ASTM A790 UNS S32760 SDSS seamless and welded pipes

The ASTM A790 UNS S32760 Welded Pipe is stronger than the cold drawn seamless pipes in general. They are easy to weld upon as well. The SA 790 UNS S32760 Tube produced less carbide precipitation which in turn avoids intergranular corrosion. So the Duplex S32760 UNS Seamless Pipe is also resistant to localized corrosion after welding.
