VDM® Alloy 718 CTP (2.4668/N07718)

VDM® Alloy 718 CTP is an age-hardenable nickel-chromium-iron-molybdenum alloy. The age hardening is achieved by specific additions of niobium, titanium and aluminum. It can be delivered in the solution-annealed or different age-hardened conditions.

Characteristics of VDM® 718 CTP

The acronym CTP stands for Corrosion - Temperature - Pressure and identifies material variants that are specially tailored to the requirements of the oil and gas industry.

The alloy has a minimum yield strength of 120 ksi and can be ordered with the material designation 120K. Further variants are available with minimum yield strengths of up to 150 ksi.

VDM® Alloy 718 CTP (2.4668/N07718) is characterized by:

Good processing properties in the solution-annealed condition
Good mechanical short and long-term properties, and excellent fatigue strength in the age-hardened condition
Excellent mechanical properties in low temperatures

Applications of VDM® Alloy 718 CTP

Due to its excellent corrosion resistance and its good workability, VDM® Alloy 718 CTP is versatile in use in the oil and gas industry, in the offshore industry and in marine engineering. The alloy 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.
