Duplex s32205, s31803 is a nitrogen enhanced duplex stainless steel that was developed to combat common corrosion problems encountered with the 300 serious stainless steel. "duplex" describes a family of stainless steel that are neither fully austenitic, like 304 stainless, nor purely ferritic phase. In the annealing condition, 2205 contains approximately 40-50% ferrite. Often referred to as the work horse grade, 2205 is the most widely used grade in the duplex stainless tube.

As welded tubing
As welded tubing is our least expensive product line, and is manufactured by running coils of annealed strip through a cold roll forming process. It is continuously welded using appropriate shielding gases for each alloy to prevent oxidation of the seam. With as welded tubing, the seam is clearly visible on both the exterior and interior of the tube, but the size of the weld bead is held within strict tolerances.
Typical applications for as welded tubing include tubular heating elements for both industrial and consumer targeted end products, beverage or fluid transportation systems, mechanical devices, automotive applications, and heat exchange devices.
Bead rolled tubing
Bead hammered tubing is initially formed with a process identical to that of as welded tubing, except that an additional, special cold roll forming process with an interior mandrel support is added to smooth both the interior and exterior weld seam. As a result, the seam is nearly invisible on both the exterior and the interior, creating a tube that is an excellent, lower cost substitute for seamless tubing.
Applications for bead hammered tubing include anything where interior and exterior smoothness are important, such as certain liquid and gas handling applications, and fabricated applications where exterior fittings require a smooth surface.
