Duplex 2205 stainless steel (both ferritic and austenitic) is used extensively in applications that require good corrosion resistance and strength. The S31803 grade stainless steel has undergone a number of modifications resulting in UNS S32205, and was endorsed in the year 1996. This grade offers higher resistance to corrosion.
At temperatures above 300°C, the brittle micro-constituents of this grade undergo precipitation, and at temperatures below -50°C the micro-constituents undergo ductile-to-brittle transition; hence this grade of stainless steel is not suitable for use at these temperatures.
Duplex 2205, also known as UNS S32205, is a nitrogen-enhanced stainless steel. Users choose Duplex 2205 for its excellent corrosion resistance along with its high strength. It is important to note that Duplex 2205, offers much higher levels of corrosion resistance than most other austenitic stainless steels. Other benefits include:
