Chemical composition and duplex structure
2205 stainless steel contains 22% chromium, 3% molybdenum and 4.5%-6.5% nickel, and has both ferrite and austenite phases. The yield strength can reach 450-620 MPa, which is twice that of ordinary austenitic stainless steel. This duplex structure gives it both high strength and good toughness, and can maintain structural stability when under pressure.
Corrosion resistance
Its pitting resistance equivalent (PREN value 33-35) is better than 316L/317L austenitic stainless steel in most corrosive media, especially suitable for chloride environments, and can effectively prevent stress corrosion cracking. The addition of nitrogen further enhances the ability to resist crevice corrosion, and performs outstandingly in marine and chemical scenes.
Processing and welding characteristics
2205 stainless steel can be cold-formed or hot-formed (recommended temperature ≤600°F), and attention should be paid to springback control during processing. Welding does not require preheating or post-treatment, and the joint strength is equivalent to that of the parent material, which is suitable for complex structure manufacturing

Composition of Stainless Steel
Steel is an alloy of iron and carbon. Stainless steels are steels containing at least 10.5% chromium, less than 1.2% carbon and other alloying elements. Stainless steel’s corrosion resistance and
mechanical properties can be further enhanced by adding other elements, such as nickel, molybdenum, titanium, niobium, manganese, etc.
