OK Flux 10.99

OK Flux 10.99 is a neutral agglomerated basic flux designed for the submerged arc welding (SAW) of austenitic stainless steels and Ni‑based alloys, usable with both AC and DC+ currents. It delivers good mechanical and impact properties, excellent weldability in 1G/2G positions and self‑lifting slag.

Key Features

• Neutral basic flux with high basicity (index 2.1) for improved impact values
• Compatible with AC and DC+ current modes
• Self‑lifting slag for clean bead appearance
• Suitable for stainless steels and Ni‑based alloys
• Good weldability in 1G and 2G positions
