Sandvik Osprey D2 Tool Steel Powder (Grade 80% - 22) Product Information -:- For detailed product information, please contact sales. -: # **Sandvik Osprey® D2 Tool Steel Powder (Grade 80% - 22 µm)** ## **Product Overview** Sandvik Osprey® D2 (Grade 80% - 22 µm) is a gas-atomized, pre-alloyed metal powder specifically engineered for **Additive Manufacturing (AM)** and **Metal Injection Molding (MIM)** processes. It reproduces the chemistry of the classic AISI D2 cold work tool steel in a spherical powder form, offering exceptional flowability, high packing density, and consistent particle size distribution. This powder enables the production of complex, high-performance tooling components with superior wear resistance, high hardness, and good dimensional stability directly from digital designs, bypassing many limitations of conventional machining. ## **Key Features & Benefits** * **High-Quality Powder Morphology:** Produced via inert gas atomization, the powder features highly spherical particles with minimal satellites, ensuring excellent flowability essential for consistent layer spreading in Powder Bed Fusion (PBF) processes like Laser Beam Powder Bed Fusion (LB-PBF) and high feedstock loading in MIM. * **Tailored for AM/MIM:** The powder chemistry and particle characteristics (size distribution, morphology) are optimized for processing in AM and MIM, leading to high-density, high-integrity as-built parts. * **Inherited D2 Properties:** After appropriate post-processing heat treatment, components achieve the renowned properties of wrought D2 steel: exceptional wear resistance due to high primary carbide volume, good compressive strength, and moderate toughness. * **Design Freedom & Tooling Optimization:** Enables the manufacture of conformal cooling channels in injection molds, lightweight lattice structures, and complex geometries that are impossible or prohibitively expensive to produce with conventional methods, leading to improved tool performance and productivity. * **Material Consistency:** Tight control over particle size distribution (PSD) and chemical composition ensures batch-to-bust reproducibility, critical for industrial production. ## **International Standards & Designations** This powder is designed to yield components meeting the specifications of conventional D2 tool steel after proper sintering (MIM) or building and heat treatment (AM). | Material System | Standard Designation | Comparable Standards for Final Properties | | :--- | :--- | :--- | | **Sandvik Osprey®** | **D2 Powder (80% < 22 µm)** | **AISI: D2 | EUR (EN): 1.2379 | JIS: SKD11** | | **Particle Naming** | **Grade 80% - 22** | Indicates **80% of particles are below 22 micrometers** (typical D50 ~15-18 µm). | **Note:** "80% - 22" is a key powder specification indicating a fine powder cut suitable for most laser-based PBF systems and MIM. "Osprey®" is a registered trademark of Sandvik. ## **Chemical Composition (Typical - % by weight)** The composition is tailored to match standard D2 while considering AM processability. | Element | Content (%) | Role | | :--- | :--- | :--- | | **Carbon (C)** | 1.50 - 1.60 | Forms hard chromium carbides for wear resistance; provides matrix hardness. | | **Chromium (Cr)** | 11.0 - 12.0 | Primary carbide former (M₇C₃); provides corrosion/oxidation resistance. | | **Molybdenum (Mo)** | 0.70 - 0.90 | Enhances hardenability, refines grain, improves toughness and tempering resistance. | | **Vanadium (V)** | 0.90 - 1.10 | Forms hard, fine MC carbides; inhibits grain growth, increases wear resistance. | | **Silicon (Si)** | 0.10 - 0.40 | Deoxidizer, solid solution strengthener. | | **Manganese (Mn)** | 0.20 - 0.40 | Aids hardenability, combats sulfur embrittlement. | | **Sulfur (S)** | ≤ 0.010 | Very low to ensure good toughness and polishability. | | **Phosphorus (P)** | ≤ 0.020 | Very low to ensure good toughness. | | **Oxygen (O)** | < 100 ppm | Tightly controlled to minimize oxide inclusions in final part. | | **Iron (Fe)** | Balance | | ## **Powder Characteristics & Physical Properties** * **Particle Size Distribution (PSD):** **D10: ~8 µm | D50: ~15-18 µm | D90: ~25-30 µm** (80% < 22 µm). * **Particle Morphology:** Highly spherical. * **Apparent Density:** ~4.2 - 4.5 g/cm³. * **Tap Density:** ~4.8 - 5.1 g/cm³. * **Flowability (Hall Flowmeter):** Typically < 25 s/50g (Excellent). * **Satellite Content:** Low. ## **Final Part Mechanical Properties (After AM Build & Heat Treatment)** Properties are highly dependent on the AM process parameters (e.g., laser power, scan speed) and the specific heat treatment cycle. The following are achievable targets for a fully dense LB-PBF part after proper hardening and tempering. * **As-Built Hardness:** Typically 50-55 HRC (contains retained austenite). * **Hardened & Tempered Hardness:** **58 - 62 HRC** (Standard for D2; double tempering at 520-540°C is common). * **Ultimate Tensile Strength (UTS):** ~1900 - 2200 MPa. * **Yield Strength (Rp0.2):** ~1600 - 1900 MPa. * **Elongation at Break:** ~1 - 3% (Brittle material class). * **Impact Toughness:** Lower than wrought D2 due to inherent AM microstructure; typically in the range of 5-15 J (Charpy unnotched). * **Relative Density (as-built):** > 99.5% achievable with optimized parameters. * **Wear Resistance:** Excellent, comparable to wrought D2, due to high volume fraction of hard carbides. ## **Typical Applications** This powder is used to manufacture advanced tooling and wear parts via AM and MIM: * **AM for Tooling:** * **Plastic Injection Molds:** Core and cavity inserts with **conformal cooling channels** for reduced cycle times and warpage. * **Stamping, Blanking, and Forming Dies:** Complex die inserts, punches, and wear plates. * **Cutting Tools & Knives:** Specialized cutting inserts and blades with complex geometries. * **Metal Injection Molding (MIM):** * **Small, Complex Wear Parts:** Surgical instrument components, watch parts, firearm components, precision gears, and industrial cutting inserts. * **Other AM Processes:** Suitable for Directed Energy Deposition (DED) for repair or coating of existing D2 tooling. ## **Processing Considerations** * **AM (LB-PBF) Processing:** Requires high laser energy density. Preheating the build plate (200-400°C) is highly recommended to reduce residual stresses and cracking risk. Process in an inert atmosphere (Argon or Nitrogen) with low oxygen content (< 1000 ppm). * **Heat Treatment:** **Critical for performance.** Standard D2 heat treatment cycles apply: Preheating (~800°C), Austenitizing (1020-1050°C), quenching (forced air or gas), and **Double/Triple Tempering** (500-540°C). Stress relieving (600-650°C) before rough machining is advised. * **Machining & Finishing:** Best machined in the soft annealed or stress-relieved state. Final machining after hardening is difficult (grinding/EDM only). AM surfaces may require machining, polishing, or abrasive flow finishing for mold applications. * **Support Structures:** Required in AM due to high hardness and cracking tendency; design for easy removal. ## **Summary** **Sandvik Osprey® D2 Powder (80% - 22 µm)** bridges the gap between a classic, high-performance tool steel and the transformative capabilities of additive manufacturing. By providing a high-quality, consistent feedstock, it allows for the production of next-generation tooling with internal complexity and optimized thermal management that dramatically improves productivity. While final parts require careful heat treatment to achieve optimal properties, this material unlocks new design paradigms for durable, wear-resistant components in demanding industrial applications. -:- For detailed product information, please contact sales. -: Sandvik Osprey D2 Tool Steel Powder (Grade 80% - 22) Specification Dimensions Size： Diameter 20-1000 mm Length <5247 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 Osprey D2 Tool Steel Powder (Grade 80% - 22) Properties -:- For detailed product information, please contact sales. -:
