Water Atomized
AISI 304 Stainless Steel Powder is a finely divided austenitic stainless steel form, combining corrosion resistance, high ductility, and excellent oxidation stability with the versatility of powder metallurgy processing. Its particle morphology and size distribution allow precise control over densification, surface area, and flowability, making it ideal for additive manufacturing, thermal spraying, and powder compaction. Industries such as aerospace, chemical processing, biomedical engineering, and advanced tooling use it for producing intricate near-net-shape components, corrosion-resistant coatings, and high-performance sintered parts. Specific applications include selective laser melting of complex structural parts, thermal spray coatings for chemical plant equipment, and powder-compacted filters with superior corrosion stability. In research, 304 stainless steel powder enables studies on microstructure evolution, surface engineering, and hybrid material development, supporting innovations in both manufacturing technology and material performance optimization. Its adaptability across forming methods and high stability in aggressive environments ensures it remains a critical feedstock in industrial production and experimental fabrication.
