UNS F47006 Cast Iron Product Information -:- For detailed product information, please contact sales. -: **Product Overview: UNS F47006 Cast Iron (Ni-Resist Type D-2S)** UNS F47006 is a martensitic nickel-chromium corrosion-resistant cast iron, commonly known as **Ni-Resist Type D-2S**. It is specifically engineered to offer superior strength, hardness, and wear resistance compared to standard austenitic Ni-Resist grades, while maintaining good corrosion resistance, particularly in alkaline environments. Its unique microstructure makes it a premier material for demanding applications involving abrasion, corrosion, and stress. --- ### **1. Key International Standards & Designations** This alloy is recognized under several international standards systems, ensuring consistent quality and performance globally. * **UNS:** F47006 * **ASTM A439 / ASTM A571:** D-2S * **ISO 2892:** L-NiCuCr 15 6 2 (approximately equivalent, check specific properties for exact match) * **EN / DIN:** G-NiCuCr 15 6 2 (similar) * **Common Trade Name:** Ni-Resist Type D-2S --- ### **2. Chemical Composition (Typical % by Weight)** The composition is carefully balanced to produce its characteristic martensitic matrix. | Element | Min (%) | Max (%) | Primary Function | | :--- | :--- | :--- | :--- | | **Nickel (Ni)** | 13.5 | 17.5 | Stabilizes martensite, enhances toughness and corrosion resistance. | | **Chromium (Cr)** | 1.5 | 2.5 | Increases hardenability, improves resistance to oxidation and wear. | | **Copper (Cu)** | 5.5 | 7.5 | Promotes pearlite/martensite formation, improves corrosion resistance. | | **Manganese (Mn)** | 0.5 | 1.5 | Deoxidizer, aids in carbide formation and strength. | | **Silicon (Si)** | 1.0 | 2.0 | Improves fluidity for casting, strengthens the ferrite. | | **Carbon (C)** | 2.7 | 3.2 | Provides hardness and wear resistance. | | **Phosphorus (P)** | - | 0.08 max | Kept low to prevent brittleness. | | **Sulfur (S)** | - | 0.12 max | Controlled for casting soundness. | | **Iron (Fe)** | **Balance** | | Forms the matrix of the alloy. | --- ### **3. Typical Physical & Mechanical Properties** The properties can vary slightly based on casting section size and heat treatment. **A. Physical Properties:** * **Density:** ~7.6 g/cm³ (0.275 lb/in³) * **Melting Range:** ~1170 - 1260 °C (2140 - 2300 °F) * **Coefficient of Thermal Expansion (20-400°C):** ~12.0 x 10⁻⁶ /°C * **Thermal Conductivity:** ~30 W/m·K * **Magnetic Response:** **Magnetic** (due to its martensitic structure). **B. Mechanical Properties (As-Cast or Heat-Treated):** * **Tensile Strength:** 450 - 620 MPa (65 - 90 ksi) * **Yield Strength (0.2% Offset):** 275 - 480 MPa (40 - 70 ksi) * **Elongation (% in 50mm):** 2 - 8% (relatively low, characteristic of a hard, wear-resistant material) * **Hardness (Brinell):** 240 - 320 HB (Approx. 25 - 35 HRC) * **Modulus of Elasticity:** 140 - 160 GPa (20 - 23 x 10⁶ psi) --- ### **4. Key Characteristics & Advantages** * **High Strength & Hardness:** Its martensitic matrix provides excellent resistance to abrasive wear and deformation under load. * **Good Corrosion Resistance:** Performs very well in alkaline solutions, saltwater, seawater (superior to carbon steels), and many organic compounds. Resistance to mineral acids is limited. * **Outstanding Wear Resistance:** Ideal for applications involving sliding wear, abrasion, and galling. * **Pressure Tightness:** Suitable for components requiring sealing against liquids or gases. * **Machinability:** Fair to good with appropriate tools and techniques, though harder than standard gray or austenitic ductile irons. --- ### **5. Typical Applications** UNS F47006 (Ni-Resist D-2S) is specified for heavy-duty components where wear and corrosion are concurrent challenges. * **Valves & Pumps:** High-pressure valve bodies, pump casings, impellers, and sleeves handling corrosive/abrasive slurries or seawater. * **Marine & Offshore:** Propeller shafts, stern bearings, seawater pump components, deck machinery parts exposed to saltwater spray. * **Power Generation:** Flue gas desulfurization (FGD) system components, fan blades in corrosive environments. * **Industrial Machinery:** Gears, rollers, liners, and guides in processing equipment subject to wear. * **Automotive & Diesel:** Turbocharger housings, high-performance cylinder liners (where applicable). * **Paper & Pulp Industry:** Disc refiners, pump components handling corrosive liquors with solids. --- ### **6. Heat Treatment** Components are often used in the as-cast condition. However, to optimize mechanical properties and stress relief, they may undergo: * **Stress Relieving:** Heating to ~600°C (1110°F) to reduce residual casting stresses. * **Hardening & Tempering:** Can be oil-quenched and tempered to achieve specific hardness and toughness profiles for extreme wear applications. ### **Summary** **UNS F47006 (Ni-Resist D-2S)** is a high-performance martensitic nickel-chromium cast iron that bridges the gap between corrosion-resistant alloys and wear-resistant steels. Its combination of substantial strength, good hardness, and reliable corrosion resistance—particularly in alkaline and marine environments—makes it an indispensable engineering material for critical components across the marine, energy, chemical processing, and heavy machinery industries. Compliance with major standards like ASTM A439 ensures its reliability for international projects and supply chains. -:- For detailed product information, please contact sales. -: UNS F47006 Cast Iron Specification Dimensions Size： Diameter 20-1000 mm Length <6596 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. -: UNS F47006 Cast Iron Properties -:- For detailed product information, please contact sales. -:
