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. -: InduSteel Flange TENASteel Flange® Cold Work Tool Steel Flange Product Information -:- For detailed product information, please contact sales. -: InduSteel Flange TENASteel Flange® Cold Work Tool Steel Flange Synonyms -:- For detailed product information, please contact sales. -:

Industeel TENASTEEL® Cold Work Tool Steel Product Information -:- For detailed product information, please contact sales. -: # **Industeel TENASTEEL® Cold Work Tool Steel** ## **Product Overview** Industeel TENASTEEL® represents a premium range of cold work tool steels specifically engineered for applications requiring exceptional wear resistance, high compressive strength, and dimensional stability under load. These steels are characterized by their advanced metallurgical purity, homogeneous microstructure, and optimized heat treatment response. TENASTEEL® grades are produced through state-of-the-art secondary refining processes (such as Electro-Slag Remelting - ESR or Vacuum Arc Remelting - VAR) to ensure minimal segregation, uniform carbide distribution, and superior isotropy of properties. This results in tools with longer service life, consistent performance, and reduced risk of premature failure in demanding cold forming operations. ## **Key Features & Benefits** * **Superior Microstructural Purity:** Advanced melting technologies (ESR/VAR) drastically reduce non-metallic inclusions and eliminate macro-segregation. This enhances polishability, etching quality, and fatigue resistance. * **Excellent Wear Resistance:** High carbon and carbide-forming alloy content (Cr, Mo, V) leads to the formation of hard, fine carbides that provide outstanding resistance to abrasive wear, galling, and adhesive wear. * **High Compressive Strength & Hardness:** Capable of achieving very high hardness levels (up to 64+ HRC), enabling tools to withstand extreme pressures without deformation or indentation. * **Good Toughness:** Balanced chemistry and clean steelmaking provide relatively good toughness for their hardness class, reducing susceptibility to chipping and cracking. * **Superior Dimensional Stability:** Low distortion during heat treatment due to high hardenability and homogeneous structure, critical for precision tools. * **Enhanced Grindability & Machinability (Annealed State):** Supplied in a spheroidized annealed condition for safe and efficient machining of complex tool geometries. ## **Product Range & International Standards** The TENASTEEL® family includes several classic cold work steel grades, each with specific characteristics.
