What are Duplex 2205 Pipes?

Duplex 2205 pipes are stainless steel pipes made from a duplex alloy (UNS S32205/S31803) that combines austenitic and ferritic microstructures. They offer high strength, excellent corrosion resistance (especially against chloride stress corrosion cracking), and superior durability, making them ideal for demanding industrial environments.

What is Duplex 2205 Stainless Steel?

Duplex 2205, also known as UNS S32205, is a nitrogen-enhanced duplex stainless steel designed to provide better resistance to corrosion than standard austenitic grades like 304 and 316.

It features:

• Dual-phase microstructure (austenite + ferrite)
• Higher yield strength (almost double compared to standard stainless steels)
• Exceptional resistance to pitting and crevice corrosion

Because of these properties, DSS 2205 seamless pipe is widely used in environments where both strength and corrosion resistance are critical.

Key Features of Duplex 2205 Pipes

• High strength (2x standard stainless steel)
• Excellent corrosion resistance
• Resistance to stress corrosion cracking
• Good weldability and fabrication properties
• Long service life in harsh environments

These properties make Duplex 2205 pipes a preferred choice for demanding industrial conditions.
