Duplex Steel is featured with structure of two phases (α and γ) and
has characteristics of both ferritic and austenitic stainless
steel. It has good corrosion resistance and high strength. It is
alloyed with 18%-28% Cr and 3%-10% Ni in the condition of low C.
Some steels also contain the alloy elements such as Mo, Cu, Nb, Ti
and N, etc. Comparing with ferritic stainless, duplex stainless
steel has higher plasticity, ductility and better intergranular
corrosion resistance and weldability. It keeps same 475°C
brittleness with ferritic stainless and high thermal conductivity.
Duplex has improved yield strength, resistance to intergranular
corrosion, stress corrosion, corrosion fatigue and abrasion &
corrosion compared with austenitic stainless steel.
Alloy 2205 UNS S32305/S31803 is a 22% chromium, 3% molybdenum, 5-6%
nickel, nitrogen alloyed Duplex Stainless Steel Pipe with high
general, localized, and stress corrosion resistance properties in
addition to high strength and excellent impact toughness.
Alloy 2205 provides pitting and crevice corrosion resistance superior to 316L or 317L austenitic stainless steel tube in almost all corrosive media. It also has high corrosion and erosion fatigue properties as well as lower thermal expansion and higher thermal conductivity than austenitic.
2101 is a low nickel, lean duplex stainless steel possessing both superior strength and chloride stress-corrosion cracking resistance when compared to 300 series stainless steel.
2304 A lean austenitic-ferritic duplex stainless steel with general corrosion resistance similar to 316, but with yield strength nearly double that of austenitic stainless steel.
S31803 and S32205 are standard duplex stainless steel. A nitrogen, molybdenum enhanced austenitic-ferritic duplex stainless steel with general corrosion resistance similar to 904L, but with a yield strength nearly double that of austenitic stainless steel.
2507 (PREN 40-45), with 25-26 Cr and increased Mo and N compared with the 25Cr grades. A super austenitic-ferritic duplex stainless steel with exceptional strength and corrosion resistance ideal for chemical process, petrochemical, and seawater applications.
