Sandvik SANMAC SAF 2205 Bar Steel Product Information -:- For detailed product information, please contact sales. -: # **Product Name: Sandvik SANMAC SAF 2205 Bar (UNS S32205 / EN 1.4462)** ## **Introduction** Sandvik SANMAC SAF 2205 is the premier **duplex stainless steel bar product**, offering unmatched quality and consistency for high-performance machined components. As part of Sandvik's renowned **SANMAC** product line—dedicated to superior machinability and dimensional stability—this bar stock provides the **ideal combination of high strength, excellent corrosion resistance, and outstanding machining characteristics**. It is the material of choice for engineers requiring complex, high-integrity parts such as pump shafts, valve stems, fasteners, and fittings that must withstand aggressive environments while being efficiently produced. ## **Key Features** * **Superior Machinability:** The SANMAC production process optimizes the microstructure and inclusion morphology, resulting in significantly **improved chip breaking, longer tool life, higher cutting speeds, and better surface finish** compared to standard duplex bar stock. * **High Strength & Corrosion Resistance:** Delivers the full performance of premium duplex UNS S32205, with **over double the yield strength of 316L** and excellent resistance to chloride stress corrosion cracking (SCC), pitting, and crevice corrosion (PREN ≥ 34). * **Excellent Consistency & Dimensional Stability:** Produced with tight tolerances on chemistry, microstructure, and dimensions, ensuring predictable performance in both machining and final application. * **Broad Product Range:** Available in a wide variety of sizes, shapes (rounds, hexagons, squares), surface finishes, and conditions (hot/cold worked, turned, peeled, ground) to suit specific manufacturing needs. --- ## **1. Chemical Composition (Typical Weight % - Sandvik Specification)** The composition is tightly controlled to meet the premium UNS S32205 specification, ensuring optimal phase balance and corrosion resistance. | Element | Content (%) | Element | Content (%) | | :------------- | :------------ | :------------- | :---------- | | Chromium (Cr) | 22.0 - 23.0 | Nickel (Ni) | 4.5 - 6.5 | | Molybdenum (Mo)| **3.0 - 3.5** | **Nitrogen (N)**| **0.14 - 0.20** | | Manganese (Mn) | ≤ 2.0 | Copper (Cu) | ≤ 0.20 | | Silicon (Si) | ≤ 1.0 | Carbon (C) | ≤ 0.030 | | Phosphorus (P) | ≤ 0.030 | Sulfur (S) | ≤ 0.015 | | **Iron (Fe)** | **Balance** | | | **Key Quality Assurance:** Sandvik guarantees the premium **UNS S32205** composition, with the higher minimum Mo and N content essential for consistent, superior pitting resistance. **PREN Calculation:** PREN = %Cr + 3.3(%Mo) + 16(%N) ≥ **34** --- ## **2. Physical & Mechanical Properties (Typical - Solution Annealed Bar)** | Property | Value / Range | | :-------------------------------------------- | :-------------------------------- | | Density | 7.80 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) | 240 - 300 HBW | | **Impact Toughness (Charpy V-notch, min.)** | **≥ 100 J at -40°C** | | **Machinability Index** | **~60%** (vs. 100% for 1215 steel)| --- ## **3. Product Forms & Target Applications** **Available Product Forms (Bar):** * **Round Bars:** Drawn, turned, peeled, ground, centerless ground. * **Hexagon & Square Bars.** * **Billets & Forging Stock.** * **Wire Rod** for further processing. **Primary Applications (Machined Components):** SANMAC SAF 2205 bar is specifically selected for demanding, corrosion-resistant machined parts: * **Valve & Pump Components:** Shafts, stems, sleeves, bushings, impellers, and valve trim (gates, seats) for chemical process, oil & gas, and marine industries. * **Fasteners & Bolting:** High-strength studs, bolts, nuts, and threaded rods for flanged connections in corrosive environments (e.g., offshore platforms, desalination plants). * **Fittings & Connectors:** Machined fittings for high-pressure duplex piping systems. * **Shafts & Spindles:** Drive shafts, mixer shafts, and agitators in pulp & paper and chemical processing. * **Oil & Gas Downhole & Wellhead:** Precision machined parts for Christmas trees, manifolds, and tooling. --- ## **4. International Standards & Approvals** Sandvik SANMAC SAF 2205 bar complies with all major international standards for duplex stainless steel bar. | Standard Type | Standard Number & Designation | Notes | | :------------------ | :--------------------------------------------------------------------------------------------------------------------------- | :-------------------------------------------------------------------- | | **Unified Numbering System (UNS)** | **S32205** | The premium duplex bar specification. | | **EN / EURONORM (Europe)** | **1.4462** | Standard European material number. | | | **EN 10088-3** (Bars, rods, wire rod) | The key European product standard for bars. | | **ASTM (USA)** | **ASTM A276** (Standard Specification for Stainless Steel Bars and Shapes)

This is not a generic bar stock.** 1. **Procurement:** Specify **"Sandvik SANMAC SAF 2205 Bar to UNS S32205"** to guarantee receipt of the optimized product. Referencing the Sandvik material data sheet (2059) is highly recommended. 2. **Machinability:** Leverage Sandvik's machining data and recommendations (speeds, feeds, tool geometries) to maximize productivity. The improved machinability directly reduces manufacturing cost. 3. **Condition:** Bars are typically supplied in a **solution annealed and quenched (+pickled) condition** suitable for machining. Cold-worked conditions are available for even higher strength. 4. **Certification:** Require a **Sandvik Certificate of Conformity** that includes chemical analysis (confirming S32205 spec), mechanical properties, and often a statement confirming the SANMAC quality level for machinability. Microcleanliness ratings may also be provided. 5. **Application:** This material is designed for **components that will be machined**. Its superior consistency ensures reliable performance in automated production and critical end-use environments. -:- For detailed product information, please contact sales. -: Sandvik SANMAC SAF 2205 Bar Steel Specification Dimensions Size： Diameter 20-1000 mm Length <7291 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. -: Sandvik SANMAC SAF 2205 Bar Steel Properties -:- For detailed product information, please contact sales. -:
