| Application areas | Due to its excellent corrosion resistance and its good workability, VDM® Powder 718 CTP is versatile in use in the oil and gas industry, in the offshore industry and in marine engineering. The conventionally manufactured VDM® Alloy 718 CTP has proven itself well, especially for oilfield completion equipment in very demanding environments containing H₂S, CO₂, and high chlorides. The alloy has also proven itself for highly stressed oilfield components. | |
| Corrosion properties | As a result of the high chromium and molybdenum concentrations, conventionally manufactured VDM® Alloy 718 CTP has very good general corrosion resistance and pitting corrosion resistance in many environments. By virtue of its high nickel content, it also has good resistance against stress corrosion. | |
| Other | VDM® Powder 718 CTP has an austenitic microstructure with multiple phases. By means of different heat treatments, graduated mechanical properties of the material can be achieved. The excellent mechanical properties of VDM® Powder 718 CTP result from the γ‘‘-formation during the precipitation hardening. | |
