Marthinus you are correct. The PSF 27 material is made via the Ospray "now called Danspray" process. PM and Danspray start the same way with an atomizer making powder. PM lets the powder fall and solidify. The powder is then placed into a can as loose powder then consolidated into an ingot by Hot Isostatic Pressing. In Danspray, the powder is directed toward a rotating platen and the ingot is built up during atomization. Danspray will have a PM structure that contains slightly larger carbides than PM produced via HIPing.
