Sandvik Group pioneers super-duplex stainless steel 3D printing

The Sandvik Group, a global leader in advanced materials and additive manufacturing, has achieved a significant milestone by successfully 3D printing with a super-duplex stainless steel alloy. This advanced material, known as Osprey 2507, is being printed using Sandvik's proprietary powder bed fusion technology.

Super-duplex stainless steels offer a unique combination of high strength, excellent corrosion resistance, and good weldability. These properties make them highly desirable for demanding applications in industries such as oil and gas, chemical processing, and marine engineering. Historically, the complex metallurgy of these alloys has presented challenges for traditional manufacturing methods, making them difficult to process and form.

Sandvik's achievement in 3D printing this material opens up new possibilities for creating intricate and customized components that were previously unfeasible. The additive manufacturing process allows for the layer-by-layer construction of parts, enabling complex geometries and internal structures without the limitations of subtractive manufacturing.

The company has been actively involved in developing advanced metal powders for additive manufacturing. Their expertise in powder metallurgy, combined with their 3D printing capabilities, positions them at the forefront of innovation in this field. The successful printing of Osprey 2507 represents a significant step forward in expanding the range of high-performance materials available for additive manufacturing.
