Specifications

 

In Power Station Equipments,The choice of condenser tubes is vital to the investment and maintenance costs of the whole equipments. LSI 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.

Chemical Composition:

S44660 super ferritic stainless steel tube is their high contents of Chromium and Molybdenum, and it has Titanium and niobium as stabilizing elements. The organization of material makes them with high strength properties, good elongation and low rate of work hardening.
