About S32550 duplex stainless steel
S32550 stainless steel is a duplex stainless steel formulated for primary forming into wrought products. Cited properties are appropriate for the annealed condition. S32550 is the UNS number for this material. Alloy 255 is the common industry name.
It has a moderately high thermal conductivity among wrought duplex stainless steels. In addition, it has a moderately high tensile strength and a moderately low ductility.
The characteristic features of high strength and corrosion resistance exhibited by the dual microstructure (austenite, ferrite) associated with duplex stainless steels are found in UNS S32550. It is similar in composition to the more widely used super duplex grade UNS S32760. UNS S32550 has a slightly higher copper level, lower nickel and no deliberate tungsten additions, and is normally supplied to achieve the UNS S32760 PREN requirement of 40.
