Kiah Metallurgical Indian Exporters is a renowned manufacturer, supplier and exporter of Duplex Steel S31803 Forged Fittings, which is the most widely used duplex (Ferritic / Austenitic) stainless steel grade. We acknowledge the significance of the ability to provide and supply raw and pre-machined Duplex UNS S31803 Forged Fittings that can be relied upon in terms of quality, traceability to mill source, supply accuracy, and rapid delivery. Duplex UNS S31803 Forged Elbow is extremely corrosion resistant and works hardenable alloys. Duplex UNS S31803 Forged Tee has high general corrosion resistance. Duplex UNS S31803 Threaded Cross has good weldability in thick plates. Duplex UNS S31803 Reducing Tee Fittings is duplex stainless steel with a 50 / 50 austenite, ferrite microstructure. Duplex UNS S31803 Forged Equal Tee is a two-phase, ferritic, austenitic 22 % chromium, 5 to 6 % nickel alloyed stainless steel, and 3 % molybdenum. Duplex UNS S31803 Forged Threaded Fittings are formed based on the crystalline structure of stainless steel.
Duplex Steel UNS S31803 Forged Pipe Fittings
Duplex UNS S31803 Forged Socket Weld Fittings is nitrogen-enhanced duplex stainless steel that was developed to combat common corrosion problems encountered with the 300 series stainless steels. Duplex UNS S31803 Forged Coupling combines improved resistance to stress corrosion cracking, pitting, crevice corrosion and high strength in comparison with other stainless steel grades. Duplex UNS S31803 Forged Socket Weld Elbow Fittings in addition to having high mechanical strength, also exhibit very high resistance to corrosion and stress corrosion cracking.
