Introduction

Both of the specifications of UNS.S32205 and UNS.S31803 were initially captured as UNS S31803. However, a number of the leading manufacturers were consistently producing this grade to the upper end of the allowable specification. This reflected their desire to maximize the corrosion performance of the alloy, aided by the development of the AOD steelmaking process that allowed tighter control of composition. 
In addition, it also allowed the level of nitrogen additions to be influenced, rather than just present as a background element. Therefore, the highest-performing duplex grade sought to maximize the levels of chromium (Cr), molybdenum (Mo), and nitrogen (N). The difference between a duplex alloy whose composition meets the bottom of the specification, versus one that hits the top of the specification can be several points based upon the formula PREN = %Cr + 3.3 %Mo + 16 % N.
In order to differentiate the duplex stainless steel produced at the top end of the composition range, a further specification was introduced, namely UNS S32205. Duplex stainless steel made to the S32205 (F60) caption will fully meet the S31803 (F51) caption, whereas the reverse is not true. Therefore S32205 can be dual-certified as S31803.
Duplex S32205 gives better-guaranteed corrosion resistance, but much of the Duplex S31803 currently produced also complies with Duplex S32205. 
2205 is not generally suitable for use at temperatures above 300ºC as it suffers from precipitation of brittle micro constituents, nor below -50ºC because of its ductile-to-brittle-transition.
SAF 2205® is a registered trademark for Sandvik.
