Shield-Bright 347

Shield-Bright 347 is a gas‑shielded flux‑cored wire (FCAW/MCAW) designed for welding 18%Cr‑8%Ni‑Nb stainless steels such as grades 347, 304, 304L and 321 in all positions.

Key Features

• Provides flat weld deposits in all welding positions thanks to fast‑freezing slag.
• Rutile‑based slag system enables spray transfer mode with high currents and high deposition rates.
• Low spatter and easy slag release, even in V‑butt joints.
• Niobium addition reduces chromium carbide precipitation for improved corrosion resistance.
