The outer diameter of UNS S31703 pipes that we could do is from 0.4MM to 850MM,The thickness of UNS S31703 that we could do is from 0.12MM to 100MM

We could meet size tolerance for UNS S31703 Pipes is as follows:OD : + ± 0.5% of specified diameter based on circumferential measurement. Thick : Minimum thickness at any point not more than 0.3 mm under nominal thi,Out of Roundness : difference between maximum and minimum OD 1% ,Straightness : 3 mm in 3 mtrs

Length : As per customer specification

As per surface finish of S31703 pipes, we could do pickled and polish into bright surface as per the requirement of the clients, also for bright surface of UNS S31703 pipes, we could meet 2D finish.No. 4 Finish,No. 6 Finish,No. 7 Finish as per the requirement of the clients

UNS S31703 has the same high strength and corrosion resistance as 317 steel but can produce stronger welds due to the low carbon content.
