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. -: Crucible Steel Flange CPM® S60V® Tool Steel Flange Product Information -:- For detailed product information, please contact sales. -: Crucible Steel Flange CPM® S60V® Tool Steel Flange Synonyms -:- For detailed product information, please contact sales. -:

Crucible Steel CPM® S60V® Tool Steel Product Information -:- For detailed product information, please contact sales. -: # **Product Introduction: Crucible CPM® S60V® Tool Steel** Crucible CPM® S60V® is a high-carbon, high-chromium, high-vanadium martensitic stainless tool steel manufactured via the Crucible Particle Metallurgy (CPM) process. Positioned as a high-performance wear-resistant stainless steel, it is engineered to offer **exceptional abrasion resistance combined with good corrosion resistance**, bridging the gap between standard stainless steels and ultra-high-wear non-stainless tool steels. As part of the CPM S-series stainless family, S60V provides a balanced approach with a significant volume of hard vanadium carbides embedded within a corrosion-resistant chromium-rich matrix. The CPM process is critical for this alloy, enabling a uniform distribution of fine vanadium carbides that would otherwise be coarse and segregated in conventional casting. This results in a material with **improved toughness, superior grindability, and excellent dimensional stability** compared to what could be achieved through ingot metallurgy. CPM S60V is designed for applications where components must endure severe sliding wear or abrasion in environments that preclude the use of non-stainless tool steels due to corrosion concerns. --- ## **1. Chemical Composition (Weight %)** The chemistry is defined by high carbon and chromium, with substantial vanadium for wear resistance. | **Element** | **Carbon (C)** | **Chromium (Cr)** | **Vanadium (V)** | **Molybdenum (Mo)** | **Silicon (Si)** | **Manganese (Mn)** | | :--- | :--- | :--- | :--- | :--- | :--- | :--- | | **Content** | 2.15 | 17.50 | 5.50 | 0.40 | 0.40 | 0.50 | | **Role** | Essential for forming hard carbides with vanadium and chromium, providing the base for high hardness and wear resistance. | Primary source of **stainless (corrosion-resistant) properties** via the passive chromium oxide layer. Also contributes to hardenability and forms chromium carbides. | **Primary wear resistance element.** Forms a high volume of extremely hard vanadium carbides (VC), which are the key to its outstanding abrasion resistance. | Enhances hardenability and improves toughness and tempering resistance. | Deoxidizer and solid solution strengthener. | Aids in deoxidation and improves hardenability. | *Note: Iron (Fe) constitutes the remainder. Nickel (Ni) and Copper (Cu) are typically minimal.* --- ## **2. Physical & Mechanical Properties** *Typical properties after proper heat treatment to a working hardness of 56-59 HRC.* * **Density:** ~7.67 g/cm³ (0.277 lb/in³) * **Modulus of Elasticity:** ~200 GPa (29 x 10⁶ psi) * **Thermal Conductivity:** Low, due to the high alloy and carbide content. * **Coefficient of Thermal Expansion:** ~10.8 x 10⁻⁶/°C (20-100°C) * **Corrosion Resistance:** **Good.** Superior to non-stainless tool steels (like D2 or M2) and offers good resistance in many atmospheric, fresh water, and mild chemical environments. Comparable to or better than 440C in many scenarios due to its high chromium content (~17.5%). * **Hardness (Typical Working Range):** **55 - 60 HRC.** Most commonly used at **57-59 HRC** for an optimal balance of wear resistance, toughness, and corrosion resistance. * **Abrasion Resistance:** **Excellent.** The high vanadium (5.5%) and carbon content create a substantial volume of ultra-hard vanadium carbides, providing wear resistance that far exceeds standard stainless steels (e.g., 440C, 154CM) and approaches that of dedicated high-wear PM tool steels like CPM 10V. * **Toughness:** **Moderate.** Its toughness is lower than less alloyed stainless steels like 440C or AEB-L, but the CPM process provides significantly better toughness than a conventionally processed version of this alloy. It is suitable for wear applications without severe impact. * **Grindability (Hardened):** **Difficult.** The high volume of hard vanadium carbides makes grinding challenging. **Diamond or CBN (Cubic Boron Nitride) abrasives are required** for efficient sharpening and finishing. --- ## **3. Heat Treatment** Precise heat treatment is required to optimize corrosion resistance and mechanical properties. * **Annealing:** Heat to 900-925°C (1650-1700°F), slow cool. Annealed hardness: 250-280 HB. * **Preheating:** **Essential.** Use a double preheat: First at 540-650°C (1000-1200°F), then at 815-870°C (1500-1600°F). * **Austenitizing:** 1080-1135°C (1975-2075°F). A common range is **1105-1120°C (2025-2050°F)**. Higher temperatures increase hardness and wear resistance but can reduce corrosion resistance and toughness. * **Quenching:** Air quench or positive pressure gas quench. **Do not oil quench,** to avoid compromising corrosion resistance and surface finish. * **Tempering:** **Mandatory.** Temper immediately after quenching. **Minimum of two tempers**, each for 2+ hours, are standard. * **Typical tempering range: 205-540°C (400-1000°F).** * For maximum corrosion resistance, temper at **205-425°C (400-800°F)**. Avoid the 425-565°C (800-1050°F) range to prevent chromium carbide precipitation and associated loss of corrosion resistance ("sensitization"). * For higher toughness and stability (with some sacrifice in corrosion resistance), temper at **540-565°C (1005-1050°F)**. * **Sub-Zero Treatment:** Recommended after quenching and before tempering to transform retained austenite, improving dimensional stability and maximizing hardness. --- ## **4. Key Applications** CPM S60V is ideal for components that suffer from severe wear in corrosive or hygienic environments. * **Food & Pharmaceutical Processing:** Wear plates, mixer blades, cutter heads, and pump components handling abrasive foodstuffs or powders where corrosion and contamination must be avoided. * **Chemical & Marine Equipment:** Valves, seals, bearings, and shafts exposed to abrasive slurries and corrosive media. * **Cutlery & Industrial Blades:** High-end knives, surgical instruments, and slitter blades requiring extreme edge retention and stain resistance for cutting fibrous or abrasive materials. * **Plastics & Extrusion:** Screws, barrels, and dies for processing highly filled or reinforced plastics (e.g., glass fiber, minerals) where corrosion from additives is a concern. * **General Wear Parts in Corrosive Atmospheres:** Guide rails, nozzles, and wear inserts where standard tool steels would corrode. --- ## **5. International Standards & Cross-References** CPM S60V is a proprietary grade within Crucible's CPM stainless steel family. * **UNS:** No standard UNS designation. * **AISI/SAE:** No direct equivalent. It is a proprietary martensitic stainless tool steel. * **European (EN):** No direct equivalent. Conceptually similar to high-vanadium stainless tool steels. * **ISO:** No direct equivalent. * **Common Trade Names/Equivalents:** The closest competitor analogues are other high-vanadium, high-chromium PM stainless steels, such as **Böhler M390** or similar "super clean" high-wear stainless grades. It is distinct from, but often compared to, **CPM S30V** (lower vanadium) and **CPM S90V** (higher vanadium and carbon). --- ## **6. Advantages & Limitations** **Advantages:** * **Outstanding Wear & Corrosion Balance:** Offers one of the best available combinations in a martensitic stainless steel. * **Superior Wear Resistance to Standard Stainless Steels:** Dramatically outperforms 440C, 154CM, and similar grades in abrasive environments. * **CPM Microstructure Benefits:** Provides better toughness and grindability than attainable with conventional processing of this alloy. * **High Hardness Attainability:** Can achieve a high hardness (57-59+ HRC) while maintaining good corrosion resistance. **Limitations:** * **Lower Toughness:** Not suitable for high-impact applications. More brittle than 440C or similar lower-alloy stainless steels. * **Difficult Machining & Grinding:** Requires carbide tooling and diamond/CBN abrasives, increasing manufacturing costs. * **Complex Heat Treatment:** Tempering temperature must be carefully chosen based on the priority of corrosion resistance versus toughness. * **Higher Cost:** Due to high alloy content (especially vanadium and chromium) and PM processing. --- ## **7. Summary** **Crucible CPM S60V is a specialized, high-performance stainless tool steel engineered to solve demanding wear problems in corrosive environments.** It fills a critical niche where the exceptional wear resistance of tool steels like CPM 10V is needed, but the application mandates the corrosion resistance of a stainless steel. For industries such as food processing, chemical handling, and marine technology, where component failure from a combination of abrasion and corrosion is a primary concern, S60V provides a durable, long-lasting solution that maintains integrity in challenging conditions. Its performance makes it a premium choice for applications where material failure is not an option. -:- For detailed product information, please contact sales. -: Crucible Steel CPM® S60V® Tool Steel Specification Dimensions Size： Diameter 20-1000 mm Length <6968 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. -: Crucible Steel CPM® S60V® Tool Steel Properties -:- For detailed product information, please contact sales. -:
