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.

 

Features

  • The ferritic structure 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, Super Ferritic Stainless Steel has a lower ductile-to-brittle transition temperature than similar ferritic steels without nickel additions.
  • 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
