SUS316L

316L stainless steel alloy powder is an iron-based alloy powder containing Cr, Ni, Mo, and ultra-low C. The 316L stainless steel alloy powder prepared under atomization conditions has low oxygen content (typically≤ 500ppm), high sphericity, excellent flowability and apparent density, low porosity, high density, and excellent corrosion resistance, making it a core material in high-end manufacturing fields such as 3D printing and additive manufacturing.
