Super Duplex Italy
High-alloy of duplex stainless steel is commonly referred to as Super Duplex. They have a PREn greater than or equal to 40 and most grades contain 25% or more of chromium. It is made up of mostly chromium, molybdenum, nickel and nitrogen but different grades can also have tungsten and copper in trace amounts.
This material not only offers excellent mechanical properties, high strength but also highly corrosion resistant, weldability and workability. It offers low rate of thermal expansion and can be used in applications where the temperature is high. In addition, it offers a combination of properties of both austenitic and ferritic stainless steel and higher strength than both the materials.
Why buy Super Duplex from Faco Fasteners?
At Faco Fasteners, we offer grades of Super Duplex with high level of molybdenum, chromium and nitrogen content that offers high resistance to chloride stress corrosion cracking, excellent resistance to chloride pitting and crevice corrosion along with superior corrosion resistance in general. While other grades that contains chlorine offer high resistance to inorganic acids and is highly resistant to carbide-related intergranular corrosion. Since these materials offers good strength, ductility and high corrosion resistance, it is ideal for use in oil and gas, defence, pollution control, chemical/ petrochemical and marine applications.
