duplex stainless steelA grain size gradient layer material was produced by means of surface mechanical attrition treatment on a UNS S32304 duplex stainless steel. In this study, the mechanical property was characterized by tensile test, while microstructure was investigated by transmission electron ...
the applied fast cooling rate seems to be a good compromise for mechanical properties and microstructures, nevertheless further tests should be carried out in order to examine different cooling rates.Originality/value: The use of elemental powders added to a stainless steel base showed its potentialiti...

In addition, duplex stainless steel can be more susceptible to cracks in hydrogen sulfide-containing environments. But duplex and super duplex are more resistant against pitting and chloride stress cracking corrosion compared to austenitic stainless steels. In addition, the mechanical properties of duplex...
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...

Duplex stainless steels (DSSs) are promising materials in many fields due to their excellent corrosion resistance and mechanical properties, which are resulted from their microstructure consisted of a roughly equal amount of austenite and ferrite phases. As a revolutionary production technology, additive ...
ASTM A790 S31803 DUPLEX Stainless Steel PIPE ASTM A790 S31803 is a specification for duplex stainless steel pipe. Duplex stainless steel is a type of stainless steel that contains both austenite and ferrite phases in its microstructure, which gives it enhance...
