Schmolz + Bickenbach UGIPLEX UGI 4362 Low Nickel Bar Product Information -:- For detailed product information, please contact sales. -: # **Product Name: Schmolz + Bickenbach UGIPLEX® UGI 4362 Bar (Lean Duplex Stainless Steel Bar)** ## **Introduction** Schmolz + Bickenbach UGIPLEX® UGI 4362 is a **lean duplex stainless steel bar product** engineered to provide an **optimal balance of high mechanical strength, good corrosion resistance, and excellent cost-effectiveness**. Characterized by its **low nickel content and controlled nitrogen addition**, this alloy delivers approximately **double the yield strength of standard austenitic grades like 304/304L** while offering superior resistance to stress corrosion cracking (SCC). UGIPLEX UGI 4362 is designed for structural, fastener, and machined component applications where the high strength of duplex stainless steel is required, but the full corrosion resistance and cost of standard or super duplex grades are not justified. ## **Key Features** * **High Strength & Weight Savings:** Delivers yield strength typically ≥ 500 MPa, enabling significant material savings and lightweight design in structural components and fasteners. * **Excellent Stress Corrosion Cracking (SCC) Resistance:** Provides vastly superior resistance to chloride-induced SCC compared to 300-series austenitic steels, a key advantage in environments containing chlorides or coastal atmospheres. * **Cost-Effective Alloy Design:** The "lean" chemistry, with reduced nickel and molybdenum content, offers a more affordable and price-stable alternative to standard duplex grades (e.g., 2205). * **Good Machinability and Weldability:** Can be machined and welded using standard practices adapted for duplex stainless steels, with appropriate filler metals. --- ## **1. Chemical Composition (Typical Weight % - S+B UGIPLEX Specification)** The composition is optimized for a stable duplex microstructure with lean alloying. | Element | Content (%) | Element | Content (%) | | :------------- | :------------ | :------------- | :---------- | | Chromium (Cr) | 22.0 - 24.0 | Nickel (Ni) | 3.0 - 4.5 | | Molybdenum (Mo)| 0.10 - 0.60 | **Nitrogen (N)**| **0.08 - 0.20** | | Manganese (Mn) | 4.0 - 6.0 | Copper (Cu) | 0.10 - 0.80 | | Silicon (Si) | ≤ 0.8 | Carbon (C) | ≤ 0.030 | | Phosphorus (P) | ≤ 0.035 | Sulfur (S) | ≤ 0.015 | | **Iron (Fe)** | **Balance** | | | **Key Alloying Strategy:** **High Manganese (Mn)** partially replaces Nickel (Ni) to stabilize the austenite phase, while **Nitrogen (N)** strengthens the alloy and balances the microstructure. **PREN Calculation:** PREN = %Cr + 3.3(%Mo) + 16(%N) ≈ **25 - 28** --- ## **2. Physical & Mechanical Properties (Typical for Solution Annealed Bar)** | Property | Value / Range | | :-------------------------------------------- | :-------------------------------- | | Density | 7.7 g/cm³ | | Modulus of Elasticity | 200 GPa | | **Tensile Strength (Rm)** | **700 - 900 MPa** | | **Yield Strength (Rp0.2)** | **≥ 500 MPa** | | **Elongation (A in 5D)** | **≥ 25 %** | | Hardness (Brinell) | 250 - 310 HBW | | **Impact Toughness (Charpy V-notch)** | **≥ 100 J at -20°C** | | **Machinability** | Good, requires appropriate tooling and parameters for duplex alloys. | --- ## **3. Product Forms & Applications** **Available Product Forms (Bar):** * **Round Bars:** Black, peeled, turned, or ground finish. * **Hexagon and Square Bars.** * **Wire Rod.** * **Forging Stock.** **Target Applications:** UGIPLEX UGI 4362 bar is ideal for replacing 304/304L and 316/316L in applications where higher strength or SCC resistance is the primary driver: * **Construction & Infrastructure:** Reinforcement bars (rebar), fasteners (bolts, studs), structural sections, and bridge components in corrosive atmospheres (e.g., de-icing salt, coastal areas). * **Transportation:** Axles, chassis components, and fasteners for railcars, trucks, and trailers. * **Water & Wastewater Treatment:** Shafts, fasteners, and structural parts in treatment plants and desalination facilities. * **Material Handling:** Components for conveyor systems, hoppers, and containers requiring higher wear resistance. * **General Machined Components:** Pump shafts, valve stems, and fittings for moderately corrosive environments. --- ## **4. International Standards & Approvals** UGIPLEX UGI 4362 corresponds to standardized lean duplex grades. | Standard Type | Standard Number & Designation | Notes | | :------------------ | :--------------------------------------------------------------------------------------------------------------------------- | :-------------------------------------------------------------------- | | **EN / EURONORM (Europe)** | **1.4362** | The most common European material number for this lean duplex alloy type. | | | EN 10088-3: Stainless steel bars for general purposes. | | | **Unified Numbering System (UNS)** | **S32003** or similar lean duplex designation. | May be supplied to meet the characteristics of UNS S32003. | | **ASTM (USA)** | Can be supplied to meet key mechanical properties, but may not have a direct, universally listed ASTM grade equivalent. | Often specified by agreement based on EN 1.4362. | | **Key Procurement Specification** | **Schmolz + Bickenbach UGIPLEX® UGI 4362 Technical Datasheet.** | For guaranteed properties, the proprietary UGIPLEX datasheet should be referenced. | --- ## **Critical Technical & Procurement Note** **UGIPLEX UGI 4362 is a proprietary lean duplex product from Schmolz + Bickenbach. Its selection should be based on a clear understanding of its performance envelope.** 1. **Procurement Specification:** Specify **"Schmolz + Bickenbach UGIPLEX UGI 4362 (EN 1.4362)"** to ensure receipt of the correct grade. Reference to the manufacturer's datasheet is recommended. 2. **Corrosion Performance Positioning:** Its corrosion resistance is generally positioned **between AISI 304L and 316L**, with significantly better **SCC resistance than both**. It is **not suitable** for immersion in seawater or other high-chloride environments where pitting is the dominant failure mode. For such conditions, standard duplex (e.g., 2205 / 1.4462) is required. 3. **Fabrication:** * **Machining:** Requires tools and parameters suitable for duplex stainless steels (positive rake angles, rigid setup). Chip breakers are advisable. * **Welding:** Use appropriate lean duplex or slightly over-alloyed filler metals (e.g., 22.8.3L type). Control heat input to maintain a balanced microstructure. 4. **Certification:** Require a **material test certificate** from Schmolz + Bickenbach confirming compliance with EN 1.4362, including chemical analysis (noting the low Ni, high Mn, high N profile) and mechanical properties. 5. **Economic Rationale:** The primary advantage is a **high strength-to-cost ratio** combined with **good SCC resistance**. It is an economical upgrade path from 304/316 when these grades fail due to insufficient strength or SCC, but where the full capability of 2205 is not needed. -:- For detailed product information, please contact sales. -: Schmolz + Bickenbach UGIPLEX UGI 4362 Low Nickel Bar Specification Dimensions Size： Diameter 20-1000 mm Length <7307 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. -: Schmolz + Bickenbach UGIPLEX UGI 4362 Low Nickel Bar Properties -:- For detailed product information, please contact sales. -:
