Other common standards include: the Chinese Ministry of Machinery Industry standards (JB series), the Ministry of Chemical Industry standards (HG series), the Chinese National Standard *GB/T 9112–9124-2010 Steel Pipe Flanges*, as well as US standards (ASME B16.5), British standards (BS4504), German standards (DIN), Japanese standards (JIS), and marine standards (CBM), among others. The nominal pressure ratings for the PN series are designated by "PN" and comprise the following nine levels: PN2.5, PN6, PN10, PN16, PN25, PN40, PN63, PN100, and PN160. The nominal pressure ratings for the Class series are designated by "Class" and comprise the following six levels: Class150, Class300, Class600, Class900, Class1500, and Class2500.

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. -: MetalTek MTEK H13 UNS T90813 Tool Steel Flange Product Information -:- For detailed product information, please contact sales. -: MetalTek MTEK H13 UNS T90813 Tool Steel Flange Synonyms -:- For detailed product information, please contact sales. -:

MetalTek MTEK H13 UNS T90813 Tool Steel Product Information -:- For detailed product information, please contact sales. -: # **Product Introduction: MetalTek MTEK H13 Cast Tool Steel (UNS T90813)** ## **1. Overview** **MetalTek MTEK H13 Cast Tool Steel** is a premium **chromium-molybdenum-vanadium hot work tool steel** manufactured through **specialized investment casting processes** to produce large, complex near-net-shape components for demanding high-temperature applications. Designated as **UNS T90813** (the cast equivalent of wrought AISI H13, UNS T20813), this material delivers the essential combination of **high-temperature strength, thermal fatigue resistance, and toughness** that defines H13's performance, but in cast form optimized for complex geometries. The casting process enables production of monolithic die components with integrated cooling channels, intricate contours, and large-scale dimensions that would be impossible or prohibitively expensive to machine from solid blocks, making it an ideal solution for advanced die casting, hot forging, and plastic injection molding tooling. ## **2.

It transforms hot work tooling from a compromise between machinability and performance into an optimized system where thermal management is engineered directly into the die material. For applications where cooling efficiency dictates productivity—such as large aluminum die castings or complex plastic molds—cast H13 with conformal cooling provides a quantum leap in performance. It enables not just longer die life through traditional H13 properties, but fundamentally faster cycle times and better part quality through intelligent thermal design. This makes it not merely an alternative to wrought H13, but a superior solution for the most demanding, high-value tooling applications where performance and total cost of ownership are paramount. -:- For detailed product information, please contact sales. -: MetalTek MTEK H13 UNS T90813 Tool Steel Specification Dimensions Size： Diameter 20-1000 mm Length <7069 mm Size:We can customized as required Standard： Per your request or drawing We can customized as required Properties（Theoretical） Chemical Composition -:- For detailed product information, please contact sales. -: MetalTek MTEK H13 UNS T90813 Tool Steel Properties -:- For detailed product information, please contact sales. -:
