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 1213 Cold Finished Steel Flange Bar Product Information -:- For detailed product information, please contact sales. -: Niagara LaSalle 1213 Cold Finished Steel Flange Bar Synonyms -:- For detailed product information, please contact sales. -:

Niagara LaSalle 1213 Cold Finished Steel Bar Product Information -:- For detailed product information, please contact sales. -: # **Product Introduction: Niagara LaSalle 1213 Cold Finished Steel Bar** **Niagara LaSalle 1213** is a premium-grade **cold finished, low-carbon, free-machining steel bar** engineered for specialized applications where superior surface finish and chip-breaking characteristics are paramount during machining operations. As a variation of the standard free-machining steel family, AISI/SAE 1213 features a higher sulfur content than 1212, resulting in even more effective chip control and better machined surface quality, albeit with a slight trade-off in cold forming characteristics and mechanical strength. This material is produced under Niagara LaSalle's stringent quality controls, ensuring consistent chemical composition, superior dimensional accuracy, and excellent surface condition. The cold drawing process enhances its straightness and provides a clean, scale-free surface ideal for high-speed, precision machining of components where aesthetic appearance and minimal post-machining finishing are required. --- ## **1. Chemical Composition (Per AISI/SAE 1213)** The composition is specifically balanced to maximize machining performance through optimized sulfur content. | Element | Carbon (C) | Manganese (Mn) | Phosphorus (P) | Sulfur (S) | | :--- | :--- | :--- | :--- | :--- | | **Content** | 0.13 max | 0.70 - 1.00 | 0.07 - 0.12 | **0.24 - 0.33** | | *Key Difference vs. 1212* | Same | Same | Same | **Higher: 0.24-0.33 vs. 0.16-0.23** | **Key Characteristics of the Composition:** * **Ultra-High Sulfur Content:** The defining feature of 1213. The elevated sulfur level (0.24-0.33%) creates a higher volume of **manganese sulfide (MnS) inclusions**. These inclusions: 1. **Act as superior chip breakers**, producing shorter, more manageable chips than 1212. 2. **Provide internal lubrication** during cutting, reducing friction and heat generation. 3. **Contribute to a superior machined surface finish** by promoting a smoother cutting action. * **Rephosphorized:** The phosphorus content remains high (0.07-0.12%), further increasing chip brittleness. * **Free-Machining Focus:** This chemistry is singularly optimized for **machinability and surface finish**, with mechanical properties being a secondary consideration. --- ## **2. Physical & Mechanical Properties (Cold Drawn Condition)** The properties of 1213 reflect its design purpose as a high-performance machining steel. | Property | Typical Value - Cold Drawn | **Engineering Significance** | | :--- | :--- | :--- | | **Yield Strength (0.2% Offset)** | **55,000 - 65,000 psi (379 - 448 MPa)** | Moderate strength, adequate for light-duty, non-structural components. Slightly lower than 1212 due to higher inclusion content. | | **Tensile Strength** | 65,000 - 75,000 psi (448 - 517 MPa) | | | **Elongation (in 2")** | **10%** (Minimum) | Very low ductility, characteristic of high-sulfur free-machining steels. | | **Hardness** | **121 - 170 HB** (68 - 85 HRB) | Soft structure optimized for minimal tool wear. | | **Machinability** | **~110-120% of 1212** | **Exceptional machinability and surface finish.** Often rated higher than 1212 for ease of machining and quality of finish, though tool wear may be slightly increased due to abrasive MnS inclusions. | | **Surface Finish (As-Drawn)** | **32 - 63 µin Ra (0.8 - 1.6 µm)** | Excellent starting condition for precision work. | | **Machined Surface Finish** | **Can achieve very fine finishes (e.g., < 32 µin Ra)** | One of its key benefits, often reducing or eliminating the need for secondary finishing operations. | | **Dimensional Tolerance** | Meets **ASTM A108** precision tolerances. | Critical for consistent high-volume production. | | **Chip Characteristics** | **Very short, powdery chips** | Excellent chip control, ideal for automated environments. | --- ## **3. Product Applications** Niagara LaSalle 1213 Cold Finished Bar is specified for components where **exceptional machined surface quality, fine tolerances, and trouble-free chip disposal are critical**, and where mechanical loads are minimal. * **High-Precision Screw Machine Parts:** **Electrical connectors, precision fittings, small shafts, and nozzles** requiring mirror-like finishes. * **Hydraulic & Pneumatic Fittings:** **Ferrule nuts, compression fittings, and valve stems** where smooth surfaces are essential for sealing. * **Electrical & Electronic Hardware:** **Terminals, contact pins, and shielding components** where surface quality affects electrical performance or plating adhesion. * **Consumer Product Components:** **Knobs, decorative trim pieces, and fasteners** for appliances and electronics where appearance is important. * **Plumbing Fixtures:** **Precision parts for faucets and valves** requiring good machined finishes. --- ## **4. International & Equivalent Standards** AISI 1213 is a specific North American grade. Its higher sulfur content makes finding direct chemical equivalents less common than for 1212. | Standard System | Equivalent / Comparable Grade | **Notes & Key Distinctions** | | :--- | :--- | :--- | | **AISI / SAE** | **1213** (Cold Drawn) | The direct U.S. standard, defined by its high sulfur range. | | **ASTM** | **A108** | Governing standard for the cold-finished condition. | | **UNS** | G12130 | Unified Numbering System. | | **DIN (EN)** | **1.0715 (9SMn28)** or **1.0737 (11SMn30)** | The closest European free-cutting steels. Sulfur levels are typically lower than 1213. A direct match is uncommon. | | **ISO** | ISO 683-9: Types 1.0715/1.0737 | International standards for free-cutting steels. | | **JIS** | **SUM22** or **SUM22L** | Japanese free-cutting steels. SUM22L has added lead. The sulfur content is generally lower than 1213. | | **GB (China)** | **Y15** | Chinese free-cutting steel. May not reach the sulfur level of 1213. | | **Proprietary** | **La-Led® (12L14)** | For applications prioritizing machinability over ultimate surface finish, 12L14 is an alternative, though it contains lead. | **Key Distinction:** **1213 is the non-leaded free-machining steel of choice when the absolute best machined surface finish is required.** While 12L14 may machine slightly faster, 1213 often produces a superior final surface on the part. --- ## **5. Key Advantages & Considerations** **Advantages:** * **Superior Machined Surface Finish:** Often produces the best surface quality among standard non-leaded free-machining steels. * **Excellent Chip Control:** The high sulfur content creates very short, easily disposed chips, ideal for high-volume automated machining. * **Good Machinability:** Allows for high cutting speeds and reduced cycle times. * **Non-Leaded Composition:** Avoids environmental and regulatory concerns associated with leaded steels. * **Consistent Quality:** Niagara LaSalle's production ensures uniform material behavior batch-to-batch. **Considerations:** * **Very Low Mechanical Properties:** The weakest of the common free-machining steels (1212, 12L14, 1213). **Not for any structural application.** * **Extremely Poor Weldability:** **Completely unweldable.** The very high sulfur and phosphorus guarantee severe hot cracking. * **Brittle with No Ductility:** Virtually no capacity for cold bending or forming. Parts must be machined to final shape. * **High Corrosion Susceptibility:** Requires protective coatings. The high density of MnS inclusions can accelerate corrosion. * **Anisotropic Properties Extreme:** Severe directionality; parts will split easily under transverse load. --- **Disclaimer:** The properties listed are typical for cold-drawn 1213.
