Duplex Steel forged Fittings are tow structures viz. Austenitic and Ferritic. Mechanical properties of DS Forged Fittings is good. These Steel fittings also, have excellent resistance to corrosion. Duplex Steel forged Fittings are two times stronger in comparison to that of austenitic and ferritic steel grades. The Ductility and toughness of DS is also better in comparison to other steels. Stress-corrosion cracking is well resisted by Duplex Steel forged fittings. Two varieties of Duplex Steel Forged Fittings include the Socket-weld and Threaded Fittings. The types in these are Bushings, half & full couplings, reducing couplings, Elbows, Unions and Stub-Ends. Standards to govern these DS Forged Fittings are ASME B16.11 and ASME B1.20.1. These standards maintain production quality of Socket-Weld and Threaded separately. Apart from this the forged fittings also undergo various mechanical tests that maintain the production quality. The alloying elements in DS is lower than other steels, making it highly cost effective. Piping systems make use of forged fittings to create branch piping systems, and to change diameter and direction without alterations.
