OK Flux 10.78

OK Flux 10.78 is an agglomerated aluminate‑basic flux designed for Submerged Arc Welding (SAW). It provides a very good surface finish, excellent slag detachability and supports high welding speeds for plate thicknesses up to about 25 mm.

Key Features

• Aluminate‑basic slag for easy removal
• Moderately silicon alloying, low manganese content
• Suitable for both DC+ and AC processes, single and multi‑wire procedures
• High welding speeds; ideal for concave horizontal fillet and butt welds
