Duplex Steel Flanges typically consist of about 22% chromium, 5–6% nickel, 3% molybdenum, and nitrogen, which together provide exceptional strength and corrosion resistance. This alloy boasts nearly double the yield strength of standard austenitic stainless steels while still maintaining good ductility and impact toughness. Duplex flanges are known for their excellent resistance to pitting, crevice corrosion, and chloride stress corrosion cracking, making them a reliable choice for harsh conditions. With great weldability, machinability, and precise dimensions, Duplex Steel Flanges guarantee secure connections and leak-proof performance in demanding piping systems.
