Audited Supplier Duplex Steel of material includes grades 2205, F51, F53, and F60. Duplex stainless has increased in popularity over the years due to its excellent chemical and mechanical properties versus their basic stainless counterparts, given especially that the cost differences are minimal now as the availability has increased.
The granular structure of duplex is a ferrite-austenite hybrid with a superior strength to weight ratio in comparison to 304 or 316. It balances the weldability of an austenitic with a pure ferritic and retains decent mechanical toughness in applications with exposure to colder ambient temperatures. Offshore/seawater applications are a common use for this type of steel due to its excellent stress corrosion cracking properties. Therefore, duplex is often found in desalination and pressure vessel equipment located in port cities.
Duplex's premium mechanical and chemical properties are slightly offset by its difficulty in formability. These grades are excellent for fixed service simple flange connections, but slightly less so when forming a complex metallic shape. Fortunately, the workability of duplex into complex and rounded structures is less of an issue in structural steel given the wide preference for simple mild steel in non corrosive applications.
