King of Corrosion Resistance - 2205 Stainless Steel Plate - Sushang Steel

2205 Stainless Steel Plate

2205 stainless steel plate, also known as duplex stainless steel plate, is a stainless steel material with coexistence of ferrite and austenite. This steel plate combines the advantages of ferritic stainless steel and austenitic stainless steel, with high strength, excellent corrosion resistance and good welding performance. The 22 in 2205 stainless steel plate represents its alloy content, and 05 represents its unique duplex structure. In a variety of corrosive media, 2205 stainless steel plate shows excellent corrosion resistance, especially in environments containing chloride ions, its resistance to stress corrosion cracking is particularly outstanding.

Corrosion resistance of 2205 stainless steel plate

1. Uniform corrosion: Thanks to the content of chromium (22%), molybdenum (3%) and nitrogen (0.18%) in 2205 duplex steel, 2205 shows better corrosion resistance than 316L and 317L in most environments.

2. Local corrosion resistance: The high content of chromium, molybdenum and nitrogen in 2205 duplex steel makes it significantly resistant to pitting and crevice corrosion in oxidizing and acidic solutions.

3. Stress corrosion resistance: The duplex microstructure of 2205 duplex steel enhances the stainless steel's resistance to stress corrosion cracking. Under specific conditions of temperature, stress, oxygen and chloride, austenitic stainless steel is prone to chloride stress corrosion. Because these conditions are difficult to control, the use of 304L, 316L and 317L is limited in this regard.

4. Corrosion fatigue resistance: The high strength and corrosion resistance of 2205 duplex steel give it extremely high corrosion fatigue strength. Processing equipment is often affected by corrosive environments and cyclic loads, and these characteristics of 2205 make it very suitable for such applications.

2205 duplex stainless steel application areas

2205 duplex stainless steel has been widely used in many fields due to its unique alloy composition and excellent corrosion resistance. 1. In the oil and gas industry, 2205 duplex stainless steel is often used in pipelines, oil well equipment and chemical containers. Its excellent resistance to chloride stress corrosion ensures the long-term stable operation of the equipment in harsh environments.

2. In the chemical and petrochemical industries, 2205 duplex stainless steel is widely used in equipment such as reactors, heat exchangers and storage tanks due to its good tolerance to a variety of corrosive media.

3. In industries such as papermaking, food and beverage processing, 2205 duplex stainless steel is also favored for its corrosion resistance, high strength and good processing performance.

4. In agriculture, 2205 Stainless Steel Plate is also used in fertilizer industry, urea industry and phosphate fertilizer industry.

In short, 2205 duplex stainless steel plays an irreplaceable role in many key areas with its unique performance advantages.
