Duplex Stainless Steel Pipe  is the most common duplex product we supply, we can also deliver Duplex 2304 and Duplex 2507 with reduced lead times as these alloys are stocked. 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 Stainless Steel or 317L 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.

Standard: ASTM/ASME A789/SA789, A790/SA790

Steel Grade: UNS S32750, S31803, S32760 etc.
