Powder 718 CTP
Due to its excellent corrosion resistance and its good work-ability, Powder 718 CTP is versatile in use in the oil and
gas industry, in the offshore industry and in marine engineering. The conventionally manufactured 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.
Powder 718 CTP is the powder variant of an age-hardenable nickel-chromium-iron-molybdenum alloy for use in
additive manufacturing. Harden-ability is achieved by means of admixtures of niobium, titanium and aluminium.
Powder 718 CTP is characterized by:
- Spherical particles.
- High purity.
- Low oxygen content.
- Excellent resistance to stress corrosion cracking and pitting in chloride-containing media.
- Excellent resistance to stress corrosion cracking and sulphide stress cracking in sour (H2S-containing) oilfield environments.
