Duplex S32205 Fasteners are nitrogen improved duplex stainless steel that was created to combat normal corrosion issues experienced with the 300 series stainless steel. "Duplex" defines a family of stainless steels that are neither completely austenitic, like 304 stainless, nor absolutely Ferritic, like 430 stainless. The structure of S31803 duplex stainless steel comprises of austenite pools encompassed by a persistent ferrite phase.

In the annealed condition, S31803 Fasteners consist of around 40-50 percent ferrite. Frequently referred to as the workhorse grade, Duplex S32205 Fasteners are the most generally utilized grades in the duplex family of stainless steels. One of the benefits of a duplex architecture is that it consolidates the great characteristics of a Ferritic alloy (stress corrosion cracking resistance and high strength) with those of an austenitic alloy (ease of fabrication and corrosion resistance). Use of 2205 Duplex stainless steel should be restricted to temperatures below 600 degrees F. Extended high-temperature exposure can embrittle Duplex Stainless Steel S31803 Fasteners.
