Nickel-based superalloys for additive manufacturing
Sandvik is now adding nickel-based superalloys to its word-leading Osprey® metal powder program, produced in our state-of-the-art atomizing plant with melting under vacuum. The powder can be used for near-net-shape technologies like Additive Manufacturing (AM) or Hot Isostatic Pressing (HIP).
Contact usBased on Sandvik’s 150-year material knowledge and in-house powder manufacturing and R&D capabilities, we are experts at matching material to any application. We offer the widest range of alloys around and can even customize materials.
In addition, Sandvik also has all relevant Additive Manufacturing processes for metals in-house, which means that we can adapt the powder to any printing process.
Nickel-based superalloys
Nickel-based alloys are typically used in applications like jet turbines, gas turbines, oil and gas, pressure vessels or chemical processing components. We can offer Alloy 625, Alloy 718 and H-X. Other alloys are also available on request.
Due to Sandvik’s vacuum induction melting process, our powders offer significantly lower oxygen and nitrogen levels than conventional metallurgy, typically below 250 ppm. Lower levels of O and N can be offered but needs to be discussed related to the type of Ni-based alloy.
Below you find more information about and typical material properties of Osprey® Alloy 718 and Osprey® Alloy 625, melted under vacuum.
