Duplex 2205 SS Stainless Steel Plate Coil - Astm / Asme : A240 Uns S31803 / S32205

# Duplex 2205 properties

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:

1. High resistance to pitting and crevice corrosion

2. Excellent in most caustic environments

3. Good weldability
