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. Flange Classification 1. **According to Chemical Industry Standards:** Flanges are classified as follows: Plate Flat Welding Flange (PL), Necked Flat Welding Flange (SO), Necked Butt Welding Flange (WN), Integral Flange (IF), Socket Welding Flange (SW), Threaded Flange (Th), Butt Welding Ring Loose Flange (PJ/SE), Blind Flange (BL), Flat Welding Ring Loose Flange (PJ/PJ), and Lined Blind Flange (BL(s)). 2. **According to Petrochemical (SH) Industry Standards:** Flanges are classified as follows: Threaded Flange (PL), Butt Welding Flange (WN), Flat Welding Flange (SO), Socket Welding Flange (SW), Loose Flange (LJ), and Blind Flange (no specific designation). 3. **According to Machinery (JB) Industry Standards:** Flanges are classified as follows: Integral Flange, Butt Welding Flange, Plate Flat Welding Flange, Butt Welding Ring Plate Loose Flange, Flat Welding Ring Plate Loose Flange, Lap Joint Ring Plate Loose Flange, and Blind Flange. 4. **According to Connection Method/Type:** Flanges are classified as follows: Plate Flat Welding Flange, Necked Flat Welding Flange, Necked Butt Welding Flange, Socket Welding Flange, Threaded Flange, Blind Flange, Necked Butt Welding Ring Loose Flange, Flat Welding Ring Loose Flange, Ring-Type Joint (RTJ) Flange and Blind Flange, Large-Diameter Plate Flange, Large-Diameter High-Neck Flange, Figure-8 Blind Plate, Butt Welding Ring Loose Flange, etc. 5. **According to the Component Being Connected:** Flanges can be classified into Vessel Flanges and Pipe Flanges. 6. **According to Structural Type:** Flanges include Integral Flanges, Threaded Flanges, Flat Welding Flanges, Butt Welding Flanges, Lap Joint (Loose/Swivel) Flanges, and Blind Flanges. 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 CM-50™ ASTM M50 High Speed Steel Flange Product Information -:- For detailed product information, please contact sales. -: Latrobe CM-50™ ASTM M50 High Speed Steel Flange Synonyms -:- For detailed product information, please contact sales. -:

Latrobe CM-50™ ASTM M50 High Speed Steel Product Information -:- For detailed product information, please contact sales. -: **Latrobe CM-50™ ASTM M50 High Speed Steel** **Product Overview** Latrobe CM-50™ is a premium molybdenum-tungsten high-speed steel alloy produced to the ASTM A600 standard for M50 grade. Engineered for exceptional **rolling contact fatigue (RCF) resistance**, **high-temperature hardness**, and **toughness**, CM-50™ represents a critical material solution for demanding aerospace and industrial applications. Unlike traditional tungsten-rich high-speed steels, CM-50™ utilizes a balanced molybdenum-tungsten-vanadium composition, offering a superior combination of hot hardness and resistance to spalling in high-stress environments. This makes it the preferred choice for components subjected to extreme mechanical and thermal stresses, particularly in modern high-performance turbine engines. **Key Features & Benefits** * **Superior Rolling Contact Fatigue (RCF) Life:** Excellent resistance to subsurface fatigue failure, making it ideal for bearings operating under high loads and stresses. * **Optimized Hot Hardness:** Maintains high hardness at elevated temperatures (up to ~540°C / 1000°F), ensuring dimensional stability and wear resistance in hot sections. * **Enhanced Toughness:** Offers better toughness and resistance to shock and chipping compared to many higher-carbon, higher-vanadium HSS grades. * **Consistent Performance:** Latrobe's advanced melting and processing ensure a clean, homogeneous microstructure with minimal segregation, leading to predictable and reliable performance. **International Standard & Designations** * **Primary Standard:** **ASTM A600-92a (R2023):** Standard Specification for Tool Steel High Speed. * **Grade:** **M50** * **Aerospace Material Specification:** **AMS 6491E** (Instrument Quality M50) * **Unified Numbering System (UNS):** **T11350** * **Common International Equivalents:** * **ISO:** **HS 2-9-2-8** (Closest equivalent) * **Germany (DIN/W-Nr.):** **1.3547 / S 10-4-3-10** (Similar composition) * **France (AFNOR):** **Z 130 WDCV 09-04-04-02** **Chemical Composition (%, typical)** The balanced alloy design of CM-50™ provides its unique property profile. | Carbon (C) | Molybdenum (Mo) | Tungsten (W) | Vanadium (V) | Chromium (Cr) | Cobalt (Co) | Iron (Fe) | | :--- | :--- | :--- | :--- | :--- | :--- | :--- | | 0.78 - 0.88 | 3.75 - 4.50 | 3.75 - 4.50 | 0.90 - 1.10 | 3.75 - 4.50 | ≤ 1.00 (Note 1) | Balance | | **Note 1:** Standard M50 typically contains ≤ 1.0% Co.
