Our austenitic-ferritic (duplex) steels supplied as rolled round bars offer very good mechanical properties combined with good corrosion resistance in acidic and chloride-based environments as well as good stress corrosion resistance. There is considerable demand for these steels in the chemical and petrochemical sector, seawater desalination facilities, and the oil and gas industry.
