Super Ferritic Stainless Steel Tube For Industry Solution - China

Product Description

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.

• Business Description: Since LSI s first successful supplying of such great material for China Steel Corporation, LSI has completed more than 500 Kilometers S30815 (Alloy 253MA, EN1.4825) tubes and pipes for domestic and overseas customers and got 100% satisfaction with 0 complaints from customers and end users till today.
  
  UNS S30815, equal to Alloy 253MA and EN 1.4835 , include rare earth metals (REM) and suitable for very high temperature applications (700 1100℃), particularly for conditions involving erosion corrosion in oxidizing and neutral environments, as well as sulfur attack.
  
  The excellent mechanical strength at high temperatures allows higher loads or thinner wall thickness than common high temperature steels e.g. 309S (EN 1.4833) and 310S (EN 1.4845).
