What is the material of SS2205?
SS2205 belongs to duplex stainless steel.

China brand: 00Cr22Ni5Mo3N, F5 1/F60. American brand: UNS S3 1803/S32205. German brand: 1.4462.

2205(S3 1803, F5 1, 1.4462) duplex stainless steel is a kind of nitrogen-containing duplex stainless steel, which is composed of 2 1% chromium, 2.5% molybdenum and 4.5% molybdenum. 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.
