Industeel URANUS® 35N 23.04 Duplex Stainless Steel with PREN = 24 Product Information -:- For detailed product information, please contact sales. -: **Product Name:** Industeel URANUS® 35N (UNS S31212 / 1.4565) – Lean Duplex Stainless Steel with PREN = 24 **Introduction:** Industeel URANUS® 35N (23.04) is a **lean duplex stainless steel** belonging to the URANUS® family. It is specifically engineered to offer a cost-effective alternative to standard austenitic grades like 316L and carbon steel with cladding, providing a **balanced combination of medium corrosion resistance and significantly higher strength**. With a Pitting Resistance Equivalent Number (PREN) of approximately 24, it is designed for environments where excellent mechanical performance is required, but the full corrosion resistance of standard duplex (e.g., 2205) is not necessary. Its low nickel and molybdenum content makes it a more economical and stable-alloying choice. **Key Features:** * **High Strength & Weight Savings:** Delivers nearly double the yield strength of standard austenitic grades (316L), enabling substantial weight reduction and savings in structural and pressure equipment. * **Good Corrosion Resistance:** Offers superior resistance to stress corrosion cracking (SCC) and better general/pitting corrosion resistance than 304L/316L in many mild to moderately corrosive environments (e.g., chlorides, weak acids). * **Excellent Value Proposition:** Provides an optimal performance-to-cost ratio by reducing reliance on expensive alloying elements (Ni, Mo) while maintaining the duplex advantage of strength and SCC resistance. * **Good Weldability & Fabricability:** Can be welded using standard procedures with appropriate lean duplex or overmatching filler metals. --- **1. Chemical Composition (Typical Weight %)** The composition is optimized for a stable austenite-ferrite microstructure with lean alloying. | Element | Content (%) | Element | Content (%) | | :------------- | :------------ | :------------- | :---------- | | Chromium (Cr) | 23.0 - 25.0 | Nickel (Ni) | 3.0 - 5.0 | | Molybdenum (Mo)| 0.10 - 0.60 | Nitrogen (N) | 0.10 - 0.20 | | Manganese (Mn) | 2.00 - 3.50 | Copper (Cu) | 0.50 - 1.50 | | Silicon (Si) | ≤ 1.00 | Carbon (C) | ≤ 0.030 | | Phosphorus (P) | ≤ 0.035 | Sulfur (S) | ≤ 0.015 | | **Iron (Fe)** | **Balance** | | | **PREN Calculation:** PREN = %Cr + 3.3(%Mo) + 16(%N) ≈ **24** --- **2. Physical & Mechanical Properties (Typical at Room Temperature - Annealed)** | Property | Value / Range | | :-------------------------------------------- | :-------------------------------- | | Density | ≈ 7.70 g/cm³ | | Melting Range | ≈ 1420 - 1470 °C | | Specific Heat Capacity (20°C) | ≈ 500 J/kg·K | | Thermal Conductivity (20°C) | ≈ 18 W/m·K | | Coefficient of Thermal Expansion (20-100°C) | ≈ 13.5 x 10⁻⁶ /K | | Modulus of Elasticity | ≈ 200 GPa | | **Tensile Strength (Rm)** | **680 - 880 MPa** | | **Yield Strength (Rp0.2)** | **≥ 500 MPa** | | **Elongation (A)** | **≥ 25 %** | | Hardness (Brinell) | ≈ 260 HBW | | Impact Toughness (Charpy V-notch) | Typically > 100 J at -20°C | --- **3. Product Forms & Applications** **Available Product Forms:** * Plate and Sheet * Welded Pipe & Tube * Bar and Wire * Welding Consumables **Target Applications:** * **Construction & Structural:** Bridges, concrete reinforcement bars (rebar), load-bearing structures in mildly corrosive atmospheres (coastal, de-icing salt environments). * **Water & Waste Treatment:** Tanks, basins, piping, and structural components in freshwater and wastewater treatment plants. * **Pulp & Paper Industry:** Certain sections of pulp processing equipment where high strength is beneficial. * **Chemical & Process Industry:** Tanks, vessels, and piping for less aggressive chemical media (e.g., organic acids, sulfates) where SCC resistance is critical. * **Transportation:** Chassis components, tanker trailers for non-aggressive cargoes. * **Energy:** Flue gas cleaning systems, structural parts in power generation. --- **4. International Standards & Approvals** URANUS® 35N corresponds to specific lean duplex standard grades. | Standard Type | Standard Number & Designation | Notes | | :------------------ | :------------------------------------------------------------------------------------------------------------------------------------------------------------ | :----------------------------------------------------------------------------- | | **Unified Numbering System (UNS)** | **S31212** (Proposed) | Common reference, though not as universally listed as standard duplex grades. | | **EN / EURONORM (Europe)** | **1.4565** (Common material number) | The most recognized standard designation for this alloy type. | | | EN 10088-2: Stainless steel sheet/plate, strip | | | **ASTM (USA)** | May be supplied to meet key mechanical and corrosion properties of similar lean duplex grades under specific customer agreement. | Not covered by a direct, common ASTM grade like 2205. Proprietary/Modified grades are common. | | **Other National Standards** | May have equivalents in various national standards, often categorized as a "lean duplex" or "low-nickel duplex" grade. | Specification by chemical analysis and guaranteed mechanical properties is key. | **Important Note:** Industeel URANUS® 35N is a **proprietary lean duplex grade**. While it aligns with the general characteristics of UNS S31212 / EN 1.4565, its exact properties and availability should be confirmed with Industeel. It is specifically designed for applications where the **high strength of duplex is the primary driver**, offering a more economical solution than standard duplex grades. Selection should be based on a thorough corrosion assessment against the specific service environment. -:- For detailed product information, please contact sales. -: Industeel URANUS® 35N 23.04 Duplex Stainless Steel with PREN = 24 Specification Dimensions Size： Diameter 20-1000 mm Length <7273 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. -: Industeel URANUS® 35N 23.04 Duplex Stainless Steel with PREN = 24 Properties -:- For detailed product information, please contact sales. -:
