VDM® Powder 718 is the powder variant of an age-hardenable nickel-chrome-iron-molybdenum alloy for use in additive
manufacturing. Hardenability is achieved by means of admixtures of niobium, titanium and aluminum.
VDM® Powder 718 is characterized by:
Low oxygen content
VDM® Powder 718 has an austenitic microstructure where different phases can occur. By means of different heat treatments, graduated mechanical properties of the material can be achieved. The excellent mechanical properties of VDM®
Powder 718 result from the γ’’-formation during precipitation hardening.
VDM® Powder 718 can be used for many demanding applications. Originally, it was developed and used for static and
rotating components in aircraft turbines such as housings, mounting elements and turbine disks.
The material can also be used for static and rotating components in stationary gas turbines, rocket drives and spacecraft, motor vehicle turbo chargers, high-strength screws, springs and mounting elements, and for heat-resistant tools in
forgeries, extruders and separating shearers.
The variant VDM® Powder 718 CTP, which is designed specifically for the requirements of the oil and gas industry, is
more and more often being used in drilling equipment and pump shafts.
