Exaton 19.12.3.LSiMo (GMAW)

Exaton 19.12.3.LSiMo is a high‑performance MIG wire designed for welding austenitic stainless steel alloys (e.g., 316, 304, 321, 347) up to 400 °C. Its chemistry provides superior corrosion resistance thanks to increased Mo content.

Key Features

• Developed for heavy‑duty stainless steel welding (SAW, MIG/MAG, TIG, plasma)
• Consistent chemistry and mechanical properties batch‑to‑batch
• High corrosion resistance with ~2.9 % Mo
• Low‑moisture SAW flux packaging (20‑25 kg drums)
• Enables single‑layer overlay deposits, reducing labor and cost
