Duplex Steel Pipes
Duplex Steel pipes have two structural phases viz. Austenitic and Ferritic. Mechanical properties of Duplex Steels are outstanding. Also, the corrosion resistance properties in these pipes is excellent.
When compared to regular austenitic and ferritic steel grades, Duplex Steels are stronger. In comparison to only ferritic steels the ductility and toughness of Duplex steel pipes is much better. Chloride pitting and crevice corrosion is not a problem for these pipes as the nitrogen, chromium and molybdenum content make it highly resistant to it. These duplex steel pipes are immune to stress-
