Citizen Metals is a distinguished manufacturer of a wide range of Duplex UNS S31803 Flanges, which is the most widely used duplex (ferritic / austenitic) stainless steel. Duplex Steel UNS S31803 Slip On Flanges are extremely corrosion resistant and work hardenable alloys. ASTM A182 Duplex S31803 Blind Flanges contains larger amounts of chromium in comparison with other steels and thus has good corrosion resistance. Duplex Steel Spectacle Blind Flanges has high resistance to various types of corrosion. Duplex Steel UNS S31803 Socket Weld Flanges has high general corrosion resistance. ASME SA 182 Duplex S31803 Weld Neck Flanges combines good mechanical strength and ductility with moderate to good corrosion resistance in a variety of environments.
Duplex Alloy Threaded Flanges combines improved resistance to stress corrosion cracking, pitting, and crevice corrosion. Duplex Steel UNS S31803 Lap Joint Flanges is applied in the industrial fields like chemical plant, seawater pump, seawater desalination plant, and so on. ASTM A182 Duplex S31803 Ring Type Joint Flanges is not intended to be used at temperatures above 300 Degree C due to embrittlement. Duplex Steel Orifice Flanges is often used for oil and gas exploration and processing equipment – piping, tubing, and heat exchangers. Duplex Steel UNS S31803 Reducing Flanges also has yield strength, double that of conventional austenitic stainless steels. ASME SA 182 Duplex S31803 Tongue & Groove Flanges has good weldability in thick plates.
