LDX 2101 UNS S32101 Duplex Stainless Steel Pipe By yaang.com

LDX 2101 UNS S32101 is a lean duplex stainless steel designed for general purpose use. 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 stainless steel and comparable to 316L stainless steel.

LDX 2101 UNS S32101 Duplex Stainless Steel is a low-alloyed, general purpose lean duplex stainless steel. It possesses properties such as high mechanical strength, similar to that of other duplex stainless steel, and good corrosion resistance. Compared to 300 series stainless steels, 2101 duplex stainless steel 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 UNS S32101 Duplex Stainless Steel is priced competitively with 304L stainless steel and 316L stainless steel.  Due to its relatively low alloying content, it is less prone to precipitation of intermetallic phases than other duplex stainless steel.

Corrosion Resistance

The corrosion resistance of LDX 2101 uns s32101 duplex stainless steel 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 uns s32101 duplex stainless steel 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.
