What is Duplex Steel UNS S32205?

Duplex Steel UNS S32205 is a nitrogen-enhanced duplex stainless steel with a mixed microstructure of austenite and ferrite. This composition provides higher strength and improved corrosion resistance compared to standard stainless steel grades like 304 and 316.

Chemical Composition of Duplex Steel UNS S32205

• Chromium (Cr): 22-23%
• Nickel (Ni): 4.5-6.5%
•  
• Manganese (Mn): ≤ 2%
• Nitrogen (N): 0.14-0.2%
• Iron (Fe): Balance

Due to this unique composition, Duplex Steel UNS S32205 offers superior mechanical strength and corrosion resistance, making it ideal for demanding applications.
