Credibility ,Duplex stainless steel 2205 UNS S32305/S31803 is a 22% chromium, 3% molybdenum, 5-6% nickel, nitrogen alloyed duplex stainless steel with high general, localized, and stress corrosion resistance properties in addition to high strength and excellent impact toughness.
Duplex stainless steel 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.
Duplex stainless steel 2205 has below capability:
l High intensity and good impact toughness
l It can bear stress corrosion well
l Good ability to avoid patch and crack
l Low heat expand modulus and better heat transmit
l High pressure work
l Weldable
