LDX 2101 PLATE
LDX 2101 (UNS S32101) is a 21.5% chromium, 5% manganese, 1.5% nickel, 0.45% molybdenum lean duplex stainless steel with corrosion resistance superior to 304L and comparable to 316L. LDX 2101 possesses both superior strength and greater chloride stress-corrosion cracking resistance than conventional 300 series stainless steels. The enhanced mechanical strength of LDX 2101 enables it to be used in thinner cross-sections which can provide significant cost savings to the end user. LDX 2101 was designed to be a low nickel general purpose substitute for 304 and 304L.

General Properties
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.
The high chromium and nitrogen content of LDX 2101, combined with an addition of molybdenum, provide very good resistance to localized and uniform corrosion. The duplex microstructure contributes to the alloys high strength and resistance to chloride stress-corrosion cracking. 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.
The enhanced mechanical strength of LDX 2101 is far superior to conventional 300 series stainless steels enabling it to be used in thinner cross-sections which can provide significant cost savings to the end user.
LDX 2101 exhibits good abrasion and erosion resistance and can be fabricated using standard shop practices developed for duplex stainless steels.
