Customers can select a number of processing options to produce UNS S31803 plate to their exact specifications, reducing materiel costs, production time, scrap and internal handling. All stainless steel grades of plate can be cut

We can polish nearly any UNS S31803 plates,sheets,coils,strips to a #4 polish, #6 Polish, #7 polish or a #8 mirror finish. Our UNS S31803 plate,sheets,coils,strips can be polished on one side or two sides.

In order to control the quality of UNS S31803 plate,sheets,coils,strips,Test pieces are cut from each plate,sheets,coils,strips and sent to our Metallurgical Laboratory, where, aided by a computerized Certificate of Test system, experts determine if the plate,sheets,coils,strips meet all requirements for shipment. Each plate,sheets,coils,strips is analyzed on an optical emission spectrometer to verify chemical content. The microstructure of the plate,sheets,coils,strips is examined for strength, ductility, and corrosion resistance. All additional scrap is separated by grade and returned to a melt shop for recycling

UNS S31803 is a duplex stainless steel designed to combine improved resistance to stress corrosion cracking, pitting, crevice corrosion and high strength when compared with other stainless alloys.


We could produce UNS S31803 plates,sheets,coils,strips as per the standard of ASTM B463
