Duplex 2205(UNS S31803/UNS S32205/1.4462) is a nitrogen enhanced duplex stainless steel that was developed to combat common corrosion problems encountered with the 300 series stainless steels. “Duplex” describes a family of stainless steels that are neither fully austenitic, like 304 stainless, nor purely ferritic, like 430 stainless. The structure of 2205 duplex stainless steel consists of austenite pools surrounded by a continuous ferrite phase. In the annealed condition, 2205 contains approximately 40-50% ferrite. Often referred to as the work horse grade, 2205 is the most widely used grade in the duplex family of stainless steels.

1.Corrosion Resistance: 2205 stainless stands-up excellently in a range of atmospheric environments even when exposed to corrosive elements, specifically to sea water.
2.Heat Resistance: Generally, 2205 is not suitable for use at temperatures above 300°C as it suffers from precipitation of brittle micro-constituents.
3.Avoid temperatures below -50°C because of its ductile-to-brittle-transition.
4.Easy to weld with excellent weldability.
5.The high strength of 2205 also makes bending and forming more difficult.
| Surface Finish | Definition | Application |
| 2B | Finished by heat treatment , picking or equipvalent cold rolling , followed by skin pass to obtain adequate luster surface. | With bright and smooth surface ,easy for further grinding to obtain brighter surface ,suitable for medical instruments ,milk containers ,tableware and so on. |
| BA | Bright heat treatment after cold rolling. | Structual members .etc.kitchen utensil ,cutlery ,eleltric applicances ,medical instruments ,building decorations ,etc. |
| NO.3/NO.4 | Polished with No.150-240 abrasives. | Milky food processing equipment , medicalinstruments ,building decorations. |
| HL | Finshed by polishing with abrasives of suitable grain size to obtain continuous streaks. | Building decorations ,such as elevators ,escalators ,door etc. |
| 6K/8K | A mirror-like reflective surface ,which is obtained by polishing with successively finer abrasives and buffing extensively with all gritlines are removed. | Buliding entrances,bulkding column casting ,elevator's wall doors, counters,sculptur |
