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 1045 Cold Finished Steel Flange Bar Product Information -:- For detailed product information, please contact sales. -: Niagara LaSalle 1045 Cold Finished Steel Flange Bar Synonyms -:- For detailed product information, please contact sales. -:

Niagara LaSalle 1045 Cold Finished Steel Bar Product Information -:- For detailed product information, please contact sales. -: # **Product Introduction: Niagara LaSalle 1045 Cold Finished Steel Bar** **Niagara LaSalle 1045** is a high-quality **cold finished, medium-carbon steel bar** produced under the stringent standards of Niagara LaSalle Corporation. It represents a premium-grade version of the standard AISI/SAE 1045 alloy, processed through precision cold drawing to deliver significantly enhanced mechanical properties, superior surface integrity, and exact dimensional tolerances compared to its hot-rolled counterpart. As a versatile medium-carbon steel, 1045 provides an excellent balance of strength, hardness, and moderate toughness. Niagara LaSalle's cold finishing process imparts a uniform, hardened surface layer and improves overall strength through strain hardening, making this material a preferred choice for parts requiring high wear resistance, good fatigue strength, and reliable machinability in a ready-to-use form or as a substrate for further heat treatment. --- ## **1. Chemical Composition (Per AISI/SAE 1045)** The composition strictly adheres to the AISI/SAE 1045 specification, with Niagara LaSalle ensuring tight control for metallurgical consistency. | Element | Carbon (C) | Manganese (Mn) | Phosphorus (P) | Sulfur (S) | | :--- | :--- | :--- | :--- | :--- | | **Content** | 0.43 - 0.50 | 0.60 - 0.90 | ≤ 0.040 | ≤ 0.050 | **Key Characteristics of the Composition:** * **Medium Carbon Content:** Provides the fundamental capacity for **through-hardening via heat treatment (quenching & tempering)**. In the cold-drawn condition, it forms the basis for higher as-supplied strength. * **Moderate Manganese:** Enhances hardenability, allowing for deeper and more effective hardening during heat treatment and contributing to the strength gained from cold working. * **Standard Quality:** Contains typical residual levels of phosphorus and sulfur. It is **not a free-machining variant**; for optimized machinability in similar strength ranges, leaded or re-sulfurized grades (e.g., 1144) are alternatives. --- ## **2. Physical & Mechanical Properties (Cold Drawn Condition)** Cold drawing transforms the hot-rolled microstructure, significantly elevating key mechanical properties. The values below are typical for Niagara LaSalle cold-drawn 1045 bars. | Property | Typical Value - Cold Drawn | **Engineering Significance** | | :--- | :--- | :--- | | **Yield Strength (0.2% Offset)** | **85,000 - 100,000 psi (586 - 690 MPa)** | **High yield strength** in the as-supplied state, suitable for many structural applications without further processing. | | **Tensile Strength** | 100,000 - 115,000 psi (690 - 793 MPa) | | | **Elongation (in 2")** | **10%** (Minimum) | Maintains reasonable ductility for forming and to absorb impact. | | **Reduction of Area** | 40% | | | **Hardness** | **170 - 207 HB** (87 - 95 HRB / ~HRC 17-22) | Provides **good inherent wear resistance** directly from the mill. | | **Machinability** | **~60% of 1212** | Fair machinability; requires appropriate tool geometry, feeds, and speeds. Excellent surface finish is achievable. | | **Surface Finish** | **32 - 63 µin Ra (0.8 - 1.6 µm)** | Superior, scale-free surface ideal for bearing surfaces, seals, or plating. | | **Dimensional Tolerance** | Meets **ASTM A108** precision tolerances. | Excellent for precision machining, reducing material removal and setup time. | | **Straightness** | Excellent | Essential for shafting and components requiring minimal runout. | **Properties After Heat Treatment (Quenched & Tempered):** * When through-hardened, 1045 can achieve: * **Tensile Strength:** 150,000 - 180,000 psi (1034 - 1241 MPa) * **Hardness:** **HRC 45 - 55** (depending on section size and tempering temperature) * **Notable:** Due to its moderate hardenability, full hardening is typically effective only in smaller cross-sections (e.g., under ~1 inch diameter for water quenching, larger for oil quenching). --- ## **3. Product Applications** Niagara LaSalle 1045 Cold Finished Bar is a fundamental engineering material used across industries for components that require higher strength and wear resistance than low-carbon steels can provide. * **General High-Strength Components:** **Shafts, spindles, gears, bolts, studs, and axles** subjected to moderate stresses and wear. * **Automotive & Agricultural:** **Crankshafts, steering components, hydraulic cylinder rods, and drive pins.** * **Machinery & Equipment:** **Lead screws, guide rods, rollers, and couplings.** * **Tooling & Fixtures:** **Jigs, fixtures, dies, and machine tool parts** where hardness and stability are required. * **Heat-Treated Parts:** An excellent and cost-effective choice for components that will be **induction hardened, flame hardened, or through-hardened** to achieve very high surface or core hardness. --- ## **4. International & Equivalent Standards** AISI/SAE 1045 is a globally recognized grade with direct equivalents in major standards systems. | Standard System | Equivalent Grade | **Notes on Condition** | | :--- | :--- | :--- | | **AISI / SAE** | **1045** (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** | G10450 | Unified Numbering System designation. | | **DIN (EN)** | **1.0503 (C45E / C45R)** | The most common European equivalent. "C45E" denotes engineering quality. | | **JIS** | **S45C** | The direct Japanese equivalent (nominal 0.45% C). | | **GB (China)** | **45# Steel** | Common Chinese designation. | | **ISO** | ISO 683-18: Type 1.0503 | International standard equivalent. | **Crucial Note:** Specifying **"Niagara LaSalle 1045"** or **"1045 Cold Finished per ASTM A108"** ensures procurement of material with the superior surface finish, dimensional accuracy, and enhanced as-supplied mechanical properties of a premium cold-drawn bar, distinguishing it from generic hot-rolled merchant stock. --- ## **5. Key Advantages & Considerations** **Advantages:** * **High "As-Supplied" Strength & Hardness:** The cold-drawn condition provides ready-to-use properties that often eliminate the need for heat treatment in many applications. * **Excellent Wear Resistance:** The harder surface offers better resistance to abrasion and galling than low-carbon steels. * **Good Response to Heat Treatment:** Can be easily through-hardened or surface hardened (induction/flame) to achieve very high strength and wear resistance for demanding applications. * **Superior Dimensional Control:** Tight tolerances and excellent straightness reduce machining time and improve part accuracy. **Considerations:** * **Moderate Machinability:** Less machinable than free-cutting or low-carbon steels; requires more power and careful tool selection. * **Limited Weldability:** Welding is possible but requires strict procedures (pre-heat, low-hydrogen electrodes, post-heat) due to the higher carbon content, which increases the risk of cracking in the heat-affected zone (HAZ). * **Hardenability Limit:** As a plain carbon steel, its hardenability is limited. For through-hardening of larger sections or for higher core strength, alloy steels like 4140 or 4340 are more appropriate. * **Corrosion Susceptibility:** Requires protective coatings for use in corrosive environments. --- **Disclaimer:** The properties listed are typical for cold-drawn 1045. Final part performance can be significantly influenced by machining practices, heat treatment parameters, and section size.
