Product Description
ASTM A790 UNS S31803 SOUR 2205 Stainless Steel Pipe is a duplex stainless steel pipe specifically designed for sour service environments containing hydrogen sulfide (H₂S). It combines the advantages of both austenitic and ferritic stainless steels, offering excellent corrosion resistance, high strength, and outstanding resistance to chloride stress corrosion cracking.
The SOUR designation indicates that the material complies with sour service requirements commonly used in oil and gas production environments, typically meeting the requirements of standards such as NACE MR0175 / ISO 15156.
