Sandvik Osprey 18Ni300 Tool Steel Powder Product Information -:- For detailed product information, please contact sales. -: # **Sandvik Osprey™ 18Ni300 Maraging Steel Powder | Premium Gas-Atomized Maraging Steel for Additive Manufacturing** ## **Overview** Sandvik Osprey™ 18Ni300 is a high-performance, gas-atomized maraging steel powder specifically engineered for additive manufacturing (AM) processes, particularly Laser Powder Bed Fusion (L-PBF) and Direct Energy Deposition (DED). This powder is based on the renowned 18Ni300 (1.2709) maraging steel grade, optimized through Sandvik's advanced atomization technology to deliver exceptional **as-built mechanical properties, minimal porosity, and excellent processability** in AM systems. Maraging steels are characterized by their unique combination of ultra-high strength and toughness, achieved through a low-carbon iron-nickel matrix strengthened by intermetallic precipitation during aging. Osprey™ 18Ni300 enables the production of complex, high-performance tooling, aerospace, and industrial components with mechanical properties often exceeding those of traditionally manufactured counterparts. ## **Key Features:** - **Superior As-Built Properties:** High strength and toughness directly after printing, without traditional quenching - **Minimal Distortion:** Extremely low dimensional change during age hardening (<0.1%) - **Excellent Weldability/Processability:** Minimal cracking tendency in AM due to low carbon content - **Outstanding Powder Characteristics:** High sphericity, controlled size distribution, excellent flowability - **Simple Heat Treatment:** Single-step aging process (480-500°C) for full hardening - **Excellent Machinability:** In both as-built and solution annealed conditions - **Superior Fatigue Resistance:** Particularly in high-cycle fatigue applications - **Good Corrosion Resistance:** Comparable to conventional maraging steels - **High Recyclability:** Consistent properties over multiple reuse cycles --- ## **Material Specifications: Osprey™ 18Ni300** ### **1.
