Super Ferritic Stainless Steel Tubing UNS#S44660/UNS#S44735

Thanks to its outstanding resistance to general and localized corrosion attack properties, Titanium has been successfully established as the commonly used material for seawater cooled heat exchanger tubing,be it for power plants' surface condensers, thermal desalination plants'heat exchangers or heat exchangers used in the chemical and petrochemical processing industry. In the current material market context in which Titanium price has increased significantly, engineering companies and end-users have shown an increasing interest for more cost-effective alternative solutions using what are called super alloys which are highly alloyed stainless steels showing a far better corrosion resistance than conventional stainless steels.That is the background for the inventation of UNS S44400 and UNS S44660 super-ferritic stainless steel tube. Nowadays, with the development of VOD technology and advanced tube processing technology, people get great profit from such kind of new material. LSI devote all his energy in such material and got great achievement in such kind of material. We and our people are most professional in such material, when you order it or has any queries, please contact us.
