Duplex Steel Pipe Fittings, which have their austenite and ferrite microstructure, generally still consist of 22-25% chromium, 4-7% nickel, and 2-4% molybdenum with nitrogen for strength and corrosion resistance. The mechanical properties of duplex steel pipe fittings take on excellent values ranging from 620 to 850 MPA for tensile strength, 450 to 600 MPA for yield strength, and about 25% elongation. They demonstrate excellent resistance to pitting corrosion, crevice corrosion, and stress corrosion cracking making them a very durable material for fabriication in realistic contexts and climes. Additionally, their weldability and toughness are other reasons for their increased use by industrial and marine application engineers today.
