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 D5 UNS T90405 Tool Steel Flange Product Information -:- For detailed product information, please contact sales. -: MetalTek MTEK D5 UNS T90405 Tool Steel Flange Synonyms -:- For detailed product information, please contact sales. -:

Overview** **MetalTek MTEK D5 Cast Tool Steel** is a specialized **high-carbon, high-chromium, air-hardening cold work tool steel** manufactured through **advanced investment casting processes** to produce near-net-shape components requiring exceptional **wear resistance combined with moderate toughness**. Designated as **UNS T90405** (the cast equivalent of wrought AISI D5), this alloy represents a distinct variant within the high-carbon, high-chromium (HCHCr) family, characterized by its **significantly higher chromium content and moderate carbon** compared to D2. This composition creates an exceptionally high volume of chromium carbides while maintaining better dimensional stability during heat treatment. The casting process enables production of complex, large-scale wear components that would be prohibitively expensive to machine from solid stock, making it an ideal solution for severe abrasive applications in heavy industry. ## **2. International Standards & Specifications** This material is the cast product form of a specialized, high-chromium tool steel grade. * **Primary Standard Designations:** * **UNS T90405:** Unified Numbering System designation for **Cast D5 Tool Steel**. * **Wrought Reference Standard:** **AISI D5 / UNS T30405**. * **Governing Cast Standard:** **ASTM A597** Standard Specification for Cast Tool Steel. Specific foundry grades correspond to D5 composition. * **Key International Equivalents (Wrought Reference):** * **European:** No direct DIN equivalent; falls between **1.2601 (X165CrMoV12)** and **1.2379 (X153CrMoV12)** in composition. * **Japanese:** **JIS G4404 SKD1** is a close approximation. * **Common Industry Names:** **Cast D5**, **High-Chromium D5**, **Investment Cast D5 Tool Steel**. ## **3. Chemical Composition (Weight %, per ASTM A597 typical)** The composition is distinguished by very high chromium and controlled carbon to optimize carbide formation. | Element | Typical Range (%) | Role & Benefit in Cast D5 | |---------|------------------|----------------------------| | **Carbon (C)** | 1.40 – 1.60 | Similar to D2, but balanced with higher Cr to form massive chromium carbides without excessive matrix brittleness. | | **Chromium (Cr)** | 14.00 – 16.00 | **Exceptionally high.** Primary carbide former. Creates an extremely high volume of hard chromium carbides (Cr₇C₃) for supreme wear resistance. Also provides better corrosion/oxidation resistance than D2. | | **Molybdenum (Mo)** | 0.50 – 1.00 | Enhances hardenability and refines cast microstructure. Lower than D2 due to high Cr's hardenability contribution. | | **Vanadium (V)** | 0.15 – 0.50 | Added for grain refinement. Lower than D2 as primary wear resistance comes from Cr carbides. | | **Manganese (Mn)** | 0.20 – 0.60 | Aids in deoxidation and hardenability. | | **Silicon (Si)** | 0.10 – 0.60 | Deoxidizer and solid solution strengthener. | | **Foundry Practice:** Requires precise control of solidification to prevent excessive carbide network formation. Often utilizes **Hot Isostatic Pressing (HIP)** to ensure density and homogeneity. ## **4.
