Duplex 2205 sheet (UNS S32205 / S31803) is ideal for high pressure and highly corrosive environments. Stress corrosion cracking is often a barrier to using 304L, 316L, or 317L when necessary conditions such as temperature, tensile stress, oxygen, and chlorides are present. Compared to other stainless steels, SS 2205 has high strength, low thermal expansion, and is easily welded.
