Duplex 2205 has excellent corrosion resistance, especially chloride-induced stress corrosion cracking. In addition to its resistance to pitting and crevice corrosion, it is suitable for use in various corrosive environments. The alloy's high chromium and molybdenum content provide excellent resistance to general corrosion, while the nickel content improves its resistance to stress corrosion cracking.
The corrosion resistance of Duplex 2205 is superior to that of standard austenitic stainless steel grades, such as 304 and 316, and is roughly comparable to the corrosion resistance of alloy 317L. Compared to other stainless steel alloys, the duplex microstructure of Duplex 2205 offers superior corrosion resistance.
Duplex 2205 has excellent corrosion resistance, but it may be susceptible to corrosion in specific environments, particularly in the presence of chlorides or other aggressive chemicals. To ensure the alloy's long-term performance in corrosive environments, its selection, fabrication, installation, and maintenance must be performed correctly.
Although Duplex 2205 has good heat resistance, it is not as resistant to heat as other stainless steel alloys. It can withstand temperatures up to approximately 260 degrees Celsius (500 degrees Fahrenheit), but its heat resistance decreases at higher temperatures. Duplex 2205 has a lower heat resistance than austenitic stainless steel grades such as 304 and 316 because of its duplex microstructure.
However, Duplex 2205 is suitable for many applications in high-temperature environments due to its excellent heat, high strength, and corrosion resistance. Heat exchangers, pressure vessels, and other equipment requiring high strength and corrosion resistance frequently employ this alloy.
Notably, the heat resistance of Duplex 2205 can be affected by other variables, such as the presence of contaminants, the rate of heating and cooling, and the type of thermal treatment applied. Its selection, fabrication, installation, and maintenance practices must be carefully considered to ensure the alloy's long-term performance in high-temperature environments.

Welding Duplex 2205 has excellent weldability and can be easily welded using common welding techniques, including Gas Tungsten Arc Welding (GTAW), Gas Metal Arc Welding (GMAW), and Shielded Metal Arc Welding (SMAW). To prevent cracking, it is essential to control the heat input during welding, particularly in thicker sections. To ensure maximum corrosion resistance, Duplex 2205 welds should also be subjected to a heat treatment after welding.
Duplex 2205 can be heat treated to improve its mechanical properties, but this is rarely required. If heat treatment is required, solution annealing should be followed by rapid cooling. The alloy may also be subjected to a stress relief treatment, but this must be carefully regulated to avoid cracking.
Duplex 2205 can be hot formed using standard hot forming techniques, including hot forging and rolling. To ensure maximum strength and corrosion resistance, hot forming should be conducted at temperatures between 1700°F (925°C) and 2250°F (1230°C), with the correct heating and cooling rates.
Duplex 2205 can be cold-formed using standard cold-forming techniques, including cold rolling and drawing. Cold forming must be performed at room temperature or below to prevent cracking and to ensure maximum strength and corrosion resistance.
Duplex 2205 can be machined less easily than other stainless steel alloys. Utilizing the correct cutting parameters and tool geometries can improve its machinability, but care must be taken to avoid cracking.
Duplex 2205 is highly fabricable and can easily work with standard fabrication techniques, such as bending, stamping, and forming. Essential for preventing cracking and ensuring maximum strength and corrosion resistance is proper fabrication process control. The alloy's high strength makes it suitable for high-stress applications, but it is more challenging to work with than other stainless steel alloys.

To specify the various physical and mechanical properties of the finished product, various tests, both destructive and nondestructive, are performed. Metallurgical, hardness, hardenability, tension, ductility, compression, fatigue, impact, wear, corrosion, creep, machinability, radiography, magnetic particle, ultrasonic, and eddy current are some of the major tests that are performed by quality control personnel. Metallurgical testing is used to determine the quality of steel by analyzing the microstructure of a sample under a microscope. A cross section of a sample is first highly polished and then examined at a magnification from 100-500 diameters. The microstructure of steel consists of grains of different compositions and sizes.
