Product description
Osprey® 2205 is a duplex (austenitic-ferritic) stainless steel characterized by high resistance to stress corrosion cracking (SCC), pitting, crevice and general corrosion and very high mechanical strength.
Main characteristics of Osprey® 2205
- High resistance to stress corrosion cracking (SCC) in chloride-bearing environments and in environments containing hydrogen sulfide
- High resistance to general corrosion, pitting, crevice corrosion, erosion and corrosion fatigue
- High mechanical strength – roughly twice the proof strength of austenitic stainless steel
- Good weldability
This metal powder is manufactured by Inert Gas Atomization (IGA), producing a powder with a spherical morphology which provides good flow characteristics and high packing density. In addition, the powder has a low oxygen content and low impurity levels, resulting in a metallurgically clean product with enhanced mechanical performance.

Powder for Additive Manufacturing
Osprey® metal powder for Additive Manufacturing is characterized by a spherical morphology and high packing density, which confer good flow properties. For powder bed processes these are essential when applying fresh powder layers to the bed to ensure uniform and consistent part build.
For blown powder processes, such as Direct Energy Deposition (DED), good flow ensures uniform build rates. Tight control of the particle size distribution also helps ensure good flowability. Low oxygen powders result in clean microstructures and low inclusion levels in the finished parts.
