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

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.
