Company Profile
 |
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.
Duplex stainless steel S31803 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
