About Duplex 2205

Duplex 2205 is prima donna of duplex stainless steel alloys. Often referred as Alloy 2205 or by UNS equivalent S31803 & S32205, this duplex alloy is a major choice for fastener manufacturing. Duplex 2205 is superior to 300 series stainless steel in terms of strength and general corrosion resistance. Duplex 2205 has improved resistance to pitting and crevice. Duplex 2205 is ideally suited for high pressure, high corrosive environment.
