2205 is the most widely used duplex (ferritic/austenitic) stainless steel grade. It finds applications due to both excellent corrosion resistance and high strength. The standard duplex S31803 composition has over the years been refined by many steel suppliers, and the resulting restricted composition range was endorsed as UNS S32205 in 1996.[price]Steel grades, Properties and Global Standards[steel]Steel and steel is introduced, including chemical composition and mechanical performance data, each steel grade property.
