2205 duplex stainless steel is a high-performance alloy that combines the advantages of austenitic and ferritic stainless steels, providing an ideal solution for harsh working conditions. This article will introduce its composition, characteristics, advantages and common applications.
Composition of 2205 duplex stainless steel
The numbers in 2205 stainless steel represent its chromium (22%) and nickel (5%) content, while elements such as molybdenum (about 3%) and nitrogen are added to enhance corrosion resistance, allowing it to be widely used in industries that require high strength, corrosion resistance and durability. . Its duplex structure (about 50% austenite and 50% ferrite) makes its mechanical properties better than ordinary austenitic or ferritic stainless steel.
Main characteristics of 2205 duplex stainless steel
1. High strength and high toughness: The yield strength of 2205 stainless steel is twice that of 316L stainless steel, suitable for high-pressure environments.
2. Excellent corrosion resistance: It has strong resistance to pitting, crevice corrosion and stress corrosion cracking, especially suitable for chloride-containing environments.
3. Good weldability and machinability: Although more difficult to machine than standard austenitic stainless steel, the correct process ensures strong welds and easy machinability.
4. Cost-effective: Its durability reduces long-term maintenance and replacement costs.
Advantages compared to other stainless steels
Compared with 304/316 stainless steel: Higher strength and corrosion resistance, especially suitable for harsh environments such as chemical or marine.
Compared with super duplex steel (such as 2507 stainless steel): More affordable, while meeting the high performance requirements of most applications.
Common applications of 2205 duplex stainless steel
Oil and gas industry: Pipes, valves and pressure vessels.
Chemical processing: Storage tanks and heat exchangers.
Marine and marine structures: Hulls, pumps and accessories.
Paper industry: Equipment exposed to corrosive chemicals.
