Metrode 2205XKS description: Duplex stainless steel pipe, plate, fittings and forgings have an approximate 50:50 microstructure of austenite with a ferrite matrix. This, coupled with general alloying level, confers:
- high strength compared with standard austenitic steels, eg type 316L.
- good general corrosion resistance in a range of environments.
- high resistance to chloride induced stress corrosion cracking (CSCC).
- high resistance to pitting attack in chloride environments, eg seawater.
These alloys are finding widening application in the offshore oil/gas, chemical and petrochemical process industries, eg pipework systems, flowlines, risers, manifolds etc.
