Exaton 49S

Exaton 49S is a basic, agglomerated flux for electroslag strip surfacing, designed for high‑speed welding of stainless‑steel and nickel alloys. It provides excellent slag removal and bead appearance, even with niobium‑alloyed strip electrodes.

Key Features

• Optimized for high welding speeds with consistent slag removal
• Suitable for chromium, chromium‑nickel, and chromium‑nickel‑molybdenum steel strips, with or without niobium
• High corrosion‑resistant chemistry (increased Cr and Mo content)
• Moisture‑resistant steel drum packaging (20‑25 kg drums)
• Improves productivity by reducing required cladding layers

Specifications

• Classification: EN ISO 14174 : ES A FB 2B
• Welding Current: 2200 A (using 60 × 0.5 mm strip)
• Slag Type: Fluoride basic CaF₂‑Al₂O₃
• Density: nominal 1.0 kg/L
• Basicity Index: nominal 4.4
• Operating Voltage: 25 V

Applications

• Electroslag welding (ESW) and strip surfacing of stainless steel
• Heavy‑duty environments requiring high corrosion resistance
• Projects where reduced number of cladding layers lowers cost
