Exaton 22.12.HT (GTAW)

Exaton 22.12.HT is an austenitic stainless steel filler material for welding high‑temperature steel grades such as UNS 30815 and EN 1.4835. It offers high creep strength, good oxidation resistance and excellent weldability.

Key Features

• Designed for SAW stainless steel welding in heavy‑duty environments
• Consistent wire quality with tight chemistry and mechanical tolerances
• Innovative corrosion‑resistant chemistry with high Cr and Mo content
• Low‑moisture SAW flux packaging (20‑25 kg drums) for reduced damage
• Cost‑effective flux delivering higher speed and fewer cladding layers
