Product Description
UNS S31803 Duplex Steel 2205 Plate & Coils
Duplex 2205 stainless steel combines ferritic and austenitic properties, offering exceptional corrosion resistance and high strength. The S31803 grade has been refined into UNS S32205, providing superior corrosion resistance. This material is not recommended for use above 300°C or below -50°C due to micro-constituent transformations.
