Sandvik SAF 2205 Hollow Bar Product Information -:- For detailed product information, please contact sales. -: # **Product Name: Sandvik SAF 2205 Hollow Bar (UNS S32205 / EN 1.4462)** ## **Introduction** Sandvik SAF 2205 Hollow Bar is a high-performance, **seamless, tubular bar stock** specifically engineered for the efficient manufacturing of **machined sleeves, bushings, rings, and hollow components**. Offering the superior properties of premium duplex stainless steel in a near-net-shape form, it provides significant advantages over solid bar by **reducing material waste, machining time, and overall production costs**. This product is ideal for applications requiring corrosion-resistant parts with bores, such as those found in pumps, valves, and marine equipment, where strength, SCC resistance, and dimensional stability are critical. ## **Key Features** * **Near-Net-Shape Efficiency:** The pre-formed hollow geometry drastically reduces the amount of material to be removed during machining, leading to **lower material costs, reduced machining time, and less tool wear**. * **Superior Duplex Performance:** Delivers the full benefit of SAF 2205, including **over double the yield strength of 316L**, excellent resistance to chloride stress corrosion cracking (SCC), and robust pitting/crevice corrosion resistance (PREN ≥ 34). * **Excellent Consistency & Machinability:** Produced with tight dimensional tolerances, concentricity, and a homogeneous microstructure, ensuring predictable machining behavior and final part performance. Compatible with Sandvik's SANMAC® machining-optimized variants. * **Broad Size Range:** Available in a wide variety of outer diameters (OD), wall thicknesses (WT), and lengths to suit diverse component designs. --- ## **1. Chemical Composition (Typical Weight % - Sandvik Specification)** The composition is precisely controlled to meet the premium UNS S32205 specification for consistent performance. | 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:** Guarantees the higher minimum Molybdenum (≥3.0%) and Nitrogen (≥0.14%) content of UNS S32205. **PREN Calculation:** PREN = %Cr + 3.3(%Mo) + 16(%N) ≥ **34** --- ## **2. Physical & Mechanical Properties (Solution Annealed Condition)** | 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** | **Dimensional Characteristics:** * **Manufacturing Process:** Typically produced by **extrusion or piercing** of a billet, followed by cold drawing/pilgering and heat treatment to achieve precise dimensions and properties. * **Tolerances:** Supplied with tight tolerances on OD, ID, and wall thickness per customer specification or standards like DIN 2391-2. * **Surface Finish:** Peeled, turned, or polished surfaces are available. --- ## **3. Product Forms & Target Applications** **Available Product Forms:** * **Seamless Hollow Bars:** In random or cut lengths. * **Dimensions:** Wide range of OD (e.g., 30mm to 300mm+) and WT to OD ratios. * **Condition:** Solution annealed and pickled, ready for machining. Stress-relieved conditions also available for improved machinability. **Primary Applications (Machined Hollow Components):** SAF 2205 Hollow Bar is specifically selected to manufacture corrosion-resistant parts with an integral bore: * **Pump & Compressor Components:** Sleeves, wear rings, bushings, throttle bushings, and balance drums. * **Valve Components:** Valve bodies (for smaller sizes), bonnets, bushings, and gland followers. * **Mechanical Seals & Glands:** Seal housings and rotating sleeves. * **Marine & Offshore:** Stern tube bushings, bearing sleeves, and propeller shaft liners. * **Oil & Gas:** Sleeves for downhole tools, choke parts, and instrumentation housings. * **General Machinery:** Hydraulic cylinders, actuator barrels, and coupling sleeves for corrosive environments. --- ## **4. International Standards & Approvals** Sandvik SAF 2205 Hollow Bar complies with material standards for duplex stainless steel bars and can be supplied to dimensional standards for tubes. | Standard Type | Standard Number & Designation | Notes | | :------------------ | :--------------------------------------------------------------------------------------------------------------------------- | :-------------------------------------------------------------------- | | **Unified Numbering System (UNS)** | **S32205** | The premium duplex material specification. | | **EN / EURONORM (Europe)** | **1.4462** | Standard European material number. | | **ASTM (USA)** | **ASTM A276** (Standard Specification for Stainless Steel Bars and Shapes) - For material properties. | Hollow bar is often treated as a "bar" product for material certification. | | | **ASTM A479** (Spec. for SS Bars & Shapes for Pressure Vessels) | Applicable for pressure part components. | | **Dimensional Standards** | **DIN 2391-2** (Seamless precision steel tubes), or customer-specific drawings. | Governs dimensional tolerances for hollow bar. | | **NACE MR0175/ISO 15156** | **Compliant** (with proper final heat treatment and hardness control) | Suitable for sourcing material for sour service components. | | **Key Procurement Specification** | **Sandvik Material Data Sheet for SAF 2205** plus a **detailed dimensional drawing** (OD, WT, length, tolerances). | Explicitly state requirement for **Hollow Bar** or **Seamless Hollow Bar**. | --- ## **Critical Technical & Procurement Note** **Hollow Bar is a specialized product form designed for machining efficiency.** 1. **Procurement Specification:** Clearly specify **"Sandvik SAF 2205 Hollow Bar"** and provide precise **dimensional requirements**: Outside Diameter (OD), Inside Diameter (ID) or Wall Thickness (WT), length, and tolerances (e.g., h11 for OD, H11 for ID). 2. **Condition:** Typically supplied in **Solution Annealed & Pickled** condition. For optimal machinability, inquire about **stress-relieved** or **SANMAC®-enhanced** versions of hollow bar, which offer improved chip breaking and tool life. 3. **Certification:** Require a **Sandvik Certificate of Conformity** that includes: * Chemical analysis confirming UNS S32205. * Mechanical properties (from test coupon). * Dimensional inspection report. * Heat treatment certificate. 4. **Design Advantage:** Utilizing hollow bar is most economical when the finished part has a **large length-to-bore ratio**. It eliminates the need for deep-hole drilling, a costly and time-consuming operation on solid bar. 5. **Application:** This product is intended for **component manufacturing via machining**. Its use significantly reduces the "buy-to-fly" ratio, making it a cost-effective and sustainable choice for producing hollow duplex stainless steel parts. -:- For detailed product information, please contact sales. -: Sandvik SAF 2205 Hollow Bar Specification Dimensions Size： Diameter 20-1000 mm Length <7295 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 SAF 2205 Hollow Bar Properties -:- For detailed product information, please contact sales. -:
