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 A2 Cast UNS T90102 Tool Steel Flange Product Information -:- For detailed product information, please contact sales. -: MetalTek MTEK A2 Cast UNS T90102 Tool Steel Flange Synonyms -:- For detailed product information, please contact sales. -:

Overview** **MetalTek MTEK A2 Cast Tool Steel** is a premium **air-hardening, chromium-molybdenum-vanadium cold work tool steel** manufactured via **specialized investment casting processes** to produce near-net-shape components with complex geometries. Designated under the Unified Numbering System as **UNS T90102** (the cast equivalent of wrought AISI A2, UNS T30102), this material delivers the essential properties of standard A2 tool steel—**good wear resistance, high toughness, and excellent dimensional stability during heat treatment**—in cast form. By utilizing investment casting, MetalTek enables the production of large, intricate, or customized tooling components that would be prohibitively expensive or impossible to machine from solid bar stock, while maintaining consistent metallurgical quality and performance. ## **2.

Controlled to balance hardness with castability. | | **Chromium (Cr)** | 4.75 – 5.50 | Provides hardenability, wear resistance, and moderate corrosion resistance. | | **Molybdenum (Mo)** | 0.90 – 1.40 | Enhances hardenability, toughness, and refines grain structure in the cast state. | | **Vanadium (V)** | 0.15 – 0.50 | Forms hard vanadium carbides for wear resistance and acts as a potent grain refiner, critical for controlling the as-cast microstructure. | | **Manganese (Mn)** | 0.40 – 1.00 | Aids in deoxidation and hardenability. | | **Silicon (Si)** | 0.10 – 0.60 | Deoxidizer and solid solution strengthener. | | **Additional Foundry Practice:** May include grain refiners and strict melting controls (e.g., Argon-Oxygen Decarburization) to ensure cleanliness and homogeneity. ## **4. Typical Physical & Mechanical Properties (Heat Treated)** * **As-Cast Condition:** Supplied annealed for machinability. Microstructure is fully transformed via heat treatment to match wrought properties. * **Recommended Heat Treatment:** Similar to wrought A2 but may require specific soak times due to cast microstructure. * **Preheating:** 650-700°C (1200-1290°F) * **Austenitizing:** 940-980°C (1725-1795°F) * **Quenching:** **Air cool** (standard, minimal distortion). * **Tempering:** **Double tempering** at 175-540°C (350-1000°F) based on desired hardness/toughness balance. * **Mechanical Properties (Hardened & Double Tempered):** * **Hardness:** **58 – 62 HRC** (achievable, comparable to wrought A2). * **Tensile Strength:** 1850 – 2050 MPa (268,000 – 297,000 psi) * **Yield Strength (0.2% Offset):** High. * **Impact Toughness (Charpy):** **Good.** Slightly more isotropic than wrought due to equiaxed cast grains, though overall levels are comparable when properly processed. * **Wear Resistance:** **Very Good,** suitable for blanking, forming, and cutting applications. * **Key Advantages of Cast Form:** * **Geometry Complexity:** Can produce internal passages, contours, and integrated features in one piece. * **Material & Machining Savings:** Significant reduction in buy-to-fly ratio and rough machining hours. * **Rapid Prototyping:** Faster production of complex tooling prototypes. * **Large Component Capability:** Can cast very large sections unsuitable for forged billets. ## **5. Product Application** MTEK A2 Cast Tool Steel is ideal for **large, complex, or customized tooling components** where near-net-shape manufacturing offers economic or geometric advantages. * **Large Forming & Stamping Dies:** * **Automotive body panel dies,** especially with complex curvatures. * **Large bending and forming dies** for aerospace or heavy industry. * **Specialized Cutting & Shearing Tools:** * **Custom industrial knife bodies** with complex profiles or internal features. * **Large shear blade holders and assemblies.** * **Wear Parts & Machine Components:** * **Rolls, guides, and wear plates** with intricate cooling channels or mounting features. * **Anvil blocks and tool holders** for forging and pressing. * **Plastic & Rubber Molds:** * **Large mold bases or cavity blocks** with conformal cooling channels cast directly into the tool. ## **6. Key Features & Advantages** * **Complex Geometry Enablement:** The primary benefit. Creates monolithic tools with internal features impossible to machine. * **Cost-Effectiveness for Complex Shapes:** Dramatically reduces material waste and machining time for intricate components. * **Consistent Metallurgical Properties:** Advanced foundry techniques ensure uniform composition and microstructure throughout the casting. * **Good Machinability in Annealed State:** Can be finish-machined similarly to wrought A2 after casting. * **Isotropic Structure:** The as-cast grain structure can be more uniform in all directions than the directional grain flow of wrought material, potentially offering more consistent properties. * **Scalability:** Can produce components from a few pounds to several tons. ## **7. Processing & Quality Considerations** * **Pattern & Mold Design:** Critical first step. Requires expertise to account for shrinkage, gating, and riser design to ensure soundness. * **Heat Treatment is Mandatory:** As-cast properties are not suitable for service. Must undergo full AQT cycle. * **Non-Destructive Testing (NDT):** Essential for critical components. Typically includes **radiographic (X-ray) inspection** to check for internal porosity or shrinkage, and **liquid penetrant inspection** for surface defects. * **Finish Machining:** All critical surfaces and dimensions require final machining after heat treatment to achieve required tolerances and finishes. * **Potential for Casting Defects:** Risk of micro-porosity or inclusions exists and must be managed through rigorous process control and inspection. **Summary:** MetalTek MTEK A2 Cast Tool Steel (UNS T90102) redefines the manufacturing paradigm for complex tooling by applying investment casting technology to a trusted cold work steel alloy.
