Sandvik Osprey 1.2709 Tool Steel Powder Product Information -:- For detailed product information, please contact sales. -: # **Sandvik Osprey™ 1.2709 (18Ni300) Maraging Steel Powder | Premium Gas-Atomized Maraging Steel for Additive Manufacturing** ## **Overview** Sandvik Osprey™ 1.2709 is a high-performance, gas-atomized maraging steel powder optimized for Additive Manufacturing (AM) processes, based on the widely recognized 1.2709 (18Ni300) maraging steel grade. This powder leverages Sandvik's proprietary gas atomization technology to deliver exceptional powder quality with **high sphericity, consistent particle size distribution, low oxygen content, and excellent flowability**. 1.2709 belongs to the family of low-carbon, iron-nickel maraging steels, renowned for their unique combination of ultra-high strength, toughness, and dimensional stability after a simple aging heat treatment. Specifically engineered for Laser Powder Bed Fusion (L-PBF) and Direct Energy Deposition (DED), Osprey™ 1.2709 enables the production of complex, high-performance components for demanding tooling, aerospace, and industrial applications, often achieving mechanical properties superior to conventional counterparts. ## **Key Features:** * **Optimized for AM:** Chemistry and powder morphology are fine-tuned for superior processability in L-PBF and DED systems. * **Exceptional Powder Quality:** High sphericity (>95%), controlled particle size distribution (15-53 µm typical), minimal satellites, and excellent flowability ensure consistent, high-density builds. * **Superior As-Built Properties:** Achieves high strength and good toughness directly after printing, requiring only a simple aging treatment to reach peak performance. * **Minimal Distortion:** Undergoes negligible dimensional change (<0.1%) during the low-temperature aging process, critical for precision components. * **Excellent Weldability & Processability:** Ultra-low carbon content (<0.03%) significantly reduces hot cracking susceptibility during AM. * **Simple Heat Treatment:** Hardening is achieved through a single-step aging process (typically 480-500°C for 3-8 hours), eliminating complex quenching. * **High Recyclability:** Powder maintains consistent chemical and physical properties over multiple reuse cycles with proper handling. * **Outstanding Fatigue Resistance:** Excellent performance under cyclic loading conditions, especially in high-cycle fatigue regimes. --- ## **Material Specifications: Osprey™ 1.2709 (18Ni300)** ### **1.
