Salem Stainless Steel may be a known trader of Duplex Steel 2205 Plates, which has Good to excellent resistance to pitting and crevice corrosion. Duplex 2205 Plates Duplex 2205 Stainless steel Plates (both ferritic and austenitic) is employed extensively in applications that need good corrosion resistance and strength. Combining many of the beneficial properties of both ferritic and austenitic steels, 2205 Duplex Stainless steel is that the most generally used duplex Stainless steel grade. Duplex Stainless steel UNS S32205 Plates is nitrogen-enhanced duplex Stainless steel that was developed to combat common corrosion problems encountered with the 300 series stainless steels. it’s high mechanical strength and high resistance to worry corrosion cracking and corrosion fatigue.
