ASTM A790 Duplex Steel 2205 / UNS S32205 Seamless Duplex Stainless Steel Pipe

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.

Here are some key features:

• Strength: Duplex S32205 has higher strength than standard austenitic stainless steels.
• Corrosion Resistance: Excellent resistance to both pitting and crevice corrosion, particularly in chloride environments. 
• Weldability: Good weldability, though it requires proper techniques to avoid issues like hot cracking.
• Toughness: Retains good toughness even at low temperatures. 
• Sustainability: Often considered for applications due to its recyclability
