What Is 2205 Grade Stainless Steel Coil?
Grade 2205 stainless steel is duplex stainless steel with roughly equal proportions of ferrite and austenite in the microstructure, offering high corrosion resistance, excellent strength and toughness, good weldability, and machinability. Commonly used in a variety of industries including chemical processing, oil and gas, pulp and paper, marine engineering, and more.
2205 stainless steel coil is a popular product among duplex stainless steel coils. Coils made of 2205-grade stainless steel are processed and shaped through different processes such as hot rolling, cold rolling, drawing, and forging. After processing, surface treatments such as cutting, polishing, and passivation are performed to improve its mechanical properties and corrosion resistance. It is suitable for environments with high corrosion resistance requirements. Such as chemical industry, marine engineering, offshore oil and gas extraction, etc.

2205 Stainless Steel Coil
Duplex Properties of 2205 Stainless Steel Coil
The structure of the 2205 stainless steel coil is a duplex structure consisting of a continuous ferrite phase and austenite phase.
Austenite: Austenite is a face-centered cubic crystal structure with good corrosion resistance and welding performance. It exists in the form of tissue in 2205 stainless steel coils, forming an austenite pool.
Ferrite: Ferrite is a body-centered cubic crystal structure with good plasticity and toughness. The austenitic pool is continuously surrounded by coils of 2205 stainless steel.
This duplex structure makes 2205 stainless steel have both the advantages of austenitic stainless steel and ferritic stainless steel. Combining high strength, corrosion resistance, and good plasticity, it has become an important material widely used in many fields. Whether it is in the highly corrosive environment of the chemical industry, petroleum, marine engineering, and other fields, or the requirements of high strength and durability in pressure vessels, pipelines, heat exchangers, and other equipment, duplex stainless steel coils perform well.
2205 Stainless Steel Coil Properties
- Strong Corrosion Resistance: 2205 stainless steel coil has excellent corrosion resistance, especially stress corrosion resistance and chloride ion erosion resistance.
- Good Mechanical Properties: 2205 stainless steel coils have high strength and toughness, and can still maintain good performance in low-temperature environments.
- Good Welding Performance: 2205 stainless steel coils can be processed by conventional welding methods and have good weld performance.
- Good Processability: 2205 stainless steel coil has good plasticity and can be processed and formed in various ways.
- Moderate Price: Compared with other high-end stainless steel materials, the price of 2205 stainless steel coil is relatively moderate, and it is stainless steel material with high-cost performance.
Which Is Better 2205 or 316 Stainless Steel Coil?
Both 2205 stainless steel coils and 316 stainless steel coils are common stainless steel materials, which have certain advantages and scope of application, but the specific advantages and disadvantages depend on specific applications and needs, let’s find out next.
2205 stainless steel coil is a duplex stainless steel coil consisting of a ferrite phase and austenite phase. Its corrosion resistance is much higher than that of 316 stainless steel coils, and it also has good stress corrosion cracking resistance, good weldability, and wear resistance, especially suitable for marine environments and chemical fields.
But in terms of price, due to the duplex structure and higher alloy content of 2205 stainless steel coils, the price of 2205 stainless steel coils is also higher than that of 316 stainless steel coils.
If you need excellent corrosion resistance and strength, especially in chloride-rich environments, 2205 stainless steel coil will be your best choice; if cost-effectiveness is the main factor, and corrosion resistance is not required, 316 stainless steel A roll would be a little more appropriate.
In addition, factors such as processing performance, design requirements, and specific requirements of the environment need to be considered to make the best choice. If you have any questions or needs in this regard, please contact us! Gnee is always at your service.
