SS-PREP® MAR M247Prealloy Spherical Powder

SS-PREP® MAR M247Prealloy 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, 304, 17-4PH, 18Ni300…), Duplex Steel, High-nitrogen Steel, and Aluminum.

Currently, Sino-Euro has prepared MAR M247prealloy spherical powder. Fig. 1 displays the properties and chemistry of MAR M247powder. As for 50-100μm powder, Hall flow speed with 2.5mm calibrated orifice is 13.5s/50g, and apparent density is 5.17g/cm³.

Powder morphology is shown as below.

Mar M247 is a material which is creep and hot corrosion resistance and also has excellent castability, high temperature properties. In the past few decades, Mar-M247 alloy has gradually replaced IN713LC alloy and is widely used to manufacture aeroengine and heavy gas turbine components whose operating temperatures is around 1000 °C.
