ASTM A790 UNS S32750 is a variation of super duplex steel. The
duplex steel material is made up of chromium and molybdenum alloy.The duplex has the ferritic and austenitic steel properties in its
metallurgic microstructure. This gives the name duplex to the material. The SA 790 UNS S32750
belongs to the super duplex category. There are three groups of
duplex, namely the duplex, super duplex and lean duplex. Each of
them has their own composition and specific mechanical properties
as a result. As the Super Duplex UNS S32750 Pipe belongs to the
super duplex category, it is used for high strength and high
corrosive applications. The alloy has 25% chromium in its
composition along with 4% molybdenum and 7% nickel. This material
composition makes it stronger and much corrosion resistant than the
ordinary duplex material.
