Industeel URANUS® 45N 22Cr 3Mo Duplex Stainless Steel with PREN = 33 or 34 Product Information -:- For detailed product information, please contact sales. -: **Product Name:** Industeel URANUS® 45N (22Cr-3Mo Duplex Stainless Steel, PREN = 33-34) **Introduction:** Industeel URANUS® 45N is a high-performance, **standard (or "classic") duplex stainless steel** engineered to deliver an exceptional balance of **high strength, superior corrosion resistance, and excellent cost-effectiveness**. With a typical Pitting Resistance Equivalent Number (PREN) of 33-34, it provides outstanding resistance to chloride-induced stress corrosion cracking (SCC), pitting, and crevice corrosion, positioning it as a direct and often superior alternative to common austenitic grades like 316L and 317L. It represents the industry workhorse for demanding environments where reliability, longevity, and structural efficiency are paramount. **Key Features:** * **Exceptional Strength-to-Weight Ratio:** Yield strength is **over double that of standard austenitic stainless steels (e.g., 316L)**, enabling significant weight reduction, thinner sections, and lower lifetime costs for pressure vessels and structures. * **Superior & Proven Corrosion Resistance:** Excellent resistance to chloride stress corrosion cracking (SCC) and robust resistance to pitting and crevice corrosion in a wide range of aggressive media, including seawater, chemical process streams, and acidic brines. * **Excellent Fabricability & Weldability:** Designed for reliable welding and forming using industry-standard practices, with a well-established portfolio of matching filler metals (e.g., 22.9.3.L type). * **Optimal Lifecycle Cost:** Offers the best value proposition within the duplex family, bridging the gap between standard stainless steels and more expensive super duplex or nickel alloys for countless applications. --- **1.

Product Forms & Applications** **Available Product Forms:** * Plate and Sheet * Hot Rolled and Cold Drawn Bar * Seamless and Welded Pipe & Tube * Forgings and Fittings **Primary Applications:** URANUS® 45N is the quintessential duplex grade for severe environments across major industries: * **Oil & Gas Industry:** Production tubing, flowlines, separators, heat exchangers, and pressure vessels in offshore, subsea, and sour (H₂S) service. Fully compliant with **NACE MR0175/ISO 15156** standards for sour service. * **Chemical & Petrochemical Processing:** Reactors, columns, tanks, and piping for chlorides, organic acids, and aggressive chemical media. * **Pulp & Paper Industry:** Digester impregnation vessels, bleach plants, and liquor handling systems. * **Marine & Offshore:** Seawater cooling systems, pumps, valves, propellers, and deck equipment. * **Desalination & Water Treatment:** High-pressure reverse osmosis (RO) membranes, piping, and pumps in multi-stage flash (MSF) and RO plants. * **Pollution Control:** Flue gas desulfurization (FGD) scrubbers, ducting, and absorber towers. * **Chemical Tankers:** Cargo tanks and unloading systems. * **Architecture & Construction:** Structural components, bridges, and façades in highly corrosive coastal and industrial atmospheres. --- **4.

For procurement, it is essential to specify compliance with these standard designations (e.g., ASTM A240 S32205) to guarantee the published properties. Material must be supplied in the **solution annealed and quenched condition**. All welding must use qualified procedures with appropriate duplex consumables (e.g., AWS A5.9 ER2209) to preserve corrosion resistance. Always require a **certified material test report (CMTR)** from the manufacturer. -:- For detailed product information, please contact sales. -: Industeel URANUS® 45N 22Cr 3Mo Duplex Stainless Steel with PREN = 33 or 34 Specification Dimensions Size： Diameter 20-1000 mm Length <7274 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® 45N 22Cr 3Mo Duplex Stainless Steel with PREN = 33 or 34 Properties -:- For detailed product information, please contact sales. -:
