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. -: JIS SKH10 Tungsten High Speed Tool Steel Flange Product Information -:- For detailed product information, please contact sales. -: JIS SKH10 Tungsten High Speed Tool Steel Flange Synonyms -:- For detailed product information, please contact sales. -:

JIS SKH10 Tungsten High Speed Tool Steel Product Information -:- For detailed product information, please contact sales. -: **Product Name:** JIS SKH10 Tungsten High-Speed Tool Steel **International Standard:** JIS G4403 (Japan Industrial Standard) - High-Speed Tool Steels --- ### **1. Overview** JIS SKH10 is a **high-tungsten, high-carbon, cobalt-free high-speed steel** belonging to the tungsten (T-series) category. It is characterized by its exceptional **red hardness, superior abrasion resistance, and high compressive strength**. Primarily designed for cutting tools operating at high speeds and under severe conditions, it maintains its cutting edge at elevated temperatures generated during machining. Its high tungsten content makes it particularly suitable for machining tough and abrasive materials, though it is less shock-resistant than molybdenum-type high-speed steels. --- ### **2. Chemical Composition (Typical Weight %)** | Element | Content (%) | |---------|-------------| | C | 0.70–0.85 | | Si | 0.20–0.45 | | Mn | 0.15–0.40 | | Cr | 3.50–4.50 | | W | 17.0–19.0 | | V | 1.00–1.50 | | Co | ≤ 1.00 | | P (max) | 0.030 | | S (max) | 0.030 | *Balance: Iron (Fe).* *Note: SKH10 contains negligible cobalt, making it a cost-effective alternative to cobalt-bearing grades for many applications.* --- ### **3. Physical & Mechanical Properties** - **Density:** ~8.25 g/cm³ - **Thermal Conductivity:** ~24 W/m·K (at 20°C) - **Coefficient of Thermal Expansion:** ~11.5 ×10⁻⁶ /K (20–500°C) - **Hardness (Annealed):** ~277 HB (max) - **Hardness (Hardened & Tempered):** 63–66 HRC (typical) - **Tempering Temperature Range:** 540–600°C (Triple tempering recommended) - **Maximum Service Temperature:** ~600°C (maintains hardness effectively) - **Key Features:** Excellent wear resistance, high hot hardness, but lower toughness compared to some Mo-based HSS. --- ### **4. Heat Treatment** - **Annealing:** Heat to 800–880°C, slow cool (10–20°C/h) to 600°C, then air cool. Annealed hardness should be ≤277 HB. - **Hardening (Quenching):** - **Preheat:** 800–850°C (to prevent thermal shock) - **Austenitizing:** **1260–1310°C** (Careful temperature control is critical to avoid grain growth and overheating). Soak time should be as short as possible. - **Quenching:** Oil, air, or salt bath quench. - **Tempering:** **Double or triple temper at 540–600°C** for 1–2 hours each, cooling to room temperature between tempers. Peak hardness is typically achieved after tempering at 550–570°C. --- ### **5. Key Features & Advantages** - **Exceptional Red Hardness:** Retains hardness at high cutting temperatures due to high tungsten and vanadium content. - **Superior Abrasion Resistance:** High vanadium and tungsten carbides provide excellent resistance to wear from abrasive materials. - **Good Compressive Strength:** Suitable for tools under high pressure. - **Cost-Effective for Tungsten HSS:** Offers a balance of performance without the high cost of cobalt addition. - **Limitation:** Lower toughness and higher sensitivity to thermal shock compared to M-series (Mo-based) high-speed steels. --- ### **6. Typical Applications** SKH10 is widely used for manufacturing cutting tools that require high wear resistance and hot hardness: - **Cutting Tools:** Drills, taps, reamers, end mills, broaches, and milling cutters for machining **cast iron, carbon steel, alloy steel, and non-ferrous metals**. - **Forming Tools:** Gear hobs, shaping tools, and thread rolling dies. - **Heavy-Duty Tools:** Tools for machining abrasive materials like fiber-reinforced plastics, hard rubber, and certain high-temperature alloys. - **Woodworking Tools:** High-performance blades and cutter heads for hardwoods and composite boards. - **Punches and Dies:** For cold-work applications requiring high wear resistance. --- ### **7. Equivalent Steel Grades (International Standards)** - **ISO:** HS18-0-1 - **DIN (Germany):** 1.3355 / S18-0-1 - **AISI/SAE (USA):** T1 (Very similar, but T1 typically has ~0.75% V) - **GB (China):** W18Cr4V (A very close equivalent) - **UNS:** T12001 --- ### **8. Machining & Fabrication Notes** - **Machining:** Should be machined in the annealed condition. It is more difficult to machine than standard tool steels due to its high hardness and alloy content. Use carbide tools and lower speeds/feeds. - **Grinding:** Use proper grinding wheels (aluminum oxide or CBN) with ample coolant to avoid overheating and grinding cracks. Low-stress grinding practices are recommended. - **Welding:** Not generally recommended for tool fabrication due to high crack sensitivity. If necessary, requires specialized procedures, including high preheat (400-500°C) and post-weld slow cooling/annealing. - **Surface Treatment:** Can be effectively **nitrided (gas or plasma)** or coated (TiN, TiAlN, etc.) to further enhance surface hardness, wear resistance, and tool life. --- ### **9. Summary** JIS SKH10 is a classic tungsten-based high-speed steel that represents the foundational "T-series" HSS technology. It offers a proven combination of **very high wear resistance and excellent hot hardness**, making it a reliable and cost-effective choice for a wide range of cutting tools, particularly for applications involving abrasive materials and continuous cutting operations. While its toughness is lower than that of modern powder metallurgy or molybdenum-cobalt grades, its performance and established heat treatment practices ensure its continued use in general-purpose and demanding machining environments. Compliance with JIS G4403 guarantees consistent material quality for tool manufacturers worldwide. -:- For detailed product information, please contact sales. -: JIS SKH10 Tungsten High Speed Tool Steel Specification Dimensions Size： Diameter 20-1000 mm Length <6807 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. -: JIS SKH10 Tungsten High Speed Tool Steel Properties -:- For detailed product information, please contact sales. -:
