UNS S44660 Seamless Tube, Condenser Solution

UNS S44660 Seamless Tube, Condenser Solution

• General introduction of UNS S44660:
  • 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, S44660 has a lower ductile to brittle transition temperature than similar ferritic steels without nickel additions
  • In power station equipment, the choice of condenser tubes is vital to the investment and maintenance costs of the whole equipment
  • We are going to forecast the direction of the market of application of super ferritic stainless steel tubes in condensers and analysis the advantages of super ferritic stainless steel tubes compared with normal austenitic stainless steel tubes and titanium tubes from the aspects of chemical compositions, anti-corrosion capabilities, physical properties and mechanical properties of super ferritic stainless steel tubes

• Characteristics of UNS S44660:
  • 1.Super ferritic stainless steel is a kind of alloy be used for anti-pitting corrosion, crevise corrosion and stress corrosion under the environment of chloride
  • 2.It has good heat conductivities, high anti-chloridion corrosion and marine life corrosion, extremely high modulus o felasticity, high fatigue strength and hardness impact attack resistance, coefficient of linear expansion will be the same as carbon steel and unit price will be equal or economic than titanium tubes
  • 3.Weldability to other stainless steels
  • 4.Compared with titanium, not easier to have hydrogen brittleness phenomenon

• Dimensions of UNS S44660 tube we provide:
  • OD: 12.7-38.1mm
  • Wall thickness: 0.4-2.5mm
  • Max. length: 20 meters

We supply UNS S44660 seamless tube as well as welded tube
