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. -: Sandvik 6C27 Strip Steel Flange Product Information -:- For detailed product information, please contact sales. -: Sandvik 6C27 Strip Steel Flange Synonyms -:- For detailed product information, please contact sales. -:

Sandvik 6C27 Strip Steel Product Information -:- For detailed product information, please contact sales. -: **Product Datasheet: Sandvik 6C27 Strip Steel** **1. Product Overview** Sandvik 6C27 is a versatile, low-alloy carbon strip steel developed for high-volume, precision cold-forming applications. It is engineered to deliver an optimal combination of consistent hardness, good ductility, and excellent dimensional accuracy. This material is the preferred choice for manufacturers requiring reliable performance in complex stamped, bent, or formed components, particularly in safety-critical industries like automotive. **2. Key Features & Benefits** * **Excellent Cold Formability:** Offers superior ductility in its supplied condition, allowing for complex and deep-drawing operations without cracking. * **Consistent & Uniform Hardness:** Guarantees predictable springback and forming behavior, leading to higher production yields and consistent part quality. * **Good Hardenability:** Responds effectively to heat treatment (carburizing or through-hardening), enabling the creation of a hard, wear-resistant surface with a tough core. * **High Purity & Cleanliness:** Controlled levels of impurities (S, P) and a fine, uniform microstructure ensure reliable performance and enhance fatigue life in final components. * **Precision Dimensional Tolerances:** Supplied with tight control on thickness, width, and flatness, suitable for automated, high-speed stamping lines. **3.

Processing & Heat Treatment Guidelines** 1. **Forming:** All stamping, bending, and deep-drawing operations should be completed in the supplied soft-annealed condition. 2. **Heat Treatment:** Parts are typically **carburized** (case-hardened) or **through-hardened** by quenching and tempering to achieve the final mechanical properties. The specific cycle (temperature, time, atmosphere) must be optimized for the part geometry. 3. **Machining:** Can be machined in the soft state; machining after hardening requires grinding or hard turning operations. 4. **Surface Finish:** Suitable for various surface treatments post-hardening, including phosphate coating, plating, or painting. **8.
