Duplex steel flanges are a balanced mixture of austenite and ferrite phases typically containing 21-23% chromium, 4.5-6.5% nickel, 2.5-3.5% molybdenum and a small percentage of nitrogen. Providing corrosion resistance at the surface tensile strength (620-795 MPa) and yield strength (450 MPa a very low) with good stiffness and good elongation. Advantages include excellent resistance to pitting, cracking and stress corrosion cracking, superior strength and improved fatigue resistance. Compared to conventional stainless steel these properties make it suitable for areas a it is as complex as the marine and chemical industries the oil and gas industry.
