LDX2101 Overview
LDX 2101 is a low-alloyed, general purpose lean duplex stainless steel. It possesses properties such as high mechanical strength, similar to that of other duplex steels, and good corrosion resistance. Compared to 300 series stainless steels, 2101 duplex stainless provides superior strength and greater chloride stress corrosion cracking resistance.
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 304L and 316L stainless steels. Due to its relatively low alloying content, it is less prone to precipitation of intermetallic phases than other duplex steels.
Corrosion Resistance
The corrosion resistance of LDX2101 is generally good, and therefore is suitable for use in a wide range of general-purpose applications and environments. Attributable to its duplex structure, LDX 2101 offers an excellent resistance to stress corrosion cracking. It also offers corrosion resistance comparable to 304L and 316L stainless steel, making it an excellent candidate to replace 300 series stainless in a wide variety of applications.
