UNS S32750 tube
What is UNS S32750 tube?
The UNS S32750 is a variation of super duplex steel, which has chromium and molybdenum in its alloy. The material has both ferritic and austenitic properties in its metallurgical microstructure. The UNS S32750 Tubes are known for their high strength and superior corrosion resisting properties. The tubes are available in both seamless and welded variants, and they are chosen according to the application needs.
The ASTM A790 UNS S32750 Seamless Tube are available in both hot rolled and cold drawn variants. The cold drawn seamless tubes come with a more precise dimension, but there is a restriction in its length. The Super Duplex S32750 Welded Tube is available in bigger lengths. They have less precision but are more cost-effective than the seamless tubes.
