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 Lescowear™ Cold Work Tool Steel Flange Product Information -:- For detailed product information, please contact sales. -: Latrobe Lescowear™ Cold Work Tool Steel Flange Synonyms -:- For detailed product information, please contact sales. -:

Latrobe Lescowear™ Cold Work Tool Steel Product Information -:- For detailed product information, please contact sales. -: # **Latrobe Lescowear™ Cold Work Tool Steel** ## **Product Overview** Latrobe Lescowear™ is a proprietary, high-performance **shock-resistant cold work tool steel** engineered specifically to deliver exceptional toughness and wear resistance in demanding applications. Through advanced metallurgical design, Lescowear™ achieves a superior balance between **impact resistance, abrasive wear resistance, and dimensional stability**, making it a versatile choice for tools subject to high stress, intermittent loading, and abrasive conditions. It is particularly valued in applications where conventional tool steels are prone to chipping, cracking, or premature wear failure. ## **Key Features & Benefits** * **Superior Toughness:** Provides outstanding resistance to chipping, cracking, and fatigue failure under high-impact or intermittent loading conditions, significantly extending tool life in demanding operations. * **Excellent Wear Resistance:** Balanced alloy composition ensures robust resistance to abrasive wear, offering service life superior to standard shock-resistant grades (S-series) in wear-intensive applications. * **Good Dimensional Stability:** As an air-hardening grade, it exhibits minimal distortion during heat treatment, ensuring geometric accuracy and reducing post-processing requirements for precision tooling. * **Versatile Performance Profile:** Engineered to bridge the performance gap between high-toughness/low-wear steels (e.g., S7) and high-wear/moderate-toughness steels (e.g., D2), providing a reliable solution for complex failure modes. * **Consistent Microstructure:** Proprietary manufacturing processes ensure uniform carbide distribution and consistent mechanical properties throughout the material cross-section. ## **International Standard & Designations** * **Manufacturer's Proprietary Grade:** **Latrobe Lescowear™** * This is a proprietary steel chemistry not defined by standard AISI/ASTM nomenclature. * **Functional Classification:** High-toughness, air-hardening cold work tool steel with enhanced wear characteristics. * **Common International Equivalents (Functional):** * Comparable in performance philosophy to other proprietary high-toughness cold work steels, such as Uddeholm's **Sverker 21** or similar grades designed for combined impact and wear resistance. ## **Chemical Composition (%, typical - Proprietary)** The chemistry is optimized for a fine-grained, tough matrix with a controlled volume of wear-resistant carbides. | Carbon (C) | Chromium (Cr) | Molybdenum (Mo) | Vanadium (V) | Silicon (Si) | Manganese (Mn) | Other (Proprietary) | Iron (Fe) | | :--- | :--- | :--- | :--- | :--- | :--- | :--- | :--- | | 0.55 - 0.65 | 4.00 - 5.00 | 2.00 - 3.00 | 0.30 - 0.50 | 0.20 - 0.40 | 0.20 - 0.50 | Balance* | Balance | **\*Note:** The exact proprietary composition may include carefully controlled levels of elements such as nickel (Ni) to further enhance core toughness.
