Sandvik and BEAMIT Group (of which Sandvik owns a 30% stake) have introduced the Osprey 2507 super-duplex stainless-steel to the additive manufacturing market, having leaned on its extensive experience in developing similar materials for traditional manufacturing technologies. These materials have been deployed in the manufacture of seawater exposed offshore energy sector components, as well as in chemical processing environments. Now the company is offering the capability to additively manufacture such parts in the Osprey 2507 metal powder.
The material is said to have outstanding mechanical capabilities, with printed parts near fully dense (>99.9%) and crack-free prior to post-processing. These characteristics contribute to the durability of components which will endure harsh conditions. Sandvik has already developed a reinvented impeller in collaboration with Equinor and Norwegian Eureka Pumps using the Osprey 2507 material, while there are various other projects across the marine sector currently on-going.
“We are proud to say Sandvik is the first to offer 3D printed super duplex components to the market,” commented 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 doesn’t just meet but outperform that of several conventionally manufactured counterparts.”
