Outokumpu, a stainless steel manufacturer, is expanding its metal powder production for additive manufacturing into the aerospace sector. The company will deliver a new stainless steel powder grade for 3D printing applications in May 2025. This production focuses on a jointly engineered heat exchange component for aerospace use, pending prototype validation.
“Outokumpu is committed to accelerating circular business models for high tech stainless steel applications,” says Marten Franz, Head of Metal Powder Business at Outokumpu. “Our go-to-market strategy is to innovate product designs for complex, high performance geometries for niche applications.”
The new spherical stainless steel powder contains specific alloy additives to create a high-performance austenitic material. It serves as an alternative to nickel-based alloys in demanding 3D printed applications. The product aims to meet customer needs for components produced in small quantities with shorter development cycles.
Beyond aerospace applications, Outokumpu is developing powder grades for other industries. The company is working on medical-grade powder specifications for health-tech applications, focusing on nickel-free materials that could also be used in jewelry. Additional development includes heat-resistant alloys for additively manufactured components like turbines and power plant components.
Outokumpu entered the metal powder market for additive manufacturing in 2023. The company’s strategy centers on producing specialty metal powders not currently available in the market. Outokumpu collaborates with 3D printing engineering partners to create end products according to customer specifications.
