I overview of 2205(S3 1803, F5 1, 1.4462) duplex stainless steel:

2205(S3 1803, F5 1, 1.4462) dual-phase steel is a new product successfully developed in 2000. 2205 dual-phase steel is a kind of nitrogen-containing dual-phase stainless steel (2205 dual-phase steel for short), which is made of 2 1% chromium, 2. At present, domestic 2205 dual-phase steel products include welded pipe, seamless pipe, steel plate, bar, forged material, strip and so on. Early duplex stainless steel can resist uniform corrosion and chlorine stress corrosion cracking with moderate strength, but its performance will be greatly reduced when used in welding. In order to improve this situation, nitrogen is added to 2205 dual-phase steel, which not only improves the corrosion resistance, but also has good welding application. It has high strength, good impact toughness and good overall and local stress corrosion resistance.
