Product Description

Duplex Steel 2205 Seamless Tube

Duplex Steel 2205 Seamless Tube is a nitrogen-enhanced duplex stainless steel specifically engineered to address common corrosion challenges encountered with 300 series stainless steels. The "duplex" classification refers to stainless steels that combine both austenitic and ferritic microstructures. In the 2205 alloy, this results in austenite pools surrounded by a continuous ferrite phase, with approximately 40-50% ferrite in the annealed condition. As the most widely used grade in the duplex family, 2205 is often considered the workhorse alloy for demanding industrial applications.

The duplex structure provides significant advantages by combining the beneficial properties of ferritic alloys—such as stress corrosion cracking resistance and high strength—with those of austenitic alloys, including excellent fabrication characteristics and superior corrosion resistance.

Note: Application of 2205 Duplex stainless steel should be limited to temperatures below 600°F, as prolonged exposure to elevated temperatures can cause embrittlement.

Key Features
