Home > Duplex Steel Flanges
A well-known producer and supplier with headquarters in Dubai, United Arab Emirates, Jinay Metals specializes in premium duplex steel flanges. We serve a variety of industrial sectors, such as construction, petrochemical, and oil and gas, and are renowned for our precision engineering and longevity. Because our flanges are made from premium-grade duplex stainless steel, they will last a long time even in the most demanding conditions and exhibit remarkable strength and resistance to corrosion. Jinay Metals has established a solid reputation among customers both domestically and abroad thanks to its dedication to quality, prompt delivery, and affordable prices. We provide dependable, personalized flange solutions for each project by combining cutting-edge manufacturing processes with strict quality control.
Duplex Steel Flanges are engineered with a balanced microstructure of austenite and ferrite, typically containing 18–25% chromium, 3–7% nickel, 2–4% molybdenum, and small amounts of nitrogen for enhanced strength and corrosion resistance. This composition provides superior resistance to pitting, stress corrosion cracking, and general corrosion in harsh environments. Mechanically, duplex steel offers high tensile strength (approximately 620–850 MPa), excellent yield strength (around 450–620 MPa), and good elongation (25–35%), making it ideal for demanding applications in oil, gas, chemical, and marine industries where both durability and reliability are critical.
