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. -: Ovako C45 047A Steel Flange, Hot forging Product Information -:- For detailed product information, please contact sales. -: Ovako C45 047A Steel Flange, Hot forging Synonyms -:- For detailed product information, please contact sales. -:

Ovako C45 047A Steel, Hot forging Product Information -:- For detailed product information, please contact sales. -: # **Product Introduction: Ovako C45 047A Steel, Hot Forging Quality** **Ovako C45 047A** is a high-quality **medium-carbon steel grade specifically designed and optimized for hot forging applications**. This product designation indicates a steel supplied in a form suitable for hot deformation processes, with a chemical composition and microstructure tailored to ensure excellent forgeability, consistent response to heat treatment after forging, and reliable final mechanical properties. The "047A" specification reflects Ovako's internal classification for forging-quality steels, implying controlled chemical ranges, good hardenability, and a predictable behavior during the forging and subsequent cooling cycles. It is a fundamental material for producing high-strength, durable components through hot forging, offering a balance of performance and process efficiency. --- ## **1. Chemical Composition (Ovako 047A Specification)** The chemistry is based on a controlled C45 composition, optimized for forging and subsequent heat treatment. | Element | Carbon (C) | Silicon (Si) | Manganese (Mn) | Phosphorus (P) | Sulfur (S) | Chromium (Cr) | **Forging Optimization** | | :--- | :--- | :--- | :--- | :--- | :--- | :--- | :--- | | **Range** | 0.42 - 0.50 | 0.15 - 0.40 | 0.60 - 0.90 | **≤ 0.030** | **≤ 0.030** | ≤ 0.30 | **Balanced for hot workability & hardenability** | | **Key Role** | Base strength | Deoxidizer | Hardenability control | **Controlled for forgeability & toughness** | **Controlled for isotropy** | Enhances hardenability & uniformity | | **Critical Features of the Composition for Forging:** * **Forging-Friendly Carbon Range:** The 0.45% nominal carbon provides a good combination of hot plasticity and final achievable strength after heat treatment. * **Controlled Manganese & Chromium:** These elements provide adequate hardenability to ensure the forged part can be through-hardened after forging, even in moderate cross-sections. * **Sulfur & Phosphorus Control:** Maintained at moderate, controlled levels (**≤0.030%**). Sulfur is not elevated for machinability as in free-cutting steels, as this would be detrimental to hot ductility and transverse properties in forged components. * **Predictable Behavior:** The tight compositional control ensures consistent flow stress during forging, uniform grain structure development, and predictable hardenability post-forging. --- ## **2. Physical & Mechanical Properties** Properties are defined for the **as-supplied (typically as-rolled or annealed) forging stock** and for the **final forged and heat-treated component**. **A. Supplied Condition (Forging Stock - e.g., Hot-rolled):** * **Microstructure:** Uniform ferrite-pearlite to facilitate uniform deformation. * **Hardness:** ~160 - 200 HB. Soft enough for good forgeability. * **Purpose:** Optimized for hot workability, not for final mechanical performance. **B. After Hot Forging & Controlled Cooling:** * **Microstructure:** Refined, deformed grain structure from thermomechanical processing. * **Properties:** Vary with cooling rate. Air cooling may yield properties similar to normalized steel (~550-700 MPa Rm). Faster cooling may lead to higher hardness. **C. After Hot Forging, Quenching & Tempering (Typical Final State):** * **Tensile Strength (Rm):** **850 - 1200 MPa** (Depending on tempering temperature) * **Yield Strength (Rp0.2):** **650 - 1000 MPa** * **Hardness:** **25 - 40 HRC** (Typical for structural components) * **Impact Toughness:** Good, benefiting from the forged, refined grain structure. * **Fatigue Strength:** Enhanced by the forged fiber grain flow, which follows the component contour. --- ## **3. Product Applications** Ovako C45 047A is the material of choice for a wide range of **hot-forged, high-strength components** across various heavy industries. * **Automotive & Truck:** **Crankshafts, connecting rods, steering knuckles, axle beams, and gear blanks.** * **Agricultural & Construction Machinery:** **Gears, pinions, lever arms, bucket teeth adapters, and high-strength pins.** * **General Engineering:** **Flanges, forged shafts, valve bodies, and heavy-duty couplings.** * **Hand Tools:** **Forged wrenches, sockets, and pry bars.** * **Oil & Gas:** **Forged fittings, valve components, and small drill string parts.** --- ## **4. International & Equivalent Standards** This forging-quality steel corresponds to standard forging grades in international systems. | Standard System | Equivalent / Comparable Grade | **Relationship / Note** | | :--- | :--- | :--- | | **Ovako Specification** | **C45 047A (Hot Forging)** | The exact product specification for forging. | | **EN 10250-3 (Open Die)** / **EN 10250-4 (Forgings)** | **1.0503 (C45)** | The standard European grade for forgings. | | **ASTM A668** | **Class F (1045)** | The standard ASTM specification for carbon steel forgings. This is a very close equivalent. | | **DIN 17200 (Withdrawn)** | **Ck 45 (for forgings)** | Historical German standard for forging steel. | | **JIS G3201** | **SF 540 / SF 490** | Japanese carbon steel forgings. SF540 has a similar minimum tensile strength. | | **GB/T 699** | **45# Steel (Forging Quality)** | Chinese forging grade equivalent. | **Key Distinction:** While the base chemistry aligns with C45/1045, the **"047A" designation and its association with "Hot Forging"** indicate that Ovako has optimized the steel's internal quality (deoxidation, grain size control) and consistency specifically for the hot forging process, ensuring reliable performance in demanding forging applications. --- ## **5. Key Advantages & Considerations** **Advantages:** * **Excellent Hot Forgeability:** Predictable flow behavior and good hot ductility reduce forging defects and die wear. * **Good Hardenability Post-Forging:** Allows for effective through-hardening of forged parts to achieve high strength. * **Enhanced Mechanical Properties:** The forged grain flow provides inherent directional strength and improved fatigue resistance compared to machined-from-bar components. * **Material Efficiency:** Forging allows for near-net-shape production, minimizing material waste. * **Consistent Quality:** Ovako's controlled production ensures batch-to-batch consistency critical for automated forging lines. **Considerations:** * **Requires Secondary Processing:** The supplied stock is not a final product; it requires customer hot forging and almost always subsequent heat treatment and machining. * **Decarburization:** Hot forging and subsequent heat treatment can cause surface decarburization, which may need to be machined off for critical surfaces. * **Forging Process Control:** Final properties are highly dependent on the customer's forging temperatures, deformation rates, and cooling controls. * **Not for Cold Forging:** Designed for hot working; its ductility at room temperature is insufficient for severe cold forging operations. --- **Disclaimer:** The final properties of a component made from Ovako C45 047A are a result of the complex interaction between the base material and the customer's specific **forging parameters (temperature, strain, strain rate), cooling cycle, and final heat treatment**. For critical applications, it is essential to conduct forging and heat treatment trials and to collaborate with Ovako's technical service to optimize the process for the desired outcome.
