UNS S31803/2205 is a duplex grade with a ferritic-austenitic microstructure. The alloy consists of around 40-50% ferrite in the annealed condition. The duplex microstructure has the high strength of the ferritic grades whilst retaining the corrosion resistance of the austenitic grades. It is not uncommon to see the metal used as a practical solution to chloride-induced stress cracking, which is the achilles’ heel of stainless steel. Duplex Stainless Steel S31803 is the most common duplex grade in the market with high mechanical strength. It is widely used in Oil & Gas Industry, hydro power, pressure vessels, pulp & Equipment for the Paper Industry, Paper Industry, structural components and chemical tankers. The alloy is not intended to be used at temperatures above 300°C due to embrittlement.
