Veer Flanges is a reputable manufacturer and supplier of Super Duplex Steel Flat Flanges based in Kolkata, India. They specialize in precision-engineered flange solutions that are built to last, offering exceptional strength, durability, and resistance to corrosion. These flat flanges feature a flat face and are typically used in low-pressure piping systems that need to be taken apart frequently. Crafted from high-quality Super Duplex Steel, these flanges are highly regarded for their ability to withstand chloride stress corrosion cracking, pitting, and general corrosion. Veer Flanges adheres to international standards like ASTM, ASME, and ANSI, serving a variety of industries such as chemical processing, desalination, marine, and oil & gas.
Super Duplex Steel Flat Flanges are crafted from an alloy that includes 24–26% chromium, 6–8% nickel, 3–5% molybdenum, and 0.2–0.3% nitrogen, with the remainder being iron and trace elements. Their unique austenitic-ferritic structure provides impressive strength and outstanding corrosion resistance. These flanges boast a tensile strength of at least 800 MPa, a yield strength of at least 550 MPa, and an elongation of about 25%. They are known for their excellent resistance to pitting, crevice corrosion, and chloride-induced stress corrosion cracking, making them a reliable choice for tough applications in harsh, corrosive settings.
