Tensile properties

Impact strength

Hardness

Typical Vicker’s Hardness levels (ASTM E92, ISO 6507-1, JIS Z2244, GB/T 4340.1), in the L-PBF heat-treated conditions.

Surface roughness

Corrosion properties

Corrosion properties tested on the bulk material as per the following standards.

A suitable heat treatment is carried out on the as-built parts in order to achieve the desired austenitic and ferritic microstructure in the final parts. Typically solution annealing between 1040-1110 °C followed by air or water cooling is performed.

Typical applications areas for Osprey^® 2507 metal powder are components used in, for example, the following industries:

• Oil and gas industry (e.g. impellers, propellers, connecting valves)
• Pulp and paper industry
• Chemical industry
• Refineries and petrochemical plants
• On-shore and off-shore industry
