Duplex Stainless Steel 2205 S32205 S31803 By yaang.com

Duplex Stainless Steel 2205 S32205 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 S32205 S31803 provides pitting and crevice corrosion resistance superior to 316L or 317L austenitic stainless steel 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.The advantage of a duplex structure is that it combines the favorable qualities of aferritic alloy stress corrosion cracking resistance and high strength with austenitic alloy ease of fabrication and corrosion resistance.

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 is a mixed microstructure of austenite and ferrite (50/50) which has improved strength over ferritic and austenitic stainless steel grades with similar corrosion resistance qualities. 

One of the main attractions of duplex stainless steel is cost – due to the materials increased yield strength it is often possible to reduce the thickness of material making it much cheaper than a comparative austenitic stainless steel grade.
