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. -: AISI E50100 Steel Flange Product Information -:- For detailed product information, please contact sales. -: AISI E50100 Steel Flange Synonyms -:- For detailed product information, please contact sales. -:

Physical & Mechanical Properties (Typical - After Full Hardening & Tempering)** *Note: Properties are dependent on section size and specific heat treatment (austenitizing temperature, quench medium, tempering temperature).* * **Hardness (Hardened & Tempered):** **60 – 66 HRC** (typical tempering range: 150°C – 250°C). * **Tensile Strength:** ~ 2000 – 2400 MPa (very high, but brittleness is a concern at full hardness). * **Yield Strength (0.2% Offset):** ~ 1500 – 1900 MPa. * **Elongation at Break:** Low (< 5% at full hardness), improves slightly with higher tempering temperatures. * **Reduction of Area:** Low. * **Fatigue Strength (Rotating Bending):** High, a key property for bearing applications. * **Physical Constants:** * **Density:** 7.83 g/cm³ * **Modulus of Elasticity:** ~ 210 GPa * **Thermal Conductivity:** ~ 46 W/m·K (at 100°C) * **Coefficient of Thermal Expansion:** ~ 11.5 x 10⁻⁶/K (20-100°C) **5. Heat Treatment Characteristics** * **Forging:** Heat uniformly to 1050°C – 1100°C (1920°F – 2010°F). Do not forge below 850°C (1560°F). Must be annealed after forging. * **Annealing (Spheroidize Annealing):** Required for machinability. Heat to 780°C – 810°C (1435°F – 1490°F), slow cool. Resulting hardness: ~ 179 – 229 HB. * **Hardening:** Austenitize at **820°C – 860°C** (1510°F – 1580°F), followed by **oil quenching**. Can also be martempered (hot oil quench) to reduce distortion. * **Tempering:** **Mandatory immediately after quenching.** Typical range is **150°C – 250°C** to relieve quenching stresses, improve toughness marginally, and stabilize microstructure without significant loss of hardness. * **Dimensional Stability:** For critical applications (e.g., gauges), sub-zero treatment and multiple tempering cycles may be used to transform retained austenite. **6. Primary Applications** AISI E50100 is the workhorse steel for a vast range of high-wear, high-contact stress components: * **Bearings:** **Ball bearings**, **roller bearings**, bearing races, and slewing rings. * **Automotive:** Constant velocity joint components, needle roller bearings, fuel pump shafts, high-wear pins. * **Industrial Machinery:** Gears, shafts, rollers, liners, balls for ball screws, machine tool spindles, and wear plates. * **Other:** High-quality blades, cutting tools (knives, slitters), and precision measuring instruments. **7. Key Advantages & Selection Rationale** * **High Hardness & Wear Resistance:** The ~1% carbon content ensures a high volume of hard carbides. * **Excellent Fatigue Life:** Clean steelmaking (E-grade) and fine carbide distribution provide superior rolling contact fatigue resistance. * **Good Hardenability:** The chromium content allows through-hardening of moderate sections in oil. * **Wide Industry Acceptance:** A globally recognized standard material with well-established processing guidelines and abundant supply chain support. --- **Disclaimer:** This data sheet provides typical information based on standard specifications.
