Features of Nickel Alloy Coiled Tubing

High creep fracture strength

Resistant to oxidation at 1800°F

Good fatigue resistance

Excellent weldability

Excellent resistance to chloride pitting and crevice corrosion

Resistant to chloride ion stress corrosion cracking

Resistant to seawater under flowing and stagnant conditions as well as under contaminated conditions


Applications: Chemical process industry and sea water application. Alloy 625 is used in short term applications at temperatures up to 816℃. For long term service, it is best restricted to a maximum of 593℃, because long term exposure above 593℃ will result in significant embrittlement.
