ASTM A268 UNS S44660 Cold Rolled Drawn Stainless Seamless Steel Tube
Super ferritic stainless steels tubing (UNS S44660) is specifically designed for applications where
chloride induced pitting, crevice and stress corrosion cracking may be encountered.
Super ferritic stainless steel is used in Electric Power Plant Condensers and Feedwater Heaters,
BOP Exchangers, Various Chemical, Petrochemical and Refining Applications, and Desalination Heat Exchangers.
UNS S44660 stainless steel has a number of attractive physical properties, including low thermal expansion, good thermal conductivity, and a high elastic modulus which provides high stiffness.
High stiffness allows less vibration than with other engineering materials.
The thermal expansion coefficients are similar to those of carbon steel and lower than those of the austenitic stainless steel or copper alloys.
The thermal conductivity is similar to titanium and higher than the austenitic stainless steels of
high nickel alloys. The passive corrosion resistant film is extremely thin, which allows good heat transfer performance.
