Exaton 19.12.3.LR

Exaton 19.12.3.LR is a chromium‑nickel‑molybdenum covered electrode with a rutile coating designed for welding low‑carbon, molybdenum‑alloyed austenitic stainless steels (316L and equivalents). It provides high corrosion resistance and consistent weld quality for a wide range of stainless, ferritic and martensitic steels.

Key Features

• Rutile‑type coating for stable arc and easy slag removal
• High Cr and Mo content for excellent corrosion resistance
• Consistent chemistry and mechanical properties batch‑to‑batch
• Available in 20–25 kg drums with moisture‑resistant packaging
• Suitable for SAW (Submerged Arc Welding) in heavy‑duty environments
