📋 Tender Overview
Sandvik has ventured where no other company has gone it has successfully 3D-printed components in super-duplex stainless steel. The innovation opens up exciting opportunities for offshore industrial segments.The use of iron-based and highly corrosion-resistant materials in additive manufacturing AM has seen significant growth in interest during the past few years. This is largely due to the needs of demanding industries such as the offshore and marine segments where challenging environments call not only for advanced materials but also for on-demand production of spare parts to minimize stock and reduce material waste.In terms of withstanding harsh elements there is one material family that stands out. Osprey 2507 is a super-duplex alloy with excellent corrosion resistance and outstanding mechanical strength produced and optimized for 3D printing by the leading materials experts at Sandvik Additive Manufacturing. For decades Sandvik has been leading the materials evolution for duplex stainless steels continually launching new duplex and super-duplex materials with improved properties. The offering became even stronger in 2019 when Sandvik acquired a significant stake in the BEAMIT Group the worlds largest independent AM service provider. The BEAMIT Group supports the most demanding industries with high-end metal components.First to marketSandvik super-duplex stainless steels are already successfully used in highly corrosive environments such as the seawater-exposed offshore energy sector and in demanding chemical processing. Predominantly used in the shape of seamless tubes plates and bars super-duplex steel has proved a challenge in additive manufacturing. The complexity with two different phases in super duplex austenite and ferrite makes it difficult to 3D-print without cracks. In addition the heat treatment must be controlled afterward to obtain a 5050 percent microstructure.We are proud to say that Sandvik is the first to offer 3D-printed super-duplex components to the market says Mikael Schuisky VP and Business Unit Manager at Sandvik Additive Manufacturing. While many have tried and failed we are very pleased to have seen components printed to a standard that doesnt just meet but also outperforms that of several conventionally manufactured counterparts.Secret to successNikhil Dixit is an Application Engineer at Sandvik Additive Manufacturing . He has been heavily involved with the development of process parameters and material qualifications for the 3D printing of super-duplex stainless steels.
