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. -: Assab Steel Flanges ASP 23 Cold Work Steel Flange Product Information -:- For detailed product information, please contact sales. -: Assab Steel Flanges ASP 23 Cold Work Steel Flange Synonyms -:- For detailed product information, please contact sales. -:

Assab Steels ASP 23 Cold Work Steel Product Information -:- For detailed product information, please contact sales. -: ### **Assab Steels ASP 23: High-Performance Powder Metallurgy High-Speed Steel for Cold Work** **Introduction** Assab Steels ASP 23 is a premium-grade, cobalt-free, high-vanadium tool steel manufactured using the advanced **Powder Metallurgy (PM)** process. Belonging to the ASP (AbraSiFion Particle) series, it is classified as a "semi-high-speed steel" and is engineered to deliver an exceptional balance of very high wear resistance, good toughness, and excellent compressive strength. This combination makes ASP 23 a superior choice for demanding cold work applications where conventional tool steels like D2 or even other PM grades cannot provide sufficient service life. **Key Value Propositions:** * **Superior Wear Resistance:** The PM process creates a uniform distribution of very hard, small vanadium carbides, resulting in outstanding resistance to abrasive wear. * **Excellent Toughness:** Offers significantly better toughness than conventional high-carbon, high-chromium steels of similar hardness, reducing the risk of chipping and cracking. * **High Compressive Strength:** Essential for forming, stamping, and powder compaction under high pressure. * **Good Grindability & Machinability:** For a high-vanadium steel, ASP 23 exhibits relatively good grindability in the hardened state due to its fine, homogeneous PM microstructure. * **Dimensional Stability:** Excellent stability during heat treatment with minimal distortion, a hallmark of PM steels. **International Standard Designations** * **Assab / Uddeholm:** ASP 23 * **AISI / ASTM:** Not a direct standard equivalent. It is a proprietary PM grade. * **European Norm (EN):** ~1.3395 (This is a PM steel designation, not a common standard). * **DIN:** Equivalent to matrix composition of high-speed steel, but PM. * **ISO:** HS7-4-2-5 (PM) [Closest equivalent based on composition]. * **Common Comparisons:** Often positioned between conventional D2 (1.2379) and ultra-high-wear PM grades like VANADIS 10. Similar PM grades from other manufacturers include **Böhler S390** and **Crucible CPM M4**. **Chemical Composition (Typical Weight %)** | Element | Carbon (C) | Tungsten (W) | Molybdenum (Mo) | Chromium (Cr) | Vanadium (V) | Cobalt (Co) | | :--- | :---: | :---: | :---: | :---: | :---: | :---: | | **%** | 1.28 | 6.4 | 5.0 | 4.2 | 3.1 | - | *Note: The high Tungsten and Molybdenum content provides hot hardness and strength, while the high Vanadium content ensures exceptional wear resistance through the formation of VC carbides.* **Physical & Mechanical Properties (Typical, Hardened Condition)** * **Density:** ~8.10 g/cm³ * **Thermal Conductivity:** ~25 W/m·K (at 20°C) * **Coefficient of Thermal Expansion:** ~11.0 x 10⁻⁶/K (20-200°C) * **Elastic Modulus:** ~215 GPa * **Hardness (after heat treatment):** 60-64 HRC (Typically used at 60-62 HRC for optimal balance). * **Compressive Strength:** ~ 3200 MPa (at 62 HRC). **Heat Treatment** * **Soft Annealed Hardness:** Approx. 280-320 HB. * **Austenitizing / Hardening Temperature:** **1120 - 1180°C** (Requires precise control, typically in vacuum or salt bath). * **Tempering Temperature:** **540 - 580°C.** Requires **double or triple tempering** (recommended: 3x 2 hours). The steel develops its peak secondary hardness in this range. A typical regimen is 560°C, three times. * **Hardenability:** Excellent through-hardening due to its PM nature. **Product Applications** ASP 23 is ideal for highly demanding cold work applications where wear is the primary failure mechanism, but some shock resistance is also required. * **Fine Blanking & Stamping:** Punches, dies, and ejectors for abrasive materials like high-strength steels, electrical laminations (silicon steel), and pre-coated metals. * **Cold Forming & Extrusion:** Forming rolls, extrusion dies, and punches for advanced high-strength steels (AHSS) and stainless steels. * **Thread Rolling & Knurling:** Dies for producing threads on hard or abrasive materials. * **Powder Compaction:** Critical parts like punches, cores, and die inserts in powder metal and ceramic compaction tools. * **Cutting Tools for Abrasive Materials:** Blades and knives for cutting composites, fiberglass, reinforced plastics, and hard papers. * **Long-Run Progressive Dies:** For wear-critical stations. **Available Forms** * Decarb-free, soft annealed. * Round bars and flat bars * Precision ground flat stock * Forged blocks and blanks * Custom-finished tool components **Comparison & Positioning** * **vs. CARMO (AISI D2):** ASP 23 offers dramatically higher wear resistance and compressive strength, with better toughness at high hardness. It is the logical upgrade when D2 fails due to wear. * **vs. VANADIS 10:** ASP 23 has lower vanadium content, making it slightly less wear-resistant but generally tougher and easier to grind. It is often chosen when the ultimate wear resistance of VANADIS 10 is not required, but a better toughness balance is needed. **Conclusion** Assab Steels ASP 23 represents a cornerstone of high-performance powder metallurgy tool steels. It fills the critical gap between conventional alloy steels and the ultra-high-wear PM grades, providing an optimal solution for the most challenging cold work applications. Its proven track record in extending tool life, improving productivity, and reducing downtime in severe conditions makes it a benchmark material for advanced tooling design. -:- For detailed product information, please contact sales. -: Assab Steels ASP 23 Cold Work Steel Specification Dimensions Size： Diameter 20-1000 mm Length <7239 mm Size:We can customized as required Standard： Per your request or drawing We can customized as required Properties（Theoretical） Chemical Composition -:- For detailed product information, please contact sales. -: Assab Steels ASP 23 Cold Work Steel Properties -:- For detailed product information, please contact sales. -:
