Product Description

UNS31803 Duplex Steel Weld Neck Flange Class 300

This long weld neck flange is made from UNS31803 duplex steel for chemical and metallurgical service. It is forged and CNC machined to ANSI, DIN, JIS and ASME standards, including ANSI B16.5 and ASME B16.47, with a pressure rating of 0.6~32 MPa. Duplex steel combines high strength with excellent resistance to chloride stress corrosion cracking, so the flange performs reliably in aggressive process media.
