StarBlaze MIG Wire ER347

StarBlaze MIG 347 (also commonly supplied as MIG 347/347H) is a high-performance, precision layer-wound solid austenitic stainless steel MIG welding wire. Classified under AWS A5.9 as ER347, this wire is niobium-stabilized (columbium-stabilized) to protect structural components from intergranular corrosion under high-temperature operating conditions.

Core Product Features
“StarBlaze MIG 347/347H is a G 19 9 Nb / ER 347H type solid MIG welding wire, supplied precision layer wound, depositing a Niobium stabilized 19Cr 9Ni weld metal...”
Anti-Precipitation Stabilization: The addition of niobium prevents chromium carbide precipitation at the grain boundaries, which virtually eliminates the risk of intergranular corrosion.
High-Temperature Integrity: Formulated for extreme service environments, providing excellent scaling resistance and mechanical stability at temperatures exceeding 400°C.
Exceptional Arc Control: Delivers a stable, low-spatter arc on direct current (DC+) with a brilliant, oxide-free wire surface that feeds smoothly through the torch liner.
Crack-Resistant Toughness: Possesses excellent structural ductility and crack resistance under hot cooling rates or continuous thermal fatigue.
