Exaton 31S

Exaton 31S is a neutral welding flux for submerged arc welding (SAW/ESW) that delivers good slag removal and a fine bead appearance. It is designed for surfacing with strip and wire electrodes, especially the 310LMo type, and can also be used for joining applications.

Key Features

• Neutral flux providing easy slag removal and smooth bead
• Suitable for strip and wire electrodes (e.g., 25.22.2.LMn) in urea applications
• High corrosion‑resistant chemistry with increased Cr and Mo content
• Packaged in moisture‑resistant steel drums (20‑25 kg)
• Improves productivity by allowing single‑layer cladding where multiple layers were previously required

Specifications

• Classifications: EN ISO 14174 : S A AB 2
• Welding Current: 1200 A
• Density: 0.9 kg/L (nominal)
• Basicity Index: 1.0 (nominal)

Applications

• Submerged Arc Welding (SAW) of stainless steel in heavy‑duty environments
• Strip cladding and wire cladding of stainless steel and nickel alloys
• Urea plant equipment welding
• General joining where high corrosion resistance is required
