S32205 S31803 1.4462 General Properties

Alloy 2205 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 pipe 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 yield strength is about twice that of austenitic stainless steel tube. This allows a designer to save weight and makes the alloy more cost competitive when compared to 316L or 317L.

Alloy 2205 is particularly suitable for applications covering the -50°F/+600°F temperature range. Temperatures outside this range may be considered but need some restrictions, particularly for welded structures.
