Customers can select a number of processing options to produce UNS S21900 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 S21900 plates,sheets,coils,strips to a #4 polish, #6 Polish, #7 polish or a #8 mirror finish. Our UNS S21900 plate,sheets,coils,strips can be polished on one side or two sides.

In order to control the quality of UNS S21900 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 S21900 is a high-manganese nitrogen strengthened stainless steel. Nitronic 40 properties include high strength in the annealed condition, excellent resistance to corrosion at high temperatures, readily weldable and it can also be fabricated.

We could produce UNS S21900 plates,sheets,coils,strips as per the standard of ASTM B463
