High Strength UNS S32205 2205 Duplex Stainless Steel Rod Full Diameter 10 - 300mm
Product Description
2205 stainless steel (also known as duplex stainless steel) is a high-performance stainless steel material with excellent corrosion resistance, high strength and good toughness.
Chemical Composition and Physical Properties
The main chemical components of 2205 stainless steel include chromium (Cr), nickel (Ni), molybdenum (Mo) and nitrogen (N). Its chromium content is about 22%, nickel content is about 4.5% to 6.5%, molybdenum content is about 2.5%, and nitrogen content is about 0.14% to 0.20%. The reasonable ratio of these elements makes 2205 stainless steel have excellent corrosion resistance and high strength.

Performance Characteristics
- Corrosion resistance: 2205 stainless steel has excellent resistance to pitting corrosion, crevice corrosion and stress corrosion cracking, and is suitable for a variety of harsh environments, especially in environments containing chloride ions.
- High strength: Its yield strength and tensile strength are higher than those of ordinary austenitic stainless steel, and it can withstand greater external forces and pressures.
- Good toughness: Even in low temperature environments, 2205 stainless steel can maintain good toughness and impact toughness, and is not prone to brittle fracture.
- Weldability: It has good welding performance. Common welding methods include TIG welding, MIG welding and manual arc welding.
Application Fields
Due to the excellent performance of 2205 stainless steel, it is widely used in many fields:
- Petroleum, chemical and marine engineering: It is used to manufacture key equipment such as pipelines, storage tanks, valves and reactors.
- Food processing and medical equipment: It is often used in food processing equipment and medical equipment due to its corrosion resistance and easy cleaning.
High Temperature Mechanical Properties
Maintenance and Care
During use, the following points should be noted:
- Avoid high temperature environment: Although 2205 stainless steel has high heat resistance, its performance may be affected in high temperature environment for a long time.
- Correctly select welding method: Ensure the performance and reliability of the welding joint and select suitable welding method and parameters.
- Regular maintenance: Regularly inspect and maintain equipment to detect and deal with potential problems in time.
