2205 Duplex Stainless Steel Sheet & Plates ASTM A240 for Pressure Vessel EN 1.4462

Products Specification

2205 duplex stainless steel sheet is a type of stainless steel that contains both austenitic and ferritic phases. It is a popular choice for applications that require high strength and resistance to corrosion, such as in the chemical, petrochemical, and oil industries. This material can also be used in the marine and offshore industries, as well as in the manufacturing of heat exchangers and pressure vessels. 2205 duplex stainless steel sheet has excellent mechanical properties, including high toughness, fatigue resistance, and good weldability. It also offers good resistance to chloride stress corrosion cracking, making it a reliable choice for harsh environments.

1. Superior corrosion resistance: Duplex Stainless Plate has excellent resistivity to corrosion caused by various substances such as acids, salts, and alkalis.

2. High strength: Compared to other types of stainless steel, Alloy 2205 duplex stainless steel plate has a higher yield and tensile strength, making it suitable for heavy-duty applications.

3. Improved durability: The addition of chromium, molybdenum, and nitrogen in the composition of 2205 Stainless Steel Sheet enhances its durability and makes it resistant to wear and tear.

4. Cost-effective: 2205 duplex stainless steel is cost-effective compared to other types of stainless steel as it reduces the need for protective coatings and maintenance.

5. Versatile: This stainless steel is versatile and used in a wide range of applications such as chemical processing equipment, heat exchangers, oil and gas pipelines, and pulp and paper industry.

6. Better weldability: The low thermal expansion and high conductivity of Duplex 2205 make it easier to weld than other types of stainless steel.

7. Excellent ductility: The high strength and excellent ductility of this stainless steel sheet make it suitable for complex shapes and designs.

Surface of 2205 Duplex Stainless Steel Plate

2205 duplex stainless steel sheets can be finished in various ways to achieve different surface finishes such as:

1. No.1 (Hot Rolled Annealed and Pickled) – This is a rough surface finish achieved by hot rolling the sheet and then pickling it to remove any surface scale. This finish is suitable for applications where the appearance is not critical.

2. No.2B (Cold Rolled Annealed and Pickled) – This is a smooth surface finish achieved by cold rolling the sheet after annealing and then pickling it to remove any surface scale. This finish is commonly used in industrial applications.

3. BA (Bright Annealed) – This is a highly reflective surface finish achieved by annealing the sheet in a controlled atmosphere furnace and then pickling it to remove any surface oxide. This finish is popular for decorative applications such as trim and exhaust systems.

4. Brushed Finish – This is a surface finish achieved by brushing the sheet with an abrasive material to give a directional grain. This finish is used in architectural and decorative applications.

5. Satin Finish – This is a surface finish achieved by sandblasting or chemical etching the sheet to create a pattern on the surface. This finish is popular in the elevator and interior design industries.

6. Matte Finish – This is a surface finish achieved by electrochemical polishing the sheet to give a matte appearance. This finish is used in medical and pharmaceutical applications.
