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 MAXEL® Tooling Alloy Steel Flange, AISI 4140 Modified Product Information -:- For detailed product information, please contact sales. -: Crucible Steel Flange MAXEL® Tooling Alloy Steel Flange, AISI 4140 Modified Synonyms -:- For detailed product information, please contact sales. -:

Crucible Steel MAXEL® Tooling Alloy Steel, AISI 4140 Modified Product Information -:- For detailed product information, please contact sales. -: # **Product Introduction: Crucible Steel MAXEL® (Modified AISI 4140) Tooling Alloy Steel** Crucible Steel MAXEL® is a premium, oil-hardening alloy steel specifically engineered as a **modified and enhanced version of the industry-standard AISI 4140**. It is designed to bridge the gap between general-purpose alloy steels and dedicated tool steels, offering a superior combination of **high strength, excellent toughness, good hardenability, and exceptional dimensional stability during heat treatment**. MAXEL® is optimized for demanding tooling, die, and machinery component applications where the performance of standard 4140 is insufficient, but the full alloy content and cost of a traditional tool steel like A2 or D2 may not be justified. The "modified" aspect of its chemistry involves tighter compositional controls and strategic adjustments to elements like silicon, molybdenum, and vanadium. These enhancements provide improved through-hardening characteristics, better resistance to tempering, superior fracture toughness, and reduced susceptibility to quench cracking. MAXEL® is the material of choice for high-stress components that require reliable performance under cyclic loading, impact, or high pressure, making it a versatile and cost-effective engineering solution for critical applications. --- ## **1. Chemical Composition (Weight %)** MAXEL® builds upon the 4140 foundation with refined alloy ranges and additions for enhanced performance. | **Element** | **Carbon (C)** | **Chromium (Cr)** | **Molybdenum (Mo)** | **Manganese (Mn)** | **Silicon (Si)** | **Vanadium (V)** | **Sulfur (S)/Phosphorus (P)** | | :--- | :--- | :--- | :--- | :--- | :--- | :--- | :--- | | **Content** | 0.38 - 0.43 | 0.90 - 1.20 | 0.20 - 0.30 | 0.75 - 1.00 | **0.30 - 0.60** | **0.03 - 0.08** | ≤ 0.025 (each) | | **Role** | Provides core strength and hardenability. Optimized for a balance of hardness and toughness. | Increases hardenability, wear resistance, and provides moderate corrosion resistance. | Enhances hardenability (especially in thicker sections), improves strength, and increases resistance to tempering. | Primary agent for hardenability and strength; aids in deoxidation. | **Enhanced level.** Increases strength and hardness, significantly improves resistance to tempering and oxidation. | **Key modifier.** Refines grain structure, enhancing toughness, strength, and resistance to fatigue. | Impurities strictly controlled to maximize cleanliness, ductility, and impact strength. | *Note: Iron (Fe) constitutes the remainder. Compared to standard 4140 (C: 0.38-0.43, Cr: 0.8-1.1, Mo: 0.15-0.25, Si: 0.15-0.35), MAXEL® typically features higher and controlled Si, Mo, and the intentional addition of V.* --- ## **2. Physical & Mechanical Properties** *Properties are highly dependent on the heat-treated condition. Commonly used in the quenched and tempered state at various hardness levels (e.g., 28-36 HRC for tough components, or 45-52 HRC for wear applications).* * **Density:** ~7.85 g/cm³ (0.284 lb/in³) * **Modulus of Elasticity:** ~205 GPa (29.7 x 10⁶ psi) * **Thermal Conductivity:** Moderate. * **Hardenability:** **Excellent.** The modified composition provides very good through-hardening in substantial sections (exceeding standard 4140), typically represented by a high ideal critical diameter (D_I). * **Hardness (Typical Working Range):** **28 - 52 HRC.** Highly versatile. * **High Toughness:** 28-36 HRC (Tempered at ~540-650°C / 1000-1200°F) * **High Strength/Wear:** 45-52 HRC (Tempered at ~205-425°C / 400-800°F) * **Tensile & Yield Strength:** **Very High.** At a hardness of 50 HRC, tensile strength can exceed 1650 MPa (240 ksi). Offers an excellent strength-to-toughness ratio. * **Impact Toughness (Charpy):** **Exceptional for its strength level.** The fine-grained vanadium-modified microstructure provides superior fracture toughness compared to standard 4140, especially in the transverse direction. * **Fatigue Strength:** **Excellent.** Well-suited for components undergoing cyclic stress. * **Dimensional Stability:** **Very Good.** When properly oil quenched and tempered, distortion is predictable and manageable, superior to many water-hardening steels. --- ## **3. Heat Treatment** * **Annealing:** Heat to 830-860°C (1525-1580°F), slow cool. Annealed hardness: ≤ 217 HB. * **Normalizing:** Heat to 870-900°C (1600-1650°F), air cool. Prepares for hardening and refines grain structure. * **Austenitizing (for hardening):** **830-860°C (1525-1580°F).** A common temperature is **845-855°C (1555-1575°F)**. * **Quenching:** **Oil quench.** Use a fast, well-agitated oil. The enhanced hardenability allows for full hardening in thicker sections than standard 4140 with reduced risk of distortion. * **Tempering:** **Mandatory.** Temper immediately after quenching. Temperature is selected based on desired hardness and toughness. * **For High Toughness (28-36 HRC):** Temper at **540-650°C (1000-1200°F)** for 1-2 hours per inch of thickness. * **For High Strength (45-52 HRC):** Temper at **205-425°C (400-800°F)**. * **Avoid the 375-475°C (700-900°F) range** for extended times to minimize temper embrittlement risk. A double temper is often beneficial. --- ## **4. Key Applications** MAXEL® is an ideal upgrade for components where standard 4140 fails or requires a safety factor. * **High-Strength Tooling & Die Components:** Die holders, bolster plates, mold bases, and injection molding machine components. * **Heavy-Duty Machinery Parts:** Gears, shafts, spindles, connecting rods, and hydraulic cylinder components subjected to high stress and fatigue. * **Oil & Gas and Aerospace Components:** Valve bodies, fittings, landing gear parts, and other critical structural applications. * **Plastic Molds:** For high-pressure structural foam molding or large molds requiring high strength and toughness. * **Machine Tool Structures:** Critical frames, slides, and clamps requiring stability and durability. --- ## **5. International Standards & Cross-References** MAXEL® is a proprietary modified version of AISI 4140/4142. It meets or exceeds the requirements of several high-quality specifications. * **AISI/SAE:** **Modified 4140/4142** * **UNS:** G41400 (as a reference base) * **ASTM:** Often conforms to **A829** for alloy steel plates with improved properties. * **European (EN):** Similar in performance to a premium-quality **1.7225 / 42CrMo4+** with enhanced toughness. * **Aerospace:** May meet specifications such as **AMS 6382** or **AMS 6529** for high-strength, high-toughness steel. * **Common Industry Equivalents:** Often compared to other proprietary "super 4140" grades like **Uddeholm Orvar 2**, **Böhler M202**, or **DIN 1.2312** modified for higher strength. --- ## **6. Advantages & Limitations** **Advantages (vs. Standard 4140):** * **Higher Hardenability & Strength:** Achieves better properties in larger cross-sections. * **Superior Toughness & Impact Strength:** The vanadium addition provides a finer grain and better fracture resistance. * **Improved Temper Resistance:** Higher silicon content helps retain hardness at elevated temperatures. * **Better Consistency & Cleanliness:** Tighter controls on composition and impurities. * **Reduced Risk of Quench Cracking:** More forgiving during heat treatment due to modified hardenability. **Limitations:** * **Higher Cost:** More expensive than commodity-grade 4140. * **Not a Stainless Steel:** Requires protection against corrosion. * **Not an Abrasion-Resistant Tool Steel:** Wear resistance at low hardness is inferior to dedicated tool steels like D2; for severe abrasion, surface hardening may be required. * **Requires Proper Heat Treatment:** To achieve its designed properties. --- ## **7. Summary** **Crucible Steel MAXEL® is a high-performance engineering steel that redefines the capabilities of the 4140 family.** It is not merely a material but a reliability upgrade for critical applications. By incorporating vanadium for grain refinement and optimizing silicon and molybdenum content, MAXEL® delivers a combination of deep hardenability, exceptional toughness, and high strength that standard 4140 cannot match. For engineers and designers working on high-stress tooling, heavy machinery, or structural components where failure is not an option, MAXEL® provides a proven, cost-effective material solution that enhances performance, extends service life, and reduces risk. It is the intelligent choice when the application demands more than standard 4140 but does not require the full specialization of a high-alloy tool steel. -:- For detailed product information, please contact sales. -: Crucible Steel MAXEL® Tooling Alloy Steel, AISI 4140 Modified Specification Dimensions Size： Diameter 20-1000 mm Length <6982 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 MAXEL® Tooling Alloy Steel, AISI 4140 Modified Properties -:- For detailed product information, please contact sales. -:
