Super/Duplex Stainless Steel Wire, Duplex 2205, 2507

 

Duplex Stainless Steel Wire

Duplex stainless steel wire, also known as austenitic-ferritic stainless steel wire, is a series of grades with approximately equal proportions of ferrite and austenite, containing a mixture of austenite and ferrite in its structure. It has two-phase properties, excellent corrosion resistance and high mechanical strength. Duplex stainless steel wire contains high content of chromium (19%-28%) and low to medium amount of nickel (0.5%-8%). Duplex 2205 (UNS S32205) is one of the most widely used duplex stainless steels, Hightop also offers UNS S31803, and super duplex such as Zeron 100 (UNS S32760) and 2507 (UNS S32750) which is suitable for harsh corrosive environments.
