ASTM A268 UNS S44660 Stainless Steel Seamless Tubes And Pipes
ASTM A268 UNS S44660 Stainless Steel Seamless Tubes And Pipes
The ferritic structure of UNS S44660 stainless steel provides a high strength/low work hardening material
with good ductility. These properties allow high design stress limits with good fabrication characteristics.
Because of the nickel addition, stainless S44660 ( 26-3-3 ) has a lower ductile-to-brittle transition temperature than
similar ferritic steels without nickel additions.
S44660 stainless is specially engineered to reduce life-cycle cost by preventing tube leaks, ensuring tube cleanliness,
eliminating chemical treatment and reducing CO2 costs.

Characteristics
- Significantly higher modulus that allows the use of a lighter wall with less problem of vibration
- Higher steam and water droplet erosion resistance allowing a greater cushion in cases where upset conditions may occur
- Weldability to other stainless steels
- Higher strength and modulus which allows more tolerance for those tough designs and installations
- Superior Corrosion Resistance
Typical applications
used in power plant condensers, heat exchangers and desalination plants due to its excellent corrosion resistance,
good thermal conductivity, and superior mechanical and physical properties.
