We are Manufacture, Suplier & Export of UNS NO S31803 Socket Weld Forged Fittings that are actually manufactured from High Quality of Standard Raw Materials and are designed as per with national and international standards. When it comes to the fabrication of Duplex Steel S31803 Socket Weld Forged Fittings (also referred as WNR 1.4462 Forged Fittings), we have the experience and knowledge to make sure it is engineered, built and inspected to the highest standards. Duplex Steel UNS S31803 Forged Socket Weld Fittings has good weldability and can be welded by several methods.
Designed to combine improved resistance to stress corrosion cracking, pitting and crevice corrosion, these Duplex Steel UNS S31803 Forged Socket Weld Fittings is roughly double the strength of standard austenitic stainless steel. Our Duplex S31803 Socket Weld Cross Fittings provide meaningful results relating to many practical service applications where resiststance SCC in two sodium chloride-containing environments.
