SS-PREP® 304 stainless steel Prealloy Spherical Powder
Supreme-Speed Plasma Rotating Electrode Process (SS-PREP®)is the method for producing metal powders where the end of a metal bar is melted while it is rotated about its longitudinal axis. Molten metal is centrifugally ejected and forms droplets that solidify to spherical powder particles. The electrode is melted by non-transfer plasma with over 30000 Revolutions Per Minute (RPM) rotating speed. Causing about 20-50microns thickness of melting area, powders possess better chemical uniformity for every particle. There is no big chemical gap among different particles.
Additionally, high RPM is able to obtain 15-150 microns powder which can be categorized into 15-53μm, 45-106μm, and 45-150μm for SLM, EBM, and DED applications, respectively. Alloy types containsTitanium, Nickel (Inconel 718, Hastelloy X…), Steel (316L, 17-4PH, 18Ni300…), Duplex Steel, High-nitrogen Steel, and Aluminum.
Currently, Sino-Euro has prepared 304 stainless steelprealloy spherical powder. Fig. 1 displays the properties and chemistry of 304 stainless steelpowder. Hall flow speed with 2.5mm calibrated orifice is12.6s/50g, and apparent density is 4.68g/cm3.
