Duplex Steel Pipe Fittings

Duplex steel Pipe Fittings contain austenitic and ferritic steel structure. These pipe fittings are known for their outstanding mechanical properties. Duplex Steel Pipe Fittings have excellent resistance to corrosion.

The strength in Duplex Steel Pipe fittings is superior when compared to only austenitic or ferritic steels. The toughness and ductility of Duplex steel is also better in comparison to that of ferritic steels. DS Pipe Fittings are immune towards Chloride pitting and crevice corrosion, owing to the nitrogen, molybdenum and chromium present in them. Nickel and Molybdenum is added in less quantity, when compared to other austenitic grades. Cost is also reduced when the alloyants are added in lesser amounts. Pipe fittings made in DS are available in type like Elbows, Tees, Reducers, Pipe Bend, Cross, Pipe Cap and Stub End. DS also has a higher tensile strength, in comparison to normal austenitic steels. Applications like hot water tanks, brewing tanks, and processing plants use Pipe Fittings made from duplex steels. DS Pipe Fittings are also heavily used for their stress corrosion cracking resistance.
