ASTM A790 UNS S32750 / S32760 Super Duplex 2507 Seamless Pipe

S32750 Stainless Steel Tubes, largest independent Manufacturer of Duplex 2507 Pipe in India

Duplex stainless steel is a family of steel alloys that comprise chromium, nickel and molybdenum in their composition and they have a dual nature of steels. The austenitic and ferritic steel phases are present in the metallurgic microstructure of this family and as a Super Duplex Stainless Steel Pipe Manufacturer we produce all kinds of pipes in the super duplex range.

Duplex has three major categories; the standard duplex, the super duplex and the lean duplex. The super duplex has very high corrosion resistance properties due to the high chromium addition. The UNS S32750 Stainless Steel Tubes are very much corrosion resistance especially to chloride ion rich environments. This special feature enables them to be used in the marine and sea water industries primarily.


What is Super Duplex Pipe?

The Super Duplex 2507 Pipes can also withstand a high temperature and pressure condition. There are different makes of the ASTM A790 Super Duplex Seamless Pipes which could be drawn and are smooth. The welded pipes are less smooth but are much stronger. The Super Duplex S32760 Tube could be heat treated and hardened. We also produce the special Werkstoff No 1.4410 Super Duplex EFW Pipe for strength demanding applications. Our Super Duplex Welded Pipe is much harder and is easy to weld with. Great Steel & Metals also produces S32750 Super Duplex Erw Pipes in all available standards and schedules. The pressure ratings differ per schedule of the pipes. We can provide our customers with a full range of products and a full list is available upon contact.
