Duplex Steel 31803/2205 is a commercially duplex stainless steel renowned for its exceptional performance in harsh environments. It offers remarkable resistance to stress corrosion cracking, corrosion under thermal seawater conditions, and excellent pitting resistance, making it suitable for a wide range of applications.
This duplex grade features a ferritic-austenitic microstructure, typically containing around 40-50% ferrite in the annealed condition. The duplex microstructure combines the high strength of ferritic grades with the corrosion resistance of austenitic grades, making it an ideal solution for chloride-induced stress cracking, a common vulnerability of stainless steel.
