Sandvik SANMAC SAF 2205 Hollow Bar Product Information -:- For detailed product information, please contact sales. -: # **Product Name: Sandvik SANMAC SAF 2205 Hollow Bar (UNS S32205 / EN 1.4462)** ## **Introduction** Sandvik SANMAC SAF 2205 Hollow Bar is the premier, seamless tubular bar stock engineered specifically for **high-productivity machining of hollow components**. Building upon the standard SAF 2205 hollow bar, the **SANMAC** designation represents a proprietary production process that optimizes the material for superior machinability. This product delivers the **perfect synergy of manufacturing efficiency and extreme performance**: it combines the **near-net-shape cost savings of hollow bar** with the **significantly improved chip control, extended tool life, and higher machining speeds** of the SANMAC grade. It is the optimal choice for mass-producing precision corrosion-resistant parts like sleeves, bushings, and valve components where total part cost is critical. ## **Key Features** * **Unmatched Machining Performance:** The SANMAC process refines inclusion morphology, leading to **excellent chip breakability, predictable tool wear, and the ability to use higher cutting speeds and feeds**. This can reduce machining time by 20-40% compared to standard duplex hollow bar. * **Near-Net-Shape Material Efficiency:** The pre-formed hollow geometry drastically reduces material waste versus solid bar, lowering raw material costs and machining time for parts with bores. * **Full Premium Duplex Properties:** Guarantees the complete mechanical strength (Yield ≥500 MPa) and corrosion resistance (PREN ≥ 34, excellent SCC resistance) of UNS S32205 duplex stainless steel. * **Exceptional Consistency:** Provides uniform microstructure and dimensional stability along the entire length, ensuring repeatable performance in automated, high-volume production runs. --- ## **1. Chemical Composition (Typical Weight % - Sandvik SANMAC Specification)** The chemistry meets the stringent UNS S32205 specification, with additional controls for machinability enhancement. | 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** | | | **Machinability Key:** The SANMAC advantage lies not in altered bulk chemistry, but in **advanced melt practice and inclusion shape control** (e.g., calcium treatment) to create favorable chip-breaking inclusions. **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** | | **Machinability Index (Comparative)** | **~60%** (vs. 100% for 1215 steel). **Superior to standard 2205 hollow bar.** | **Dimensional & Delivery Characteristics:** * **Process:** Produced via extrusion/piercing and cold finishing from a SANMAC-optimized billet. * **Tolerances:** Available with tight tolerances on OD, ID, and wall thickness (e.g., to DIN 2391-2 or custom specifications). * **Condition:** Supplied in **solution annealed and pickled** condition, ready for machining. Stress-relieved versions for enhanced stability are also available. * **Surface:** Peeled, turned, or polished finishes. --- ## **3. Product Forms & Target Applications** **Available Product Forms:** * **Seamless SANMAC Hollow Bars:** In cut lengths or random mill lengths. * **Size Range:** Comprehensive range of Outer Diameters (OD) and Wall Thicknesses (WT) to suit various component designs. * **Special Variants:** Can be supplied with added **Internal Boring (ID machining)** or **External Turning (OD machining)** to a "semi-finished" state for even greater cost savings. **Primary Applications (High-Volume Machined Hollow Parts):** This product is designed for cost-effective production of complex, hollow duplex components: * **Pump & Compressor Parts:** Wear rings, sleeves, throttle bushings, balance drums, and mechanical seal housings for chemical and seawater service. * **Valve Components:** Valve bonnets, gland followers, bushings, and smaller valve bodies. * **Fluid Power:** Hydraulic and pneumatic cylinder barrels for corrosive environments. * **Marine & Offshore:** Stern tube liners, bearing sleeves, and propeller shaft bushes. * **General Engineering:** Actuator barrels, coupling sleeves, and sensor housings requiring high strength and corrosion resistance. --- ## **4. International Standards & Approvals** The material complies with international duplex standards, with the SANMAC features as a proprietary enhancement. | Standard Type | Standard Number & Designation | Notes | | :------------------ | :--------------------------------------------------------------------------------------------------------------------------- | :-------------------------------------------------------------------- | | **Unified Numbering System (UNS)** | **S32205** | The base material specification for chemistry and core properties. | | **EN / EURONORM (Europe)** | **1.4462** | Standard European material number. | | **ASTM (USA)** | **ASTM A276** (Standard Specification for Stainless Steel Bars and Shapes) | The material is certified to this bar standard. | | **Dimensional Standards** | **DIN 2391-2** (Seamless precision steel tubes), or customer-specific drawing tolerances. | Governs dimensional accuracy. | | **NACE MR0175/ISO 15156** | **Enabling Compliance.** The base alloy is suitable; final component compliance depends on manufacturing and heat treatment. | | | **Key Procurement Specification** | **Sandvik Material Data Sheet 2059 (SANMAC 2205)** and a **detailed drawing specifying Hollow Bar dimensions**. | It is **imperative** to specify **"SANMAC"** to receive the machinability-enhanced product. | --- ## **Critical Technical & Procurement Note** **SANMAC Hollow Bar is a value-engineered product where the premium is justified by dramatically lower machining costs.** 1. **Mandatory Specification:** You **must** specify **"Sandvik SANMAC SAF 2205 Hollow Bar"** to access the machinability benefits. "SAF 2205 Hollow Bar" alone will yield the standard grade. 2. **Technical Collaboration:** Engage with Sandvik technical support to obtain **optimized machining parameters** (speeds, feeds, tool geometries) specifically for SANMAC 2205. Using this data is key to maximizing productivity. 3. **Total Cost Analysis:** Evaluate based on **total cost per finished part** (material + machining + tooling). The higher material cost of SANMAC is typically offset multiple times over by savings in machining time, tool consumption, and scrap reduction. 4. **Certification:** Require a **Sandvik Certificate of Conformity** that includes standard chemical/mechanical data **and explicitly confirms the "SANMAC" quality grade**. Dimensional inspection reports should also be provided. 5. **Optimal Use Case:** This product delivers the greatest economic benefit in **high-volume production runs of complex, hollow parts** on CNC lathes and machining centers where machining is the primary cost driver. -:- For detailed product information, please contact sales. -: Sandvik SANMAC SAF 2205 Hollow Bar Specification Dimensions Size： Diameter 20-1000 mm Length <7296 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 Hollow Bar Properties -:- For detailed product information, please contact sales. -:
