Additive manufacturing powders require controlled chemistry, purity, particle size, and flowability. Steel and alloy powders are certified, traceable, and quality‑checked to ensure stable processing, consistent microstructure, and reliable component performance.
Powders for Additive Manufacturing are critical raw materials that directly determine process stability, part quality, and mechanical performance of additively manufactured components. Material requirements are highly demanding, as powders must ensure consistent layer deposition, stable melting or sintering behavior, and reproducible microstructures. Key parameters include controlled chemical composition, high purity, low oxygen and moisture content, and minimal contamination. Powder morphology is equally important: high sphericity, smooth surface condition, and a narrow particle size distribution are essential for good flowability and uniform packing density. Steel and alloy powders commonly used include stainless steels, maraging steels, tool steels, low‑alloy steels, and nickel‑based alloys. These materials are selected for their strength, fatigue resistance, corrosion resistance, and suitability for post‑processing heat treatments. Quality features focus on certified powder production, batch‑to‑batch consistency, full traceability, and controlled powder handling and reuse. Comprehensive powder characterization, process qualification, and incoming inspection ensure reliable performance and compliance with demanding industrial and aerospace standards.
