Abstract:
Outokumpu, stainless steel producer, started producing spherical metal powders in a Vacuum Induction melting inert Gas Atomization (VIGA) plant in Krefeld Germany at the beginning of 2023. Using flat scrap arising from its own processes as raw material the company can produce gas atomized powders. The produced metal powders are high quality, customizable and sustainable raw materials for production in various Powder Metallurgy (PM) technologies. To showcase the importance of broadening the possibilities of material selection for PM engineers in the present article two examples of novel stainless steel powder materials barely used nowadays are introduced. The first one a stainless-steel alloy used for elevated temperatures 253MA (1.4835). This powder grade was developed at pilot scale in collaboration with Swerim Metal Research Institute. The second one a highly alloyed stainless-steel grade also known as a super austenitic stainless steel 904L (1.4539). This powder grade was developed at pilot scale in collaboration with RWTH Aachen University.
