Super Duplex Germany
Super Duplex is a high-alloy of duplex. Most grades of Super Duplex contain 25% or more along with other elements like molybdenum, nickel and nitrogen but different grades can also have tungsten and copper in trace amounts. They have a PREn greater than or equal to 40 and have excellent mechanical properties, high strength but also highly corrosion resistant, weld-ability and work-ability. It offers low rate of thermal expansion and can be used in applications where the temperature is high.
World Leaders in Super Duplex steel
At Faco Fasteners, we offer several grades of Super Duplex materials. The different grades of fasteners contain different elements in trace or higher quality and this leads to several different properties. We offer Super Duplex grades that offer high resistance to inorganic acids and is highly resistant to carbide-related intergranular corrosion. We also offer grades of Super Duplex that offer high resistance to chloride stress corrosion cracking, excellent resistance to chloride pitting and crevice corrosion, this type of grade has a high level of molybdenum, chromium and nitrogen content. Super Duplex is known for its good strength, ductility and high corrosion resistance, ideal for a variety of fasteners, thus it is used in a wide range of industries like Oil & Gas, defence, pollution control, chemical/ petrochemical, nuclear and marine applications.
