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. -: Carpenter Micro-Melt® 9 Tough Treated Tool Steel Flange Product Information -:- For detailed product information, please contact sales. -: Carpenter Micro-Melt® 9 Tough Treated Tool Steel Flange Synonyms -:- For detailed product information, please contact sales. -:

Carpenter Micro-Melt® 9 Tough Treated Tool Steel Product Information -:- For detailed product information, please contact sales. -: ### **Carpenter Micro-Melt® 9 Tough Treated Tool Steel: Premium High Toughness Tool Steel** **Product Overview** Carpenter Micro-Melt® 9 Tough Treated (often abbreviated as CPM 9T or simply 9TT) is an air-hardening, tungsten-molybdenum high-carbon, high-chromium tool steel produced via the advanced powder metallurgy (PM) process. This proprietary manufacturing method, known as Micro-Melt®, results in a material with a fine, uniform, and isotropic microstructure. The primary design objective of Micro-Melt 9 is to deliver **exceptional toughness and impact resistance** while maintaining good wear resistance and high compressive strength, making it an ideal choice for demanding tooling applications subjected to severe stress. **Key Advantages** * **Superior Toughness:** Offers significantly higher toughness than conventional D2 or similar high-chromium tool steels, reducing the risk of chipping and catastrophic failure. * **Excellent Wear Resistance:** Provides good abrasion resistance suitable for many forming and cutting applications. * **High Compressive Strength:** Withstands high loads without deforming. * **Good Dimensional Stability:** Minimal distortion during heat treatment due to its air-hardening nature. * **Uniform Microstructure:** The PM process ensures consistent performance in all directions, free from the carbide segregation found in ingot-cast steels. * **Improved Machinability & Grindability:** Compared to conventional steels of similar alloy content, the fine carbides enhance machinability in the annealed state and improve grindability in the hardened state. **Typical Chemical Composition (%)** The precise composition is proprietary to Carpenter Technology, but it falls within the following range, aligning with AISI Type A8 tool steel modifications: | Element | Carbon (C) | Chromium (Cr) | Molybdenum (Mo) | Tungsten (W) | Vanadium (V) | Silicon (Si) | Manganese (Mn) | | :--- | :---: | :---: | :---: | :---: | :---: | :---: | :---: | | **Content** | 0.50 - 0.60 | 4.75 - 5.25 | 1.30 - 1.80 | 1.30 - 1.80 | 0.90 - 1.10 | 0.15 - 0.40 | 0.20 - 0.50 | **Physical & Mechanical Properties** * **Density:** 7.87 g/cm³ (0.284 lb/in³) * **Thermal Conductivity:** Relatively low, typical of high-alloy tool steels. * **Coefficient of Thermal Expansion:** ~ 10.8 x 10⁻⁶/°C (20-100°C) * **Hardness (Hardened & Tempered):** Typically used in the range of **58-62 HRC**. The optimal balance of toughness and wear resistance is often achieved at **59-61 HRC**. * **Toughness:** Notably higher than conventional D2 and similar to or better than S7 shock steel at equivalent hardness levels, which is its standout feature. * **Compressive Strength:** Very high, typically > 3,000 MPa (435 ksi) at 60 HRC. **Heat Treatment** * **Annealing:** Furnace cool to 480°C (900°F) at 15°C (25°F) per hour, then air cool. Typical annealed hardness: 200-230 HB. * **Stress Relieving:** 650-675°C (1200-1250°F), then air cool. * **Preheating:** Two-stage preheat is critical: First at 540-650°C (1000-1200°F), then at 815-870°C (1500-1600°F). * **Austenitizing:** 1010-1065°C (1850-1950°F). Soak time depends on section size. * **Quenching:** Air cool or positive pressure air quench. For complex shapes, interrupted quenching in a salt bath at 540-595°C (1000-1100°F) followed by air cooling is recommended. * **Tempering:** **Mandatory.** Double or triple temper immediately after quenching. Temperature range: 540-595°C (1000-1100°F) for 2+ hours per cycle. Hardness will stabilize in the 58-62 HRC range. **International Standards & Cross-References** * **Carpenter Proprietary:** Micro-Melt 9 Tough Treated (CPM 9T). * **UNS:** T30109 * **AISI:** Modified Type A8 (PM version). * **European (EN):** Similar to but outperforms 1.2606 (55NiCrMoV7) in toughness. * **Japanese (JIS):** No direct equivalent; positioned between SKD11 and SKD61 in terms of toughness/wear balance. **Typical Applications** Micro-Melt 9 is specifically chosen for applications where **toughness is the primary concern** but more wear resistance than traditional shock steels (like S7) is required. 1. **Forming & Punching Dies:** * Heavy-duty punching and blanking dies (especially for high-strength materials). * Forming rolls, slitter rings, and wear plates. * Cold forging dies and headers (for non-extreme wear applications). * Thread rolling dies. 2. **Shearing & Cutting Tools:** * Industrial knives for cutting difficult materials (cables, composites, plastics). * Shear blades for metal processing. 3. **Molds & Tooling:** * Injection molds with high shear points or cores prone to breakage. * Dies for casting aluminum and zinc under high pressure. 4. **Other Critical Tools:** * Arbors, mandrels, and master tools. * Chisels and tools for demolition or mining where impact is key. * Machinery components requiring high strength and fatigue resistance. **Conclusion** Carpenter Micro-Melt® 9 Tough Treated Tool Steel represents a significant advancement in tool steel performance, bridging the gap between high-wear and high-toughness grades.
