This is made possible due to duplex stainless steel having an approximate 50% ferrite and 50% austenite microstructure. This allows them to combine the many benefits that are tied to both ferritic and austenitic stainless steels.<\/p><p style=\"text-align: justify\">With almost double the mechanical strength of the common grades stainless steel (304 &amp; 316), duplex has been picking up speed in terms of global usage due to the cost savings one might get due to the reduction of thickness requirements and as well as overall life cycle replacement cost savings due to its superior corrosion resistance.
