Duplex Steel Forged fittings | UNS S31803, S32205

Nine Piping Solutions are seller and trader of Duplex S31803 / S32205 Forged Socket Weld Fittings, which is available at reasonable price for our esteemed clients. Chloride stress corrosion cracking of Duplex S31803 Forged Socket Weld Elbow Fittings can occur when the necessary conditions of temperature, tensile stress, oxygen, and chlorides are present. Because these conditions in Duplex S32205 Forged Socket Weld Tee Fittings are not easily controlled and are often characteristic of the operating environment, SCC has sometimes been a barrier to the use of stainless steels. Duplex S31803 Forged Socket Weld Cap Fittings are especially susceptible to SCC, and even Type 317L is not resistant.

Duplex S31803 Forged Socket Weld Cross Fittings resists SCC in two sodium chloride-containing environments that provide meaningful results relating to many practical service applications. As with most austenitic stainless steels, these Duplex S32205 Forged Socket Weld Union Fittings will not resist boiling 42 % magnesium chloride, but this environment is rarely encountered in service.
