The 2205 is the most widely used of the duplex stainless steels occupying more than 80% of the duplex stainless steel market. The 2205 alloy provides better corrosion resistance in various environments where 316L is generally used with an added advantage of its higher yield strength. All 2205 alloys are metallographically examined to ensure that the shipped product is free from presence of detrimental phases such as sigma. It is often used in form of welded pipe or tubular components. The alloy has also been applied as a formed and welded sheet product in environments where resistance to general corrosion and chloride stress corrosion cracking is important
