Exaton 24.13.LNb (SAW)

Exaton 24.13.LNb is a niobium‑stabilized, overalloyed filler metal designed for overlay welding of carbon and low‑alloy steels where a type 347 overlay is required. It is intended for Submerged Arc Welding (SAW) and is used with the recommended Exaton 15W flux.

Key Features

• Niobium‑stabilized chemistry for excellent corrosion resistance
• Consistent wire quality batch‑to‑batch
• High chromium and molybdenum content for improved durability
• Available in 20–25 kg drums with moisture‑resistant packaging
• Reduces the number of required cladding layers, lowering cost
