ASTM A790 Duplex Steel Gr.2205 / UNS S32205 Pickled and Annealed Seamless Pipe
ASTM A790 Gr 2205 / UNS S32205 Seamless Pipe is a premium, high-performance material that offers an outstanding combination of very high strength and excellent corrosion resistance, particularly against pitting, crevice corrosion, and chloride stress corrosion cracking. Its "duplex" structure makes it a cost-effective solution for some of the most challenging environments in the oil & gas, chemical, and marine industries, often bridging the gap between standard austenitic steels and more expensive nickel alloys. Proper fabrication techniques are paramount to preserving its superior properties.
