Technically, the microstructure of a duplex 2205 tube is approximately 50% ferrite and 50% austenite. As a result, the properties inherited from both categories make this nitrogen-enhanced duplex 2205 seamless pipe ideal for use in industries such as food processing, oilfield piping and heat exchangers, and flue gas desulfurization.
The temperature in heat exchange is usually increased because they work according to the principle of heat transfer. While A789 tubing can hold its own at high temperatures, it is not recommended for use in temperatures above 600F. Duplex 2205 Tube may become brittle and rot at temperatures above 600F.
Duplex 2205 pipe is stainless steel. It belongs to a family of stainless steels called duplex steels. There are different groups of this material.

The service temperature of 2205 duplex stainless steel should be limited to below 600¡ãF. Prolonged exposure to high temperatures can make 2205 stainless steel brittle.
For many applications where 300 series stainless steel is susceptible to chloride stress corrosion cracking, 2205 duplex stainless steel is a cost-effective solution. Stress corrosion cracking occurs when stainless steel is subjected to tensile stress while in contact with solutions containing chlorides. Elevated temperatures also increase the susceptibility of stainless steel to stress corrosion cracking.
