Sandvik SAF 2205 Billet Product Information -:- For detailed product information, please contact sales. -: # **Product Name: Sandvik SAF 2205 Billet (UNS S32205 / EN 1.4462)** ## **Introduction** Sandvik SAF 2205 Billet is a premium-quality, semi-finished product that serves as the foundational raw material for manufacturing high-performance, corrosion-resistant components through forging, extrusion, or further rolling processes. As the starting stock of the renowned SAF 2205 duplex stainless steel, this billet guarantees a **homogeneous, segregated-free, and inclusion-controlled microstructure**. It is specifically produced to meet the stringent demands of **forge masters, ring roller manufacturers, and producers of seamless pipes and large bars**, ensuring the final forged or wrought products inherit the alloy's exceptional combination of high strength and superior corrosion resistance. ## **Key Features** * **Exceptional Internal Soundness:** Produced using advanced melting and refining processes (such as AOD/VOD) to achieve very low levels of impurities, inclusions, and segregation, ensuring structural integrity in large, high-load components. * **Consistent & Homogeneous Microstructure:** Guarantees a uniform and balanced ferrite-austenite phase structure throughout the cross-section, which is critical for predictable mechanical properties and corrosion resistance after forging. * **Optimized Forgeability:** Controlled chemical composition and a clean microstructure contribute to excellent hot workability, allowing for efficient forging, piercing, and extrusion operations. * **Full Traceability & Certification:** Each billet lot is fully traceable with complete metallurgical certification, providing confidence for critical applications in oil & gas, chemical, and marine industries. --- ## **1. Chemical Composition (Typical Weight % - Sandvik Specification)** The billet chemistry is tightly controlled to the premium UNS S32205 specification, ensuring optimal performance in the final forged product. | 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** | | | **Premium Billet Quality:** Sandvik's billet guarantees the higher minimum Molybdenum (≥3.0%) and Nitrogen (≥0.14%) content of UNS S32205, ensuring the final product's PREN ≥ 34. **PREN Calculation:** PREN = %Cr + 3.3(%Mo) + 16(%N) ≥ **34** --- ## **2. Physical & Mechanical Properties (Post-Forging & Heat Treatment)** *Properties are developed in the final component after hot working and a mandatory solution annealing heat treatment.* | Property (After Final Heat Treatment) | Typical Value / Range | | :-------------------------------------------- | :------------------------------ | | Density | 7.80 g/cm³ | | **Tensile Strength (Rm)** | **700 - 900 MPa** | | **Yield Strength (Rp0.2)** | **≥ 500 MPa** | | **Elongation (A)** | **≥ 25 %** | | Hardness (Brinell) | 240 - 300 HBW | | **Impact Toughness (Charpy V-notch, min.)** | **≥ 100 J at -40°C** | **Billet-Specific Properties:** * **Surface Quality:** Conditioned (ground) to remove surface defects, ensuring a clean starting material for forging. * **Macro-Etch Soundness:** Meets stringent internal and customer-specific standards for center porosity and segregation. --- ## **3. Product Forms & Downstream Applications** **Billet Form:** * **Continuously Cast or Forged Ingot:** Typically square or round cross-section, cut to required length. * **Surface Condition:** Black, ground, or peeled. **Primary Downstream Manufacturing Routes & Final Applications:** The billet is the starting point for critical, heavy-duty components: 1. **Open-Die / Closed-Die Forging:** Produces large, complex parts. * **Applications:** Large pump casings, valve bodies, pressure vessel nozzles, forged flanges (ASTM A182 F51), fittings, and large shafts. 2. **Ring Rolling:** Produces seamless rings for bearing races, gear blanks, and high-pressure housings. 3. **Seamless Pipe & Tube Extrusion/Piercing:** Used to create hollows for seamless pipes (ASTM A790) and pressure tubes. 4. **Re-rolling into Large Bar Stock:** For further processing into large-diameter round bars or profiles. **End-Use Industries:** Oil & Gas (Subsea, Sour Service), Chemical Processing, Power Generation (FGD), Marine, and Desalination. --- ## **4. International Standards & Approvals** The billet is produced to meet the requirements of international standards for the finished wrought product. | Standard Type | Standard Number & Designation | Notes | | :------------------ | :--------------------------------------------------------------------------------------------------------------------------- | :-------------------------------------------------------------------- | | **Unified Numbering System (UNS)** | **S32205** | The premium duplex specification for the final product. | | **EN / EURONORM (Europe)** | **1.4462** | Standard European material number. | | **ASTM (USA)** | **ASTM A276** (Bars), **ASTM A182** (Forgings), **ASTM A790** (Pipe) | The billet is the feedstock to produce final products certifiable to these standards. | | **NACE MR0175/ISO 15156** | **Enabling Compliance.** The billet quality and chemistry are foundational for producing sour-service-qualified finished components. | Final compliance depends on the entire manufacturing and heat treatment chain. | | **Key Procurement Specification** | **Sandvik SAF 2205 Billet Technical Agreement / Data Sheet.** Customer-specific requirements for **ultrasonic testing (UT), macro-etch, and inclusion ratings** are common. | The billet is often procured under a technical agreement detailing stringent quality controls beyond standard mill test certificates. | --- ## **Critical Technical & Procurement Note** **SAF 2205 Billet is an industrial intermediate product requiring further thermomechanical processing.** 1. **Procurement Focus:** Specifications must emphasize **internal quality**: Hydrogen/Oxygen/Nitrogen levels, inclusion control (e.g., ASTM E45), macro-etch soundness, and Ultrasonic Testing (UT) acceptance criteria (e.g., SEP 1921, ASTM A388). 2. **Forging & Heat Treatment:** The billet **must** be hot worked within an appropriate temperature range and subsequently undergo a full **solution annealing heat treatment** (typically 1020-1100°C followed by rapid quench) to develop the correct duplex microstructure, dissolve harmful phases, and achieve the required corrosion resistance and mechanical properties. 3. **Certification:** Require a comprehensive **Sandvik Mill Test Certificate** including full ladle and product analysis, gas content, inclusion rating report, and results of any agreed-upon non-destructive testing (NDT). 4. **Traceability:** Maintain full heat-to-component traceability. The unique melt and billet identification must follow the material through all processing steps. -:- For detailed product information, please contact sales. -: Sandvik SAF 2205 Billet Specification Dimensions Size： Diameter 20-1000 mm Length <7292 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 Billet Properties -:- For detailed product information, please contact sales. -:
