2205 Duplex Stainless
2205 duplex stainless combines the strength benefits of ferritic-austenitic structure with strong resistance to chloride-related corrosion. It is widely used for pressure, process, and marine systems where 316L no longer provides enough pitting or SCC resistance. EQI supplies 2205 for plate, bar, and fabricated corrosion service.
- UNS S31803 / S32205
