Jinay Metals is a reputable brand in the Middle East for high-quality Duplex Steel Weld Neck Flanges because we place a strong emphasis on customer satisfaction and product innovation.
Duplex steel weld neck flanges are composed of approximately 22–25% chromium, 4–7% nickel, 2–3% molybdenum, and small amounts of nitrogen, manganese, and silicon, with the balance being iron. This dual-phase microstructure of austenite and ferrite provides excellent strength and corrosion resistance. Mechanically, they exhibit high tensile strength (typically 620–880 MPa), yield strength around 450–550 MPa, and good elongation (25–30%). These flanges offer superior resistance to stress corrosion cracking, pitting, and crevice corrosion, making them ideal for demanding chemical, marine, and oilfield applications.
