The process industries have used 300 series stainless steels for many years where the corrosion resistance of carbon steel is inadequate. Where stainless steels have proved inadequate there has been a tendency to utilize high nickel alloys, with a greatly increased cost. The present paper reviews the different grades of duplex stainless steel and shows how their superior corrosion and stress corrosion cracking resistance, plus their high strength, can be utilized to provide cost effective alternatives to the high nickel alloys. The use of alternative design codes to take advantages of the properties of duplex alloys is discussed. Data is presented to show the resistance of duplex stainless steels to a variety of chemical environments. The use of duplex stainless steels and the reason for their selection in a number of applications is reviewed.
