Small Can Powder: Ultra-Fine 316L Stainless Steel Explorer
“Small‑can powder” is an ultrafine 316L stainless steel powder specially developed by TIJO for scientific research and the development of novel applications. It is produced using vacuum atomization combined with precision classification, yielding a D50 of approximately 3 μm and a tightly controlled particle size distribution (D10 ≈ 1.4 μm, D90 ≈ 6.3 μm). The powder exhibits a high specific surface area, excellent sintering activity, and superior flowability. Its chemical composition complies with the 316L stainless steel standard (Cr 16.49%, Ni 10.72%, Mo 2.19%), and its oxygen content is as low as 0.163%, ensuring consistent material performance. This ultrafine powder offers a new material option for metal injection molding (MIM), fine powder metallurgy, catalyst supports, cold spraying, conductive pastes, 3D printing, and other fields. Owing to the unique properties of this ultrafine powder, we look forward to collaborating with our customers to explore additional innovative applications. Each batch is accompanied by a Certificate of Analysis (COA) and is eligible for third‑party testing.
Each batch is accompanied by a Certificate of Analysis (COA) reporting composition, particle size, oxygen content, and bulk/ tapped density; batch number TJSAY001 is traceable.
This product is designed for exploratory applications. Customers are welcome to request free samples and jointly pioneer new frontiers in ultrafine stainless steel powder.
