Exaton 34S

Exaton 34S is a neutral, slightly chromium‑compensating 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 and can also be used for joining applications, especially for austenitic stainless steel grades such as 19.9.LQ and 24.13.LQ in nuclear and chemical environments.

Key Features

• Neutral flux with slight chromium compensation for improved corrosion resistance
• Excellent slag removal and fine bead appearance
• Suitable for strip and wire electrodes in SAW/ESW processes
• Available in moisture‑resistant 20‑25 kg steel drums
• Consistent wire quality batch‑to‑batch for reliable welds
