Washington Alloy, TT 2209 03, Welding Wire, 0.045 in, 36 in, Duplex Stainless Steel, ER2209, 100,000 psi min

ER2209 is a stainless steel alloy wire designed for welding AISI316 stabilized and 316Ti or 318 austenitic stainless steels. ER2209 produces duplex stainless steel weld deposits with a nearly balanced austenite-ferrite microstructure. ER2209 weld deposits exhibit high tensile strength, improved resistance to stress corrosion cracking and greater resistance to pitting than conventional austenitic grades of stainless steel. ER2209 is designed for welding 22% chromium duplex stainless steels such as ASMEASTM A-182, A-276, A-479, A-789, A- 790, and A-890. 3RE60®, 44LN® and Ferralium 255® are proprietary duplex stainless steel base metals in the 22% Cr category available commercially that can be joined successfully with ER2209. Non-proprietary grades 2205 and 2304 duplex stainless steels are also readily available, and can be joined successfully with ER2209.
