Properties of Super Duplex Steel:
Additional processing can be used to strengthen Super Duplex Steel Fasteners. For instance, Hardening Super Duplex stainless steel fasteners increase yield stress and ultimate tensile strength while decreasing flexibility. Cold forming can be used to strengthen the steel, which can increase its strength in some situations but is only suitable for smaller diameter bars. The steel demonstrates weak toughness under impact loads. This is an acceptable feature if the component will be functioning under tension with little impact loads.

Uses of Super Duplex Steel Fasteners:
Super Duplex stainless steel is a high-alloy duplex stainless steel that combines the strengths of ferritic and austenitic steel. It is stronger than ferritic steel grades and more corrosion resistant. Pipelines of Oil and gas, seawater heat exchangers, saltwater handling equipment, desalination equipment, scrubber systems in power plants, process vessels holding aggressive media, and liquefied natural gas tanks are all made of super duplex stainless steel.

What is a Super Duplex Steel?
Because of their unique mix of strength, corrosion resistance, and cost-effectiveness, super duplex stainless steels are particularly well suited to the manufacturing of fasteners for industrial applications. Duplex stainless steel joins the characteristics of both austenitic and ferritic stainless sheets of steel, such as high strength and toughness, ease of manufacture, and corrosion cracking resistance. Super duplex stainless steel, a sort of duplex stainless steel has greater than 40 PREN.
