LDX 2101 alloy is a low nickel, lean duplex stainless steel that is designed with both superior strength and chloride stress-corrosion cracking resistance, which are much better than 300 series stainless steels.
LDX 2101 was developed for general-purpose use. High chromium and nitrogen content of this alloy along with molybdenum content provide excellent resistance to localized and uniform corrosion.
LDX 2101 acts as a low nickel general purpose substitute for stainless steel grades 304 and 304L. This alloy possesses good fatigue strength, chloride pitting resistance, and good machinability and weldability.
