Outokumpu expands into aerospace with new stainless steel powder

Outokumpu has announced the commercial launch of a new stainless steel metal powder tailored for additive manufacturing (AM) in aerospace and aviation applications. The development marks the company’s latest step in expanding its presence in the metal powder market, following its initial entry in 2023.

The company has delivered its first batch of the new stainless steel powder grade for a specialized 3D-printed heat exchange component designed for the aerospace sector. The component is currently undergoing prototype validation. According to Outokumpu, the powder formulation offers an alternative to nickel-based alloys in demanding manufacturing environments, aiming to support industries that require custom, small-scale component production with rapid development timelines.

“Our approach is to develop stainless steel powder grades that are not yet widely available, with a focus on complex, high-performance geometries for niche applications,” said Marten Franz, Head of Metal Powder Business at Outokumpu. He noted that Outokumpu collaborates closely with additive manufacturing partners to turn powder innovations into functional components that meet specific customer needs.

The new powder, a refined austenitic stainless steel alloy, includes tailored additives to enhance its performance for aerospace use. It is intended to meet the growing demand for advanced materials that combine mechanical strength, corrosion resistance, and suitability for 3D printing technologies.

Diversifying Powder Applications Beyond Aerospace

In addition to aerospace and aviation, Outokumpu is also exploring metal powder applications across a range of industries. The company is developing medical-grade, nickel-free stainless steel powders that could be used in health-tech devices, wearable technologies, and consumer goods such as jewelry. Further research is underway into heat-resistant powder alloys for use in high-temperature components like turbines or parts used in power generation facilities.

Additive manufacturing is increasingly seen as a key enabler of more efficient, sustainable production methods across industries. Outokumpu has identified the technology as a driver for circular business models and plans to foster wider collaboration across sectors to accelerate innovation and sustainability in advanced manufacturing.

The company’s efforts align with broader industrial trends aiming to reduce material waste, shorten supply chains, and improve the performance of critical components through precision engineering enabled by additive manufacturing.
