AWS A5.22 E2209T1-1/4
Premium 2209T1-1/4 duplex stainless-steel flux cored are used to weld 22% chromium duplex stainless steel such as 2205, 2209, 2304 and other proprietary duplex stainless steels. It has a smooth-running arc that deposits very high tensile strength, with resistance to stress, corrosion, cracking and pitting.
Premium 2209T1-1/4 may also be a good choice when welding Duplex stainless such as 2553 to carbon steels or other grades of stainless. Duplex has a two-phase micro structure of austenite and ferrite giving it great pitting or stress corrosion cracking and attack.
