Lean Duplex 2101 is a lean duplex stainless steel designed for general purpose use. Like other duplex stainless steels, Lean Duplex 2101 provides both superior strength and chloride stress corrosion cracking resistance compared to 300 series stainless steels. The use of manganese ensures proper ferrite-austenite phase balance, while allowing a reduction in nickel content. As a result, Lean Duplex 2101 is priced competitively with 304/304L and 316/316L stainless steels. The combination of a duplex structure and high nitrogen content provide significantly higher strength levels than 316/316L stainless steel. Often a lighter gauge of Lean Duplex 2101® can be utilized, while maintaining the same strength as a 300 series fabrication. The resultant weight savings can dramatically reduce the material and fabrication costs of a component. Lean Duplex 2101 is magnetic, similar to all duplex stainless steels, as it contains an even balance of ferrite and austenite. 316L stainless is a fully austenitic stainless steel and is therefore non-magnetic.
