LDX 2101®
LDX 2101® is a lean duplex stainless steel designed for general purpose use. Like other duplex stainless steels, LDX 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, LDX 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 LDX 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.
