SS-PREP® GH3230 Prealloy Spherical Powder

SS-PREP® GH3230 Prealloy Spherical Powder

GH3230 alloy (Similar to Haynes230) is a solid solution strengthening superalloy with W and Mo as the main strengthening elements.

• Operating temperature ranges from 700℃ to 1050℃

• High strength, good thermal stability and oxidation resistance

• Widely used for combustion chamber components for advanced aero engines

Sino-Euro has recently developed SS-PREP® GH3230 prealloy spherical powder. Fig. 1 displays the properties and chemistry of GH3230 powder. Hall flow speed with 2.5mm calibrated orifice is 12.0s/50g. Tap density is 5.22g/cm³. Fig. 2 show the powder morphology.

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.
