Alloy LDX 2101 Super Duplex Stainless Steel
Alloy LDX 2101 is a low-nickel, nitrogen enhanced lean duplex stainless steel developed for general-purpose use. The austenitic-ferritic (duplex) structure of the alloy is balanced to approximately equal amounts of ferrite and austenite in the solution-annealed condition.
Alloy LDX 2101 possesses both superior strength and greater chloride stress-corrosion cracking resistance than conventional 300 series stainless steels.
The corrosion resistance of LDX 2101 is generally good making it suitable for use in a wide variety of applications. In most environments, it is superior to 304L stainless steel and comparable to the molybdenum containing 316L stainless steel.

Corrosion Resistance

The 300 series stainless steels are used extensively in numerous process industries due to their overall general corrosion resistance. The corrosion resistance of LDX 2101 is generally better than 304L and comparable to 316L making it suitable for use in a wide variety of industries and applications.
