfur content, combined with the benefits of cold finishing, makes it an ideal choice for high-volume production of complex components where machining efficiency, tool life, and surface quality are paramount, while still offering better mechanical properties than standard free-cutting steels. --- ## **1. Chemical Composition (Per AISI/SAE 1117)** The composition adheres to the AISI/SAE 1117 specification with precise control over key elements to ensure optimal machinability and consistency. | Element | Carbon (C) | Manganese (Mn) | Phosphorus (P) | Sulfur (S) | | :--- | :--- | :--- | :--- | :--- | | **Content** | 0.14 - 0.20 | 1.00 - 1.30 | ≤ 0.040 | 0.08 - 0.13 | **Key Characteristics of the Composition:** * **Low Carbon with Resulfurization:** The combination provides excellent **machinability** while maintaining reasonable strength and ductility. Sulfur forms manganese sulfide (MnS) inclusions that act as internal chip breakers and lubricants during cutting. * **Elevated Manganese:** Higher than standard 1018/1020 grades, serving two critical functions: 1. **Balances Sulfur:** Ensures all sulfur is combined as benign MnS inclusions rather than brittle iron sulfides (FeS). 2. **Enhances Strength:** Contributes to higher as-supplied strength from cold working and improves response to case hardening. * **Free-Machining Grade:** Classified as a standard resulfurized grade, offering superior machinability compared to non-resulfurized low-carbon steels but with better transverse properties than highly rephosphorized grades like 12L14. --- ## **2. Physical & Mechanical Properties (Cold Drawn Condition)** Cold drawing significantly improves the properties of the base steel, resulting in a bar with excellent machining characteristics and enhanced mechanical performance. | Property | Typical Value - Cold Drawn | **Engineering Significance** | | :--- | :--- | :--- | | **Yield Strength (0.2% Offset)** | **70,000 - 85,000 psi (483 - 586 MPa)** | Good strength for a free-machining steel, suitable for many structural components. | | **Tensile Strength** | 80,000 - 95,000 psi (552 - 655 MPa) | | | **Elongation (in 2")** | **15%** (Minimum) | Maintains good ductility despite the sulfur content, better than leaded grades. | | **Reduction of Area** | 35% | | | **Hardness** | **149 - 179 HB** (80 - 88 HRB) | Provides moderate wear resistance and good machinability. | | **Machinability** | **~85% of 1212** | **Excellent machinability** with good chip control, allowing for higher production speeds, longer tool life, and superior surface finishes. | | **Surface Finish (As-Drawn)** | **32 - 63 µin Ra (0.8 - 1.6 µm)** | Clean, scale-free surface ideal for precision machining and plating. | | **Dimensional Tolerance** | Meets **ASTM A108** precision tolerances. | Excellent dimensional consistency for automated production. | | **Straightness** | Excellent | Critical for precision machining setups and long parts. | | **Case Hardenability** | Good | Readily responds to carburizing or carbonitriding for wear-resistant surfaces. | --- ## **3. Product Applications** Niagara LaSalle 1117 Cold Finished Bar is extensively used in high-volume manufacturing of components requiring extensive machining operations and good mechanical properties. * **Automotive Components:** **Bushings, spacers, fittings, small gears, and various fasteners** produced via screw machining. * **Hydraulic & Pneumatic Parts:** **Valve bodies, fittings, connectors, and pump components** requiring precise machining and sealing surfaces. * **General Machined Parts:** **Studs, bolts, nuts, pins, shafts, and sleeves** manufactured in high volumes on automatic screw machines or CNC lathes. * **Consumer Products & Hardware:** Components for appliances, power tools, furniture, and general hardware. * **Case-Hardened Components:** Ideal for parts that will undergo **carburizing or carbonitriding** to create wear-resistant surfaces while maintaining a tough core, such as certain gears and bearing races. --- ## **4. International & Equivalent Standards** AISI/SAE 1117 has direct and functional equivalents in major international standards systems. | Standard System | Equivalent Grade | **Notes & Key Distinctions** | | :--- | :--- | :--- | | **AISI / SAE** | **1117** (Cold Drawn) | The direct U.S. standard. | | **ASTM** | **A108** (Standard for Steel Bars, Carbon, Cold-Finished) | The governing U.S. standard for the cold-finished condition. | | **UNS** | G11170 | Unified Numbering System designation. | | **DIN (EN)** | **1.0721 (11SMn28)** | The closest European free-cutting steel. Note: European "SMn" grades typically have higher sulfur and may differ slightly in manganese range. | | **JIS** | **SUM22** | Japanese free-cutting steel with similar sulfur content and application. | | **GB (China)** | **Y15** | Chinese free-cutting steel grade. | | **ISO** | ISO 683-9: Type 1.0721 | International standard for free-cutting steels. | **Note on Equivalents:** While **1.0718 (11SMnPb30)** or **12L14** are sometimes mentioned, these are **leaded free-cutting steels** with significantly different composition and properties. 1117 is a **non-leaded, resulfurized grade**, offering a better balance of machinability, strength, and environmental considerations. --- ## **5. Key Advantages & Considerations** **Advantages:** * **Excellent Machinability:** One of the most machinable non-leaded steels, offering high production rates, extended tool life, and excellent surface finishes. * **Good Strength-to-Machinability Ratio:** Provides better mechanical properties than many free-cutting steels while maintaining superior machinability compared to non-resulfurized grades. * **Good Case Hardenability:** Responds well to surface hardening processes, making it versatile for wear applications. * **Superior Dimensional Consistency:** Cold finishing ensures tight tolerances and excellent straightness, reducing setup time and scrap rates. * **Non-Leaded Composition:** Environmentally preferable and avoids issues associated with leaded steels in certain applications or regions. **Considerations:** * **Anisotropic Properties:** Mechanical properties (especially ductility and impact toughness) are significantly lower in the transverse direction due to the elongated MnS inclusions. * **Limited Weldability:** **Not recommended for welding.** The sulfur content dramatically increases the risk of hot cracking (solidification cracking) in the weld and heat-affected zone. * **Corrosion Susceptibility:** Like all carbon steels, requires protective coatings for corrosion resistance. MnS inclusions can also act as initiation sites for corrosion. * **Not for High-Stress Applications:** The reduced transverse ductility makes it unsuitable for critically stressed components loaded perpendicular to the grain direction. --- **Disclaimer:** The properties listed are typical for cold-drawn 1117.
