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 Crusader™ ASTM M3-2 High Speed Steel Flange Product Information -:- For detailed product information, please contact sales. -: Latrobe Crusader™ ASTM M3-2 High Speed Steel Flange Synonyms -:- For detailed product information, please contact sales. -:

Latrobe Crusader™ ASTM M3-2 High Speed Steel Product Information -:- For detailed product information, please contact sales. -: ### **Product Datasheet: Latrobe Crusader™ ASTM M3-2 High-Speed Steel (HSS)** **1. Product Overview** Latrobe Crusader™ is a premium, high-vanadium, high-carbon molybdenum-based high-speed steel conforming to the ASTM A600 M3 Class 2 specification. It is engineered as a superior alternative to standard M2 and M35 grades, offering an outstanding balance of **exceptional abrasion resistance** and **good toughness**. The "Crusader" name signifies its capability to handle the most demanding, abrasive machining applications where tool life is limited by wear rather than shock. **2. Key Features & Benefits** * **Superior Abrasion/Wear Resistance:** Contains a significantly higher vanadium content (approximately 3%) compared to M2, resulting in a greater volume of extremely hard vanadium carbides. This makes it ideal for machining abrasive materials. * **Excellent Hot Hardness:** Maintains cutting edge strength and hardness at the high temperatures generated during machining. * **Optimized Balance:** The M3-2 chemistry provides better toughness than the higher-carbon M3 Class 1, offering a more practical balance for a wider range of severe-duty applications. * **Consistent Quality:** Produced with Latrobe's rigorous melt and processing controls to ensure uniformity and predictable performance in heat treatment and application. **3. Standard Chemical Composition (Weight %)** Crusader™ is manufactured to the precise requirements of ASTM A600 M3 Class 2. The typical analysis is: | Element | Content (%) | Element | Content (%) | | :--- | :--- | :--- | :--- | | **Carbon (C)** | 1.15 - 1.25 | **Tungsten (W)** | 5.00 - 6.75 | | **Chromium (Cr)** | 3.75 - 4.50 | **Vanadium (V)** | 2.75 - 3.25 | | **Molybdenum (Mo)**| 4.75 - 6.50 | **Cobalt (Co)** | - | | **Manganese (Mn)** | 0.15 - 0.40 | **Sulfur (S)** | ≤ 0.03 | | **Silicon (Si)** | 0.20 - 0.45 | **Phosphorus (P)** | ≤ 0.03 | *(Note: The key distinction of M3-2 vs. M2 is the higher Carbon and Vanadium for wear resistance, and it contains no added Cobalt, distinguishing it from M36 or other cobalt-bearing grades.)* **4. Typical Physical & Mechanical Properties** * **Density:** ~8.16 g/cm³ (0.295 lb/in³) * **Thermal Conductivity:** Low, characteristic of complex high-alloy HSS. * **Coefficient of Thermal Expansion:** ~11.5 x 10⁻⁶ /K (20-400°C) * **Hardness (Annealed):** Maximum 255 HB * **Hardness (Hardened & Tempered):** **65 - 67 HRC** (Achievable with proper heat treatment. Typically run at the higher end of this range to maximize wear resistance). **5. Primary Applications** Crusader™ (M3-2) is specifically selected for applications where severe abrasive wear is the primary failure mode: * **Cutting Tools:** Form tools, gear hobs, broaches, milling cutters, and high-performance taps/drills for machining **abrasive materials** such as: * High-silicon aluminum alloys * Heat-treated alloy steels * Stainless steels * Composite materials * Plastics with abrasive fillers (e.g., fiberglass) * **Wear Parts:** Punches, dies, and forming tools subject to constant friction and wear. * **Industrial Knives:** Blades for cutting abrasive non-metallic materials like rubber, paper, and certain composites. **6. Relevant International Standards** Latrobe Crusader™ is produced to meet or exceed the following international standards: * **ASTM A600-92 (Reapproved):** Standard Specification for High-Speed Steel (M3 Class 2). * **UNS:** T11343 * **Equivalent Designations:** * **AISI:** M3 Class 2 * **DIN:** 1.3344 * **ISO:** HS6-5-3 * **JIS:** SKH53 **7. Comparison & Selection Guidance** * **vs. M2:** Crusader™ (M3-2) offers significantly better wear resistance but may have slightly lower toughness. Choose M3-2 for abrasive conditions. * **vs. M3 Class 1:** M3-2 has slightly lower carbon, providing better toughness while retaining excellent wear resistance, making it a more versatile choice. * **vs. Cobalt Grades (M35, M42):** Crusader™ lacks cobalt, so it has lower hot hardness but better toughness and is more cost-effective for applications not requiring extreme red hardness. **8.
