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 100CrMnSi6-6 832K Steel Flange, Spheroidize annealing Product Information -:- For detailed product information, please contact sales. -: Ovako 100CrMnSi6-6 832K Steel Flange, Spheroidize annealing Synonyms -:- For detailed product information, please contact sales. -:

Distinguished by its elevated chromium and balanced silicon-manganese content, this alloy represents a distinct chemistry within Ovako's portfolio, positioned between standard 100Cr6 and higher-alloy tool steels. The **"832K"** designation indicates a **premium controlled-quality grade** ("K" often denoting a specially processed or high-integrity variant), characterized by enhanced homogeneity and consistent hardenability. The spheroidize annealed microstructure provides optimal machinability and prepares the material for achieving maximum hardness and wear performance after heat treatment. ## **Key Features & Benefits** * **Superior Wear and Abrasion Resistance:** The high chromium content (~1.5%) promotes the formation of a significant volume of hard, wear-resistant chromium carbides. After hardening, this results in **exceptional resistance to abrasive wear, galling, and rolling contact fatigue**, exceeding the performance of standard 100Cr6. * **High Hardness and Compressive Strength Potential:** With a carbon content of approximately 1%, this steel can achieve very high hardness (**61-65 HRC**) after proper heat treatment. This, combined with the alloy carbides, provides **outstanding compressive yield strength** and resistance to deformation under extreme contact pressures. * **Good Toughness Balance:** The balanced manganese and moderate silicon content contribute to good hardenability while helping to maintain **adequate toughness for a high-carbon, high-chromium steel**, reducing the risk of chipping or brittle fracture compared to more extreme alloy compositions. * **Controlled Quality for Predictable Performance:** The 832K grade ensures consistent chemical composition and a homogeneous spheroidized annealed structure. This leads to **predictable machining behavior, uniform response to heat treatment, and reliable final properties**. * **Excellent Machinability in Annealed State:** The spheroidize annealed condition provides a uniform hardness (~200 HB) and fine globular carbide structure, ensuring **good chip formation, extended tool life, and efficient machining** of complex geometries prior to hardening. ## **International Standards & Designations** This steel corresponds to a specific, high-chromium bearing steel grade. | Region/Standard | Standard Designation | Common Name / Equivalent | | :--- | :--- | :--- | | **EUR (EN)** | **~1.3528** (Approximate) | The likely standard designation.
