Osprey® 2507 components outperforming several traditional counterparts

With industries such asoffshore- and marine that increasingly require on-demand production of spare parts, a better management of supply chain and a decrease in material waste, material producers such as Sandvik have their part to play to address this range of challenges by delivering dedicated materials.

With that in mind, and given the increasing use of iron-based and highly corrosion resistant materials in additive manufacturing (AM), Sandvik and part subsidiary BEAMIT Grouphave worked together on the development of a new metal powder. Named Osprey® 2507, the new metal powder would deliver “a unique capability to additively manufacture components in super-duplex stainless steel”.  

According to Sandvik, 3D printed parts produced with this material would be near fully dense (>99.9%) and crack-free, even before post processing.

 “While many have tried and failed, we are very pleased to have seen components printed to a standard that doesn’t just meet, but outperform that of several conventionally manufactured counterparts”, Mikael Schuisky, VP and Business Unit Manager at Sandvik Additive Manufacturing.  

Developed at Sandvik Additive Manufacturing, the materials team explains Osprey® 2507 is a super duplex alloy that has excellent corrosion resistance and outstanding mechanical strength.

The company is no stranger to the duplex stainless steels market as during the past decade, it has been continuously providing the market with their improved properties.

With successful trials inhighly corrosive environments such as the seawater exposed offshore energy sector, Sandvik’s super-duplex stainless steels would meet the production requirements of seamless tubes, plates, and bars, super-duplex steel, applications that have often been challenging for AM.

A tangible application the company unveils with this material is an “impeller reinvented” – a lighter, faster, and more efficiently manufactured offshore essential, developed in collaboration with energy giant Equinor andNorwegian Eureka Pumps.

We are very excited to co-launch this potent combination of a superior material and the disruptive benefits of additive manufacturing to the market”, says Michele Antolotti, Engineering and R&D Manager at the BEAMIT Group. “Having already developed print parameters for single-laser machines, we are now progressing to expand our joint offering to include even larger applications. With the profound materials expertise within Sandvik, and BEAMIT Group’s market-leading abilities throughout the additive value chain, we are truly in a unique position to supply the offshore industries with an array of business-critical benefits, in terms of component performance and timely production alike.”

With the release of this super-duplex stainless steel material, Sandvik has added a solid string to its bow, a string that will enable it to perfectly strengthen its “Plan it, Print it, Perfect it” approach, which states that 3D printing is just one of the seven steps one needs to master to succeed in the industrialization of AM.
