Sandvik SANMAC SAF 2205 Billet Product Information -:- For detailed product information, please contact sales. -: # **Product Name: Sandvik SANMAC SAF 2205 Billet (UNS S32205 / EN 1.4462)** ## **Introduction** Sandvik SANMAC SAF 2205 Billet is a premium-grade, semi-finished product specifically engineered as the optimal feedstock for manufacturing **high-volume, precision-machined components**. Distinguished from standard billets, the **SANMAC** designation signifies a proprietary production process that tailors the microstructure and inclusion morphology to deliver **superior machinability** without compromising the fundamental corrosion resistance or mechanical strength of the SAF 2205 duplex alloy. This billet is the ideal starting material for manufacturers of complex parts like pump shafts, valve trim, and fittings, where **cost-effective, high-speed machining and extended tool life are critical to production economics**. ## **Key Features** * **Engineered for Superior Machinability:** The SANMAC process controls the type, size, and distribution of inclusions, leading to **improved chip breakability, reduced cutting forces, extended tool life, and excellent surface finish**. This can boost machining productivity by 20-50% compared to standard duplex billets. * **Maintains Full Duplex Performance:** Guarantees the full chemical and mechanical property profile of premium UNS S32205, including high strength (yield ≥500 MPa) and excellent resistance to chloride stress corrosion cracking and pitting (PREN ≥ 34). * **Exceptional Consistency and Homogeneity:** Provides uniform microstructure and predictable machining behavior across the entire billet length and cross-section, which is vital for automated, high-volume production runs. * **Cost-Efficiency in Finished Part Production:** The reduction in machining time, tooling costs, and scrap rates directly translates to a lower total cost per finished component. --- ## **1. Chemical Composition (Typical Weight % - Sandvik SANMAC Specification)** The chemistry adheres to the strict UNS S32205 specification, with additional controls for elements affecting machinability. | 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-Enhancing Features:** While maintaining the standard, Sandvik's process for SANMAC optimizes the **sulfide inclusion morphology** (typically calcium-treated) to act as chip breakers during machining, a key differentiator from standard billets. **PREN Calculation:** PREN = %Cr + 3.3(%Mo) + 16(%N) ≥ **34** --- ## **2. Physical & Mechanical Properties (Post-Forging/Bar Rolling & Heat Treatment)** *Final properties are achieved after the billet is processed into bar stock and undergoes final solution annealing. The billet itself is supplied in a hot-worked (e.g., rolled) condition suitable for further processing.* | Property (In Final Bar, After 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** | | **Machinability Index (Comparative)** | **~60%** (vs. 100% for 1215 free-machining steel). **Significantly higher than standard 2205 billets.** | --- ## **3. Product Forms & Downstream Applications** **Billet Form & Typical Journey:** 1. **SANMAC Billet:** Hot-rolled, conditioned (ground) rounds or squares. 2. **Processing:** Billet is further hot-rolled or extruded into **bar stock** (rounds, hexes) or wire rod. 3. **Final Product:** The bar stock is then solution annealed, pickled, and straightened, ready for sale as **Sandvik SANMAC 2205 Bar** to machine shops. **Primary Target Applications (High-Volume Machined Parts):** This billet is destined to become bar stock for manufacturing precision components where machining is the primary shaping operation: * **Pump & Valve Components:** Shafts, stems, sleeves, bushings, impellers, valve plugs, and seats for chemical, oil & gas, and marine industries. * **Fasteners:** High-strength bolts, studs, nuts, and threaded rods for corrosive service applications. * **Fittings & Connectors:** Machined socket weld fittings, unions, and adaptors. * **Automated Lathe Parts:** Components produced on CNC lathes and multi-spindle automatics where predictable chip control is essential. --- ## **4. International Standards & Approvals** The final bar product derived from SANMAC billet meets all standard certifications, with the added value of proven machinability. | Standard Type | Standard Number & Designation | Notes | | :------------------ | :--------------------------------------------------------------------------------------------------------------------------- | :-------------------------------------------------------------------- | | **Unified Numbering System (UNS)** | **S32205** | The premium duplex 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 final bar product is certified to this standard. | | **NACE MR0175/ISO 15156** | **Enabling Compliance.** The base material meets sour service requirements; final compliance depends on component manufacturing and heat treatment. | | | **Key Procurement Specification** | **Sandvik Material Data Sheet 2059 (SANMAC 2205)** and/or a specific **Technical Agreement for SANMAC Billet**. | This is critical. The "SANMAC" designation and its associated machinability guarantees are proprietary to Sandvik and must be explicitly specified. | --- ## **Critical Technical & Procurement Note** **SANMAC is a value-added product line focused on manufacturing efficiency. Distinguish it from standard forging billets.** 1. **Procurement Specification:** To access the machinability benefits, you **must** specify **"Sandvik SANMAC SAF 2205 Billet"** explicitly. Ordering generic "SAF 2205 Billet" will yield standard material. 2. **Intended Use:** This billet is **primarily for rolling into bar stock for machining**, not for large, complex open-die forgings. Its value is realized in high-volume turning, milling, and drilling operations. 3. **Machining Data:** Sandvik provides optimized machining parameters (speeds, feeds, tool geometries) for SANMAC grades. Utilizing this data is key to unlocking the full productivity gain. 4. **Certification:** Require a **Sandvik Certificate of Conformity** that includes the standard chemical/mechanical data **and** a confirmation of the **SANMAC quality level**. Traceability from billet to final bar stock is maintained. 5. **Economic Justification:** The cost premium for SANMAC billet is justified by significantly lower machining costs per part. A total cost analysis (material + machining) typically shows a clear advantage for SANMAC in production machining. -:- For detailed product information, please contact sales. -: Sandvik SANMAC SAF 2205 Billet Specification Dimensions Size： Diameter 20-1000 mm Length <7294 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 Billet Properties -:- For detailed product information, please contact sales. -:
