Description
ER 309 is a solid wire for TIG welding, available in a bright finish, that gives smooth flow, a stable arc, and is spatter-free under optimum welding conditions. It gives a radiographic-quality weld deposit. The weld metal has excellent mechanical properties and possesses good oxidation and scaling resistance at elevated temperatures. It is ideally suited for welding stainless steels, wrought and cast materials of similar composition, welding of 18/8-type stainless steels to carbon steels for buffer layers, welding the clad side of 18/8-clad stainless steels, etc. COMPOSITION OF ALL WELD METAL (%)
