VDM® Powder 718
VDM® Powder 718 is the powder variant of an age-hardenable nickel-chrome-iron-molybdenum alloy for use in powder based processes such as additive manufacturing, HIP or overlay welding. Hardenability is achieved by specific additions of niobium, titanium and aluminum.

- Features
- VDM® Powder 718 is characterized by:
- Spherical particles with low level of satellites
- High purity and reproducibility level
- Low oxygen content
- Small amount of porosity
- Good flowability
- High apparent and tap density
- Handling
Please note that powder transportation may result in segregation of particle sizes.; Do not open the container in humid environment.; After contact with air the powder has limited storability.; Humidity can influence the powder properties.
- PACKAGING
The whole production and packaging process at VDM Metals is under argon and the powder has no contact to atmos-phere. The standard powder is packed in plastic bags (5kg/10kg/20kg) under argon inside of sealed plastic drums (6l).
- Availability
According to the requirements of the powder based processes, VDM® Powder 718 is available in a wide range of particle fractions from 15 to 250 μm. The typical powder atomization yield ranges from 0,1 to 300 μm. After atomization, the powder is sieved and air classified according to customers specifications. All production and handling operations are carried out under protective atmosphere (argon).; Standard particle fractions; D50 [μm] (tolerance +/-5 μm); The determination of the PSD is done by laser diffraction according to ASTM B822.

Depending on the use conditions, stricter analysis limits apply to certain alloy elements. The purpose of this limitation is to optimize the microstructure and mechanical properties with regard to the intended use. For example, alloys with carbon and niobium concentrations near the upper limit according to ASTM are best suited for high-temperature applications, while lesser carbon and niobium concentrations result in material microstructures that conform better to the requirements of corrosive use conditions.
