Product Description
Duplex Stainless Steel Pipe |Austenitic-Ferritic Stainless Steel Tubes
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 2101 is a low nickel, lean duplex stainless steel possess 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 steels.
2205/S31803 nitrogen, molybdenum enhanced austenitic-ferritic duplex stainless steel with general corrosion resistance similar to 904L, but with yield strength nearly doubles that of austenitic stainless steels.
2507 A super austenitic-ferritic duplex stainless steel with exceptional strength and corrosion resistance ideal for chemical process, petrochemical, and seawater applications.
Duplex stainless steel 2205 has below capability:
High intensity and good impact toughness
It can bear stress corrosion well
Good ability to avoid patch and crack
Low heat expand modulus and better heat transmit
High pressure work
Weldable
