Exaton 22.8.3.L (SAW)

Exaton 22.8.3.L is a duplex stainless steel filler metal designed for Submerged Arc Welding (SAW) of duplex stainless steels such as SAF 2205 and SAF 2304, as well as for cladding and joining to carbon steel. It offers excellent weldability, corrosion resistance comparable to 904L, and consistent wire quality.

Key Features

• Duplex stainless filler metal with high Cr and Mo content for superior corrosion resistance
• Consistent chemistry and mechanical properties batch‑to‑batch
• Low‑moisture SAW flux packaging in 20‑25 kg drums
• Enables single‑layer weld overlays in applications that previously required multiple layers
• Compatible with Exaton 15W flux
