1,We Manufacturing processes are primarily classified into four types: 1:Forging, 2:Casting, 3:Cutting, 4:Rolling. 2,We can manufacture in accordance with these standards. Standards: GB Series (Chinese Standards), JB Series (Machinery Standards), HG Series (Chemical Industry Standards), ASME B16.5 (American Standards), BS4504 (British Standards), DIN (German Standards), and JIS (Japanese Standards). Internationally, there are two primary systems of pipe flange standards: the European system, represented by the German DIN standards (including those of the former Soviet Union), and the American system, represented by the US ANSI pipe flange standards. 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. -: Latrobe HS-105™ ASTM M35 DIN 1.3243 High Speed Steel Flange Product Information -:- For detailed product information, please contact sales. -: Latrobe HS-105™ ASTM M35 DIN 1.3243 High Speed Steel Flange Synonyms -:- For detailed product information, please contact sales. -:

Latrobe HS-105™ ASTM M35 DIN 1.3243 High Speed Steel Product Information -:- For detailed product information, please contact sales. -: ### **Product Datasheet: Latrobe HS-105™ ASTM M35 / DIN 1.3243 Cobalt High-Speed Steel** --- #### **1. Product Overview** **Latrobe HS-105™** is a premium cobalt-enriched high-speed steel that meets both **ASTM A600 M35** and **DIN 1.3243** specifications. As a 5% cobalt modification of the classic M2 grade, HS-105™ is engineered to deliver significantly enhanced **red hardness (hot hardness)** and **wear resistance** at elevated temperatures. It is the ideal choice for demanding machining operations where cutting edges are subjected to high thermal loads, bridging the gap between standard high-speed steels and more expensive super-high-speed grades. --- #### **2. Key Features & Benefits** * **Superior Red Hardness:** The 5% cobalt addition dramatically improves the steel's ability to retain hardness and cutting-edge integrity at temperatures exceeding 600°C (1112°F), enabling higher cutting speeds and feeds. * **Excellent Wear Resistance:** A balanced carbide structure (from vanadium and tungsten) provides strong resistance to abrasive wear, extending tool life in difficult-to-machine materials. * **Good Toughness Balance:** Maintains better toughness than higher-cobalt grades (e.g., M42), making it suitable for applications with moderate interruptions or shock loads. * **Versatile Performance:** Consistently outperforms standard M2 in production environments where thermal buildup is a primary cause of tool failure. --- #### **3. Chemical Composition (Weight %)** HS-105™ conforms to the strict requirements for M35 / 1.3243 with a typical analysis as follows: | Element | ASTM M35 / DIN 1.3243 Range | Typical HS-105™ Analysis | | :--- | :--- | :--- | | **Carbon (C)** | 0.88 - 0.96 | 0.92 | | **Cobalt (Co)** | 4.50 - 5.50 | 5.00 | | **Tungsten (W)** | 5.90 - 6.70 | 6.30 | | **Molybdenum (Mo)**| 4.70 - 5.20 | 4.95 | | **Chromium (Cr)** | 3.70 - 4.20 | 3.95 | | **Vanadium (V)** | 1.70 - 2.10 | 1.90 | | **Manganese (Mn)** | 0.15 - 0.40 | 0.30 | | **Silicon (Si)** | 0.20 - 0.45 | 0.35 | | **Sulfur (S)** | ≤ 0.03 | 0.015 | | **Phosphorus (P)** | ≤ 0.03 | 0.020 | --- #### **4.

Heat Treatment Guidelines** **Annealing:** Heat to 850–880°C (1562–1616°F), slow cool (≤ 22°C/h) to 600°C. **Hardening:** * **Preheating:** 800–850°C (1472–1562°F) – crucial for complex shapes. * **Austenitizing:** 1210–1240°C (2210–2264°F) – precise control is essential. * **Quenching:** Oil, salt, or pressurized gas. * **Tempering:** **Triple tempering is mandatory.** Temper at 540–570°C (1004–1058°F) for 2+ hours each cycle. Hardness peaks after the second or third temper. --- #### **6. Primary Applications** HS-105™ (M35) is specified for tools that require greater hot hardness than M2 can provide: * **Cutting Tools for Hard/Abvasive Materials:** Drills, taps, end mills, and reamers for machining stainless steels, high-temperature alloys (e.g., Inconel), and hardened alloy steels. * **High-Speed Production Tools:** Gear hobs, broaches, and form tools where increased cutting speeds are needed to boost productivity. * **Precision Tools:** CNC tooling for milling and turning where consistent performance under thermal stress is critical. * **Cold Work Tools:** Punches and dies for forming high-strength materials where die wear is accelerated by frictional heat. --- #### **7.

Performance Comparison** * **vs. M2 (HS-6-5-2 / 1.3343):** HS-105™ offers significantly better hot hardness and wear resistance at high temperatures, allowing for 15-30% higher cutting speeds. * **vs. M42 (8% Co):** HS-105™ offers better toughness and grindability, while M42 achieves higher peak hardness and slightly better red hardness. * **General:** It is the **standard choice for cobalt HSS** when a reliable upgrade from M2 is needed without moving to the more sensitive and expensive ultra-high-cobalt grades. --- #### **9. Available Forms & Processing Notes** * **Forms:** Hot-rolled & forged bars, cold-drawn bars, precision ground stock. * **Machining:** Use carbide tooling in the annealed state. * **Grinding:** Use aluminum oxide or CBN wheels with ample coolant. Grindability is lower than M2 but better than M42. * **Coatings:** An excellent substrate for PVD coatings (TiN, TiAlN, AlCrN), which synergize with its hot hardness properties. --- #### **10.
