Duplex Grades Duplex GradesDuplex stainless steels are extremely corrosion resistant, work hardenable alloys. Duplex stainless steel plate contains relatively high levels of chromium (between 18% and 28%) and low to moderate amounts of nickel (between 1.5% and 8%). The high corrosion resistance ...
Some 25% Cr grades, by this definition, are not “super duplex”. The properties of duplex stainless steels are maintained by careful attention to the microstructural phase balance. Steel makers will aim, by the combined control of alloying elements and heat treatment, to achieve a phase ...
The present paper gives a brief review of the history and some recent developments of duplex stainless steel grades and the improvements made on the standard S32205 DSS lowering the Ni and Mo contents to produce an economical alternative of the well-known grade or in the case of the super...

Its high mechanical strength is similar tothat of other duplex grades and its good corrosionresistance is on par with that of most standard stainlesssteel grades. Combined, these properties can be utilisedto arrive at a design optimised with respect to strength,maintenance, durability and long-term...
Stainless Steel Grades Explained This combination of properties can mean some compromise when compared with pure austenitic and pure ferritic grades. Duplex stainless steel are in most cases, tougher than ferritic stainless steel. Strengths of duplex stainless steels can in some cases be double that ...

The initiation and propagation of crevice corrosion in natural seawater were evaluated for five different duplex stainless steel grades together with some austenitic grades. A CREVCORR-type assembly was used to simulate crevice configurations involving the use of plastic crevice formers. The standard ...
