Exaton 15W

Exaton 15W is a basic welding flux for submerged arc welding (SAW) that offers good slag removal and a fine bead appearance, suitable for stainless and duplex steels where high impact strength is required.

Key Features

• High basicity for austenitic and duplex stainless steel welding
• Low niobium burn‑off, compatible with stabilized wire electrodes
• Excellent bead appearance and self‑slag release
• Reduces moisture damage with steel drum packaging (20‑25 kg drums)
• Improves productivity and lowers operating costs

• Classifications: EN ISO 14174 : S A AF 2
• Approvals: CE EN 13479, UKCA EN 13479
• Welding Current: 1200 A (using 60×0.5 mm strip)
• Slag Type: Fluoride basic CaF₂‑Al₂O₃‑SiO₂
• Density: 1.0 kg/L (nominal)
• Basicity Index: 1.9 (nominal)
• Flux consumption (SAW): 26 V → 0.5 kg, 30 V → 0.6 kg, 34 V → 0.8 kg, 38 V → 1.0 kg

Applications

• Submerged arc welding of stainless and duplex stainless steels in chemical, petrochemical and oil & gas industries
