Duplex steel, or duplex stainless steel, is a type of stainless steel that has a two-phase microstructure consisting of approximately equal amounts (~50%) of austenite and ferrite phases, although in commercial alloys the ratio may be 40/60. This combination of phases gives duplex steel its name "duplex," meaning "two-fold" or "double."

PREN = %Cr + 3.3 %Mo + 16 %N. Depending on the PREN Number values, Duplex Stainless Steel is categorized into four grades. Lean duplex grades (PREN range: 22–27): No deliberate Molybdenum addition. mainly used in the building and construction industry for bridges, pressure vessels, or tie bars.Example: S32001, S32101, S32304, S32202.
